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.

Fundamental Grade API: Invest with Conviction Using Real Project Signals

Sam Monac
7 min
MIN

Most traders chase price action; Fundamental Grade API helps you see the business behind the token—community traction, tokenomics design, exchange presence, VC signals, and DeFi health—consolidated into one score you can query in code. In a few minutes, you’ll fetch Fundamental Grade, render it in your product, and ship a due-diligence UX that drives trust. Start by grabbing your key at the Get API Key page, Run Hello-TM to verify your first call, then Clone a Template to go live fast.

‍

What You’ll Build in 2 Minutes

  • A minimal script to fetch Fundamental Grade from /v2/fundamental-grade for any symbol (e.g., BTC).

  • Optional curl to smoke-test your key in seconds.

  • A drop-in pattern to display the grade + key drivers in dashboards, screeners, and research tools.

  • Endpoints to consider next: /v2/tm-grade (technical/sentiment/momentum), /v2/price-prediction (scenario planning), /v2/resistance-support (risk levels), /v2/quantmetrics (risk/return stats).

Why This Matters

Beyond price, toward quality. Markets are noisy—hype rises and fades. Fundamental Grade consolidates hard-to-track signals (community growth, token distribution, liquidity venues, investor quality, DeFi integrations) into a clear, comparable score. You get a fast “is this worth time and capital?” answer for screening, allocation, and monitoring.

Build trust into your product. Whether you run an investor terminal, exchange research tab, or a portfolio tool, Fundamental Grade lets users justify positions. Pair it with TM Grade or Quantmetrics for a balanced picture: what to buy (fundamentals) and when to act (signals/levels).

Where to Find 

The Fundamental Grade is easily accessible in the top right of the API Reference. Grab the cURL request for seamless access!

👉 Ready to build? Get API Key • Run Hello-TM • Clone a Template

Live Demo & Templates

  • Due-Diligence Token Page: Show Fundamental Grade with a component breakdown (community, tokenomics, exchange presence, VC, DeFi).

  • Screener/Ranker: Sort by Fundamental Grade, add market-cap bands, and flag “rising fundamentals” week-over-week.

  • Allocation Dashboard: Combine Fundamental Grade with TM Grade and Quantmetrics for resilient portfolio construction.

Kick off from our quickstarts—fork a dashboard or screener template, plug your key, and deploy. If you’re new here, Run Hello-TM first to confirm your environment, then scale into product features. When you outgrow the free tier, compare API plans.

How It Works (Under the Hood)

Fundamental Grade aggregates multiple project-quality signals into a normalized score and label (e.g., Strong / Average / Weak). Typical sub-signals include:

  • Community: momentum across channels (dev activity/user traction signals where applicable).

  • Tokenomics: supply schedule, distribution, unlock dynamics, incentives.

  • Exchange Presence: venue coverage, depth/liquidity proxies.

  • VC/Investor Signals: quality/durability of backing and ecosystem support.

  • DeFi Health: integrations, TVL context, composability footprint.

At query time, you call /v2/fundamental-grade with a symbol; responses include the overall score plus component scores you can visualize. For dashboards with many assets, batch fetches and short-TTL caching keep pages responsive. If you push alerts (e.g., “Fundamental Grade upgraded”), prefer webhooks or queued jobs to avoid hammering the API.

Production Checklist

  • Rate limits: Know plan caps; add client throttling and request queues.

  • Retries/backoff: Exponential backoff + jitter; surface actionable error messages.

  • Idempotency: Prevent duplicate downstream actions on retried calls.

  • Caching: Use memory/Redis/KV with short TTLs; pre-warm popular symbols.

  • Webhooks & jobs: For alerts, use signed webhooks or scheduled jobs; log delivery outcomes.

  • Pagination/Bulk: When covering many tokens, paginate or process in batches.

  • Error catalog: Map 4xx/5xx to user-visible fixes; log request IDs.

  • Observability: Track p95/p99 and error rate per endpoint; alert on spikes.

  • Security: Keep API keys in secrets managers; rotate regularly.

Use Cases & Patterns

  • Screener Maker: Rank tokens by Fundamental Grade, filter by market cap/sector, and add “rising fundamentals” badges for discovery.

  • Dashboard Builder: On each token page, show the headline grade with a component chart; link to methodology for transparency.

  • Research & PM Tools: Flag downgrades/upgrades to prompt re-evaluation; attach notes to component changes (e.g., DeFi health drop).

  • Allocator / Risk: Require a minimum Fundamental Grade before inclusion; rebalance only when grade crosses thresholds.

  • Community/Discord: Post weekly upgrades as digest messages with links back to your app.

FAQs

1) What does the Fundamental Grade API return?
A JSON payload with the overall score/grade plus component scores (e.g., community, tokenomics, exchange presence, VC backing, DeFi health) and timestamps. Use the overall grade for ranking and component scores for explanations.

2) How fast is the endpoint? Do you publish SLOs?
The API is engineered for predictable latency. For high-traffic dashboards, add short-TTL caching and batch requests; for alerts, use jobs/webhooks to minimize round-trips.

3) Can I combine Fundamental Grade with TM Grade or signals?
Yes. A common pattern is Fundamental Grade for quality filter + TM Grade for technical/sentiment context + Trading Signals for timing and Support/Resistance for risk placement.

4) How “accurate” is the grade?
It’s an opinionated synthesis of multiple inputs—not financial advice. Historical studies can inform usage, but past performance doesn’t guarantee future results. Always layer risk management and testing.

5) Do you offer SDKs and examples?
You can use REST directly (see JS/Python above). The docs include quickstarts, Postman, and ready-to-clone templates—start with Run Hello-TM.

6) Polling vs webhooks for fundamentals updates?
For UI pages, cached polling works well. For event-style notifications (upgrades/downgrades), prefer webhooks or scheduled jobs to avoid spiky traffic.

7) What about pricing, limits, and enterprise SLAs?
Begin free and scale as you grow. See API plans for allowances; enterprise SLAs and support are available—contact us.

TM Grade API: Turn Market Noise into One Clear Signal

Sam Monac
7 min
MIN

Cluttered charts and whipsaw price action make it hard to act with conviction. The TM Grade API turns that noise into a single, opinionated signal you can build on—ideal for trading bots, dashboards, and research tools. In this guide, you’ll pull TM Grade in code, see how it powers products, and ship something useful in minutes. Start with the Get API Key, then Run Hello-TM in the docs and Clone a Template to go live fast.

‍

What You’ll Build in 2 Minutes

  • A minimal script that fetches TM Grade from /v2/tm-grade for a given token (e.g., BTC).

  • An optional curl call to test the endpoint instantly.

  • A path to production using a copy-ready template (bot, dashboard, or screener).

  • (Mentioned endpoints you can add next: /v2/trading-signals, /v2/price-prediction, /v2/resistance-support.)

Why This Matters

One score, clear decision. TM Grade distills technicals, sentiment, and momentum into a single, interpretable value from Strong Sell → Strong Buy. Instead of juggling indicators, you get an opinionated, trade-ready signal you can rank, alert on, and route into strategies.

Built for builders. Developers integrate TM Grade to filter universes, power dashboards, or trigger bots—with predictable performance and a schema designed for programmatic use. Pair it with webhooks and caching to slash latency and polling costs.

Where to Find 

In the top right of the API Reference you can find the curl request for your desired language. This is what you can use to access the TM Grade endpoint. 

‍

👉 Ready to go further? Get API Key • Run Hello-TM 

Live Demo & Templates

  • Trading Bot Starter: Use TM Grade to filter a trade universe and gate entries with your own risk rules.

  • Dashboard Token Page: Show TM Grade alongside price, S/R levels, and signals for instant context.

  • Screener/Leaderboard: Rank tokens by TM Grade and highlight movers.

You can start from our quickstarts in the docs—fork, plug your key, and deploy in minutes. Run Hello-TM to see the first call succeed, then scale into a bot or dashboard. When you’re ready for higher limits, compare API plans.

How It Works (Under the Hood)

TM Grade blends multiple evidence streams—technical momentum, market structure, sentiment, and other model inputs—into a single normalized score (e.g., 0–100) and a label (Strong Sell to Strong Buy). This opinionated synthesis is what separates TM Grade from raw market data: it’s designed to be actionable.

Polling vs webhooks. For screens and dashboards, lightweight polling (or cached fetches) is fine. For trading agents and alerting, use webhooks or short polling with backoff and caching to cut latency and call volume. Combine TM Grade with endpoints like /v2/trading-signals for timing or /v2/resistance-support for risk placement.

Production Checklist

  • Rate limits: Know your plan caps; add client-side throttling.

  • Retries/backoff: Exponential backoff + jitter; avoid thundering herd.

  • Idempotency: Ensure repeated calls don’t double-execute downstream actions.

  • Caching: Short-TTL cache for reads (memory/Redis/KV); ETag if available.

  • Webhooks: Use signatures/secret validation; queue and retry on failure.

  • Pagination/Bulk: If fetching many symbols, batch requests with pagination.

  • Error catalog: Map 4xx/5xx to user-visible fixes; log status, payload, and request ID.

  • Observability: Track p95/p99 latency and error rate per endpoint; alert on spikes.

Use Cases & Patterns

  • Bot Builder (Headless): Filter tradable universes to Strong Buy/Buy, then confirm with timing from /v2/trading-signals before placing orders.

  • Dashboard Builder (Product): Show TM Grade on token pages with badges, color states, and last-updated timestamps; add S/R lines for context.

  • Screener Maker (Lightweight Tools): Build a Top-N by TM Grade list with sector filters; cache results and add one-click alerts.

  • Research/Allocation: Surface grade trends (rising/falling) to inform rebalances and risk budgets.

  • Community/Discord: Post grade changes to channels; rate-limit announcements and link to token detail views.

Next Steps

  • Get API Key — start free and generate a key in seconds.

  • Run Hello-TM — verify your first successful call.

  • Clone a Template — ship a bot, dashboard, or screener today.

  • Watch the demo: VIDEO_URL_HERE

  • Compare plans: When you’re ready to scale, review API plans.
