Why Custody Insurance Matters in September 2025

Institutions now hold billions in digital assets, and regulators expect professional risk transfer—not promises. Custody insurance providers bridge the gap by transferring losses from theft, key compromise, insider fraud, and other operational failures to regulated carriers and markets. In one line: custody insurance is a specialized policy that helps institutions recover financial losses tied to digital assets held in custody (cold, warm, or hot) when defined events occur. As spot ETF flows and bank re-entries accelerate, boards want auditable coverage, clear exclusions, and credible capacity. This guide highlights who actually writes, brokers, and structures meaningful digital-asset custody insurance in 2025, and how to pick among them. Secondary considerations include capacity, claims handling, supported custody models, and regional eligibility across Global, US, EU, and APAC.

How We Picked (Methodology & Scoring)

  • Scale/Liquidity (30%) — demonstrated capacity, panel depth (carriers/reinsurers/markets), and limits available for custody crime/specie.

  • Security & Underwriting Rigor (25%) — due diligence on key management, operational controls, audits, and loss prevention expectations.

  • Coverage Breadth (15%) — hot/warm/cold support, staking/slashing riders, social-engineering, wallet recovery, smart-contract add-ons.

  • Costs (15%) — indicative premiums/deductibles vs. limits; structure efficiency (excess, towers, programs).

  • UX (10%) — clarity of wordings, onboarding guidance, claims transparency.

  • Support (5%) — global service footprint, specialist teams (DART/crypto units), and education resources.

We prioritized official product/security pages, disclosures, and market directories; third-party datasets were used only for cross-checks. Last updated September 2025.

Integrating Crypto APIs with Google Sheets and Excel: A Complete Guide

Token Metrics Team
7
MIN

Staying on top of cryptocurrency markets often means harnessing real-time data and powerful analytics. For anyone seeking transparency and automation in tracking digital assets, connecting a crypto API directly to Google Sheets or Excel can transform your workflow. But how does the process actually work, and what are the best practices? Let’s break down the essential steps and considerations for integrating crypto APIs with your favorite spreadsheets, optimizing your data analysis, and ensuring reliability and security.

Choosing the Right Crypto API

The first step is selecting a crypto API suited to your needs. APIs are digital interfaces that let apps and platforms request data from cryptocurrency exchanges or analytics providers. Popular APIs deliver live prices, on-chain data, market caps, historical charts, and blockchain analytics.

  • Open vs. Restricted APIs: Some APIs are public and free; others require API keys and may have rate or usage limits.
  • Data Types: Consider if you need real-time price feeds, historical OHLCV data, on-chain analytics, or sentiment analysis.
  • Reliability & Security: Well-established APIs should offer robust documentation, strong uptime records, and clear usage policies.
  • Compliance: Ensure you use APIs that are legally authorized to distribute the type of crypto data you seek.

Examples of reputable APIs include Token Metrics, CoinGecko, CoinMarketCap, Binance, and CryptoCompare. Some, like Token Metrics, also offer AI-driven insights and advanced analytics for deeper research.

How to Connect a Crypto API to Google Sheets

Google Sheets offers flexibility for live crypto data tracking, especially with tools like Apps Script and the IMPORTDATA or IMPORTJSON custom functions. Here’s a general approach:

  1. Obtain Your API Endpoint and Key: Sign up for your preferred API (such as Token Metrics) and copy your endpoint URL and API key credentials.
  2. Install or Set Up Importer: For public APIs returning CSV data, use =IMPORTDATA(“URL”) directly in a cell. For JSON APIs (the vast majority), you’ll likely need to add a custom Apps Script function like IMPORTJSON or use third-party add-ons such as API Connector.
  3. Write the Script or Formula: In Apps Script, create a function that fetches and parses the JSON data, handling your API key in the request headers if needed.
  4. Display and Format: Run your script or enter your formula (e.g., =IMPORTJSON("https://api.tokenmetrics.com/v1/prices?symbol=BTC", "/price", "noHeaders")). Crypto data will update automatically based on your refresh schedule or script triggers.
  5. Automation & Limits: Be aware of Google’s rate limits and your API plan’s quota; set triggers thoughtfully to avoid errors or blocking.

Sample Apps Script for a GET request might look like:

function GETCRYPTO(url) {
  var response = UrlFetchApp.fetch(url);
  var json = response.getContentText();
  var data = JSON.parse(json);
  return data.price;
}

Change the URL as needed for your API endpoint and required parameters.

How to Connect a Crypto API to Excel

Microsoft Excel supports API integrations using built-in tools like Power Query (Get & Transform) and VBA scripting. Here is how you can set up a connection:

  1. Fetch the API Endpoint and Key: Obtain the endpoint and authorize via headers or parameters as your API documentation describes.
  2. Use Power Query: In Excel, go to Data > Get Data > From Other Sources > From Web. Enter the API URL, set HTTP method (typically GET), and configure authentication, if needed.
  3. Parse JSON/CSV: Power Query will ingest the JSON or CSV. Use its UI to navigate, transform, and load only the fields or tables you need (like price, symbol, or market cap).
  4. Refresh Data: When finished, click Load to bring dynamic crypto data into your spreadsheet. Setup refresh schedules as needed for real-time or periodic updates.
  5. Advanced Automation: For customized workflows (like triggered refreshes or response handling), leverage Excel’s scripting tools or Office Scripts in cloud-based Excel.

Note that Excel’s query limits and performance may vary depending on frequency, the amount of retrieved data, and your version (cloud vs desktop).

Best Practices and Use Cases for Crypto API Data in Spreadsheets

Why use a crypto API in your spreadsheet at all? Here are common scenarios and tips you should consider:

  • Portfolio Tracking: Dynamically update positions, track P/L, and rebalance based on real-time prices.
  • Market & Sentiment Analysis: Import on-chain or social sentiment metrics for enhanced research (available from providers like Token Metrics).
  • Historical Analysis: Pull historical OHLCV for custom charting and volatility tracking.
  • Custom Alerts or Dashboarding: Build automated alerts using conditional formatting or macros if price triggers or portfolio thresholds are breached.
  • Audit and Compliance: Keep timestamped logs or export data snapshots for reporting/transparency needs.

Security Tip: Always keep API keys secure and avoid sharing spreadsheet templates publicly if they contain credentials. Use environment variables or Google Apps Script’s Properties Service for added safety.

Troubleshooting, Rate Limits, and Common Pitfalls

Although spreadsheet integration is powerful, some challenges are common:

  • Rate Limits: Both Google Sheets/Excel and your crypto API will have tiered usage limits—avoid setting updates more frequently than permitted to prevent service interruptions.
  • Parsing Errors: Double-check API documentation for exact JSON/CSV field names required by your formulas or scripts.
  • Data Freshness: Sheet refreshes may lag a few minutes, so always verify the update interval matches your analysis needs.
  • Authentication Issues: If data fails to load, ensure API keys and headers are handled correctly and privileges have not recently changed.
  • Spreadsheet Bloat: Very large data pulls can slow down your spreadsheet—filter or limit queries to only what you truly need.

When in doubt, consult your API provider’s resource or developer documentation for troubleshooting tips and best practices.

FAQ: Connecting Crypto APIs to Google Sheets or Excel

Do I need programming knowledge to connect a crypto API?

Basic integrations, like using APIs that return CSV files, can often work without code via built-in data import features. For JSON APIs or custom data endpoints, familiarity with Apps Script (Google Sheets) or Power Query (Excel) is helpful but not strictly required, especially if you use add-ons like API Connector or plug-and-play solutions.

What types of crypto data can I import into spreadsheets?

Supported APIs offer a variety of data: live spot prices, historical price series, market capitalization, volume, on-chain metrics, sentiment scores, and more. The exact data fields depend on each API’s offering and the available endpoints.

How should I keep my API key secure in a spreadsheet?

Never embed plain text API keys in shared or public spreadsheets. In Google Sheets, use script properties or protected ranges; in Excel, store keys locally or use encrypted variables if automating. Always follow your provider’s credential management guidelines.

How frequently does spreadsheet crypto data refresh with APIs?

Refresh frequency depends on your integration setup. Google Sheets custom scripts or add-ons can update as often as every few minutes, subject to service and API rate limits. Excel’s Power Query typically updates manually or based on scheduled refresh intervals you define.

What’s the best crypto API for Google Sheets or Excel?

Choice depends on use case and data depth. Token Metrics is notable for real-time prices, AI-powered analytics, and robust developer support. Other popular choices are CoinGecko, CoinMarketCap, and exchange-specific APIs. Always compare data coverage, reliability, security, and documentation.

How Crypto APIs Power NFT and DeFi Data for Developers

Token Metrics Team
6
MIN

The explosion of NFT and DeFi applications has dramatically increased demand for reliable blockchain data. Developers and analysts seeking to build innovative crypto projects often ask: do crypto APIs provide data for NFTs and DeFi protocols—and if so, how can this fuel smarter apps and insights?

What Are Crypto APIs and Why Are They Important?

A crypto API (Application Programming Interface) is a set of endpoints and protocols that connect applications to blockchain networks or data aggregators. Instead of directly querying nodes or parsing blocks, developers can access a stream of blockchain-related data in real time via these APIs.

APIs abstract away the technical complexity of on-chain data, providing accessible methods for retrieving token prices, wallet balances, transaction histories, smart contract events, NFT metadata, and DeFi protocol information. This simplifies everything from price tracking to building sophisticated crypto apps and analytics dashboards.

Accurate, up-to-date blockchain data is the foundation for researching NFT projects, assessing DeFi protocol health, and even powering AI agents tasked with blockchain tasks. Leading crypto APIs provide developers with high-level access, so they can focus on building features instead of managing blockchain infrastructure.

NFT Data Accessible Through Crypto APIs

Non-fungible tokens (NFTs) have unique data structures, including metadata, ownership history, royalty rules, and underlying assets. Many modern crypto APIs cater to NFT-specific data retrieval, facilitating applications like NFT wallets, galleries, marketplaces, and analytics platforms.

  • Ownership & provenance: APIs can fetch real-time and historical information about who owns a given NFT, how ownership has changed, and related on-chain transactions.
  • Metadata and imagery: Developers retrieve NFT metadata (e.g., images, attributes) directly from smart contracts or token URIs, often with additional caching for speed.
  • Marketplace integration: Some APIs aggregate current and past prices, listing details, and sales volumes from top NFT marketplaces.
  • Activity monitoring: Event endpoints allow tracking of NFT mints, transfers, and burns across chains.

Popular NFT API providers—such as OpenSea API, Alchemy, Moralis, and Token Metrics—differ in their supported blockchains, rate limits, and depth of metadata. When selecting a crypto API for NFTs, compare which standards are supported (ERC-721, ERC-1155, etc.), ease of integration, and the richness of returned data.

How Crypto APIs Handle DeFi Protocol and Market Data

Decentralized finance (DeFi) relies on composable smart contracts driving lending, trading, yield farming, liquid staking, and more. Accessing accurate, real-time DeFi data—such as TVL (total value locked), pool balances, lending/borrowing rates, or DEX trade history—is critical for both app builders and researchers.

Leading crypto APIs now offer endpoints dedicated to:

  • Protocol statistics: TVL figures, liquidity pool compositions, APYs, token emissions, and reward calculations.
  • Real-time DeFi prices: AMM pool prices, slippage estimates, and historical trade data across major DEXes and aggregators.
  • On-chain governance: Information about DeFi protocol proposals, votes, and upgrade histories.
  • User positions: Individual wallet interactions with DeFi protocols (e.g., collateral, borrowings, farming positions).

APIs such as DeFi Llama, Covalent, and Token Metrics provide advanced DeFi analytics and are popular among platforms that track yields, compare protocols, or automate investment analyses (without providing investment advice). Evaluate the update frequency, supported chains, and the granularity of metrics before integrating a DeFi data API.

Key Benefits and Limitations of Using APIs for NFT and DeFi Data

APIs offer significant advantages for NFT and DeFi development:

  • Rapid access to up-to-date blockchain information
  • Abstraction from blockchain-specific quirks and node maintenance
  • Ready-to-integrate endpoints for user-facing dashboards or backend analytics
  • Support for multi-chain or cross-standard data in a unified interface

However, there are trade-offs:

  • Rate limiting can throttle large-scale data pulls.
  • Data freshness may lag behind direct node access on some platforms.
  • APIs sometimes lack coverage for emerging standards or new protocols.

Choosing the right API for NFTs or DeFi often means balancing coverage, performance, cost, and community support. For applications that require the most recent or comprehensive data, combining multiple APIs or supplementing with direct on-chain queries might be needed. Developers should review documentation and test endpoints with sample queries before full integration.

Real-World Use Cases: NFT and DeFi Applications Powered by APIs

Several innovative crypto products rely on powerful APIs to fetch and process NFT and DeFi data:

  • Portfolio dashboards: Aggregating NFT holdings, DeFi investments, token balances, and performance metrics into a single user interface.
  • Market analytics tools: Analyzing trends in NFT sales, DeFi protocol growth, or liquidity volatility across multiple chains and protocols.
  • AI-driven agents: Enabling bots that track NFT listings, monitor DeFi yields, or automate position rebalancing using real-time data streams (without human input).
  • Compliance and reporting systems: Automatically tracking on-chain ownership, yields, or trade histories for tax and regulatory requirements.

Whether for wallet apps, analytical dashboards, or next-gen AI-driven crypto agents, high-quality data APIs serve as the backbone for reliable and scalable blockchain solutions.

How Crypto APIs Streamline Tax Reporting for Digital Assets

Token Metrics Team
6
MIN

For active crypto traders and digital asset holders, the yearly ritual of tax reporting can be complicated and stressful. Each wallet, exchange, and blockchain interacts in ways that fragment your transaction data, making accurate reporting a daunting task. As crypto adoption spreads, can crypto APIs simplify this process and help ensure accurate, timely tax compliance?

What Are Crypto APIs and Why Do They Matter?

APIs, or Application Programming Interfaces, are digital gateways that allow software applications to communicate with one another. In the cryptocurrency world, crypto APIs connect apps, platforms, and users to real-time blockchain data, exchange information, and transaction histories. Major exchanges, wallets, and analytics providers offer APIs so users can access their data programmatically.

For tax reporting, this connection is critical. Crypto APIs enable retrieval of:

  • All wallet and exchange transactions—including buys, sells, transfers, and staking rewards
  • Historical price data for each asset
  • Incoming and outgoing token flows (even across multiple blockchains)
  • Unique identifiers for each transaction

This direct access ensures users and accounting tools get the most accurate, comprehensive data possible, setting the foundation for compliant tax reporting.

How Crypto APIs Support Tax Reporting

Crypto tax liabilities are determined by tracking each crypto transaction throughout the tax year—across wallets, exchanges, blockchains, and DeFi protocols. Each step must be captured: acquisitions, sales, conversions, airdrops, rewards, and sometimes even failed transactions. Manually gathering this information often leads to errors and omissions.

Crypto APIs automate much of this process:

  • Transaction Aggregation: APIs fetch transaction histories from exchanges and wallets, eliminating manual downloads or spreadsheet entries.
  • Historical Pricing: APIs deliver price data at the exact moments of each transaction, enabling accurate capital gains/loss calculations.
  • Multi-Asset, Multi-Chain Support: API integrations can bring together Bitcoin, Ethereum, altcoins, and tokens from various blockchains for consolidated reporting.
  • Tax Form Generation: Some tax tools leverage APIs to automatically fill IRS forms such as 8949 or country-specific equivalents.

By automating data retrieval and normalization, APIs reduce human error and relieve the tedium of manual tracking, increasing the likelihood of accurate and compliant reporting.

Types of Crypto APIs Used for Taxation

Various crypto APIs play roles in tax calculation and compliance workflows. Their capabilities can be grouped into several categories:

  • Exchange APIs: Provide read-only access to trade history, transfers, and account balances from centralized trading platforms.
  • Wallet APIs: Extract on-chain transactions, including self-custodied wallets and hardware devices, for full account tracing.
  • Blockchain Data APIs: Parse data from the blockchain itself for assets or platforms not covered by common wallets/exchanges.
  • Price & Market Data APIs: Supply pricing at specific timestamps, essential for tax-lot and fair market value calculations.
  • Analytics & Reporting APIs: Common with crypto tax software, these deliver formatted tax reports, error warnings, and suggestion workflows.

Leading crypto tax tools integrate one or more of these API types to connect your accounts and gather all the necessary information for reporting.

Choosing the Right Crypto API for Your Tax Needs

No single crypto API covers every trading platform, blockchain, or asset. When selecting an API—or a tax tool that integrates APIs—consider these factors:

  • Covers All Your Sources: Check if the API (or tools that use it) supports all the exchanges, wallets, and blockchains you’ve used in the tax year.
  • Data Completeness: Ensure the API delivers granular transaction details (timestamps, fees, asset IDs, etc.) for accurate gain/loss calculations.
  • Reliability & Security: Look for established providers with a track record of uptime and compliant data handling practices.
  • Automation & Scalability: If you’re an active trader or institutional user, prioritize APIs offering automation, bulk data retrieval, and developer support.
  • Integration with Tax Software: Using a tax platform with strong API integrations with your coins and exchanges can simplify everything—from import to tax form generation.

Popular crypto tax platforms often act as aggregators, using APIs from multiple sources to ensure complete data capture and reporting accuracy. Advanced APIs—even AI-powered ones like those from Token Metrics—can also provide on-chain analysis and insights that may help proactively monitor tax impacts throughout the year.

A Closer Look at Using Crypto APIs for Tax Reporting

Let’s walk through how APIs typically fit into crypto tax workflows:

  1. Connect Accounts and Wallets: Using API keys (often read-only), you link your exchanges, wallets, and blockchains to your chosen tax tool.
  2. Sync and Import Transactions: The tool pulls transaction histories via APIs, consolidating buys, sales, deposits, withdrawals, airdrops, NFTs, and more.
  3. Fetch On-Chain and Historical Prices: Market data APIs retrieve price history at the exact transaction times.
  4. Classify Transactions: Using smart algorithms (sometimes AI-driven), the tool/utility tags income, capital gains, staking rewards, gifting, or transfers.
  5. Generate Tax Reports: With everything categorized, software can generate the tax forms, appendices, or summaries you’ll need for digital asset tax reporting.

This streamlined approach saves time, reduces costly mistakes, and, crucially, helps create a paper trail that stands up to tax authority scrutiny. For high-volume traders or those moving assets across multiple platforms, crypto APIs are increasingly seen as a necessity—not just a convenience.

FAQ: Can I Use Crypto APIs for Tax Reporting?

What info do crypto APIs provide for tax reporting?

Crypto APIs can deliver transaction histories, account balances, historical pricing, and details such as gas fees and blockchain-specific data, enabling accurate calculation of gains, losses, and income for tax filing.

Are crypto API integrations secure for tax purposes?

Most reputable APIs utilize read-only permissions, so users can’t withdraw or trade with connected accounts. Always use API keys securely, with platforms that prioritize user data privacy and security.

Can I use APIs for every type of crypto asset?

While many APIs cover major coins and blockchains, full support for NFTs, DeFi protocols, and newer tokens may vary. Check compatibility with your holdings before relying exclusively on APIs for reporting.

Do crypto tax platforms use APIs or manual imports?

Most modern crypto tax platforms offer both—APIs for automated data syncing and manual CSV/Excel uploads as a fallback, ensuring coverage when API connectivity isn’t available for a particular service.

Will using crypto APIs make me compliant with tax laws?

APIs streamline data collection but do not ensure compliance by themselves. Users must ensure all transactions are captured, accurately reported, and filed according to local reporting requirements.
