Crypto is a huge industry that covers everything from technology to currencies, and even how it's taxed. First off, you don’t owe taxes on crypto if you’re merely “hodling,” as aficionados would say. But if you’ve gained any income from crypto in a financial  year — either from staking, lending, or selling — you may owe taxes on the proceeds.

The IRS treats all cryptocurrencies as capital assets, and that means you owe capital gains taxes when they’re sold at a profit. This is exactly what happens when you sell more traditional securities, like stocks or funds, for a gain.

Let’s say you bought $1,000 in Ethereum and then sold the coins later for $1,600. You’ll need to report that $600 capital gain on your taxes. The taxes you owe depend on the length of time you held your coins.

If you held your ETH for one year or less, the $600 profit would be taxed as a short-term capital gain. Short-term capital gains are taxed the same as regular income — and that means your adjusted gross income (AGI) determines the tax rate you pay.

Federal income tax brackets top out at a rate of 37%. To be in the top bracket for 2023, you would need to make $578,126 or more as a single filer.

In this article, we'll discuss some of the basics of how crypto is taxed. We'll also go through tips for saving tax when dealing with cryptocurrencies.

Crypto Is Taxed in Two Ways

There are two ways to tax crypto: as property and as a commodity.

Property taxes apply when you buy, sell or trade cryptocurrencies. Commodity taxes apply if you use your crypto to pay for goods or services — for example buying things from Amazon with Bitcoin.

How Is Crypto Taxed?

Cryptocurrency is taxed as property. This means that you can claim the fair market value of your cryptocurrency in the year it was acquired and later sold or exchanged for other cryptocurrencies, fiat currency, or goods/services.

Cryptocurrency is not taxed as a currency. The income tax treatment of cryptocurrencies varies depending on whether you're purchasing them through an exchange (such as Coinbase), mining them yourself, or earning them through another activity like freelance work.

If you mine coins yourself, they are considered capital gains and reported on Schedule D with other business assets held at fair market value when sold off at their peak price during 2017-2018; however, if they were mined during 2014-2015 then they would be treated like ordinary income instead since there weren't any real-world uses for this type of digital money yet back then!

Cryptocurrencies may be considered business income under Section 199A(a)(1)(B) which exempts certain trades done by non-corporate entities from taxation but only if those trades meet specific criteria such as being done "for consideration" (defined below). In order for something to qualify under section 199A(a)(1)(B), two conditions must be met: 1) You must have received payment/gains derived from selling goods/services 2) Those gains were derived from selling goods/services that had been produced either domestically located within United States territory OR imported into United States territory AND THEN EXPORTED OUTSIDE OF US TERRITORY.

What Happens if You Don’t Report Cryptocurrency on Taxes?

If you don't report cryptocurrency on taxes, you could face a penalty. This can range from a fine to jail time for tax evasion and other criminal charges, depending on the laws in your country. In addition to facing criminal penalties for failing to report crypto income, there are also some civil penalties that apply if you don't pay back taxes owed from crypto-based income:

  • Interest accrued on any unpaid taxes owed by late payment
  • Amounts owed in restitution (if applicable)

Tips to Save Tax on Your Crypto Gains

  • Keep a record of your crypto transactions.
  • Use a crypto tax software to calculate your taxes.
  • Invest in tax-advantaged retirement accounts, such as an employer-sponsored 401(k) or traditional IRA. If you don't have enough money saved up from working, consider opening one of these accounts through an online broker like Charles Schwab or Vanguard — and then use it to buy Bitcoin or other cryptocurrencies! You can also set up a self-directed IRA so that you control how the funds are invested and who uses them for expenses like traveling outside the country (taxes will apply).

Like any other investment, the IRS will demand a share of your crypto profits, unless you follow certain tax strategies.

The IRS is aware of cryptocurrency, and it's looking for you. Since the IRS has been auditing cryptocurrency investors and issuing 1099-K forms to individuals who have made taxable gains from their crypto investments, it's clear that they know something about cryptocurrencies.

The IRS has also been targeting exchanges and other businesses involved with cryptocurrency trading or holding cryptocurrencies themselves. If you're an exchange and don't report your income correctly, this could result in hefty penalties from the IRS — and even more serious consequences if you're found guilty of evading taxes altogether!

Conclusion

Crypto is a hot topic, with many people wondering how they should use it and report it on taxes. The IRS says that crypto is taxable as property or capital gains, depending on the type of crypto you own and what you do with it after receiving your profits. You can also report crypto-based income for other tax purposes (such as self-employment), but only if you have documentation to prove when the event occurred and how much income was generated from these transactions (which may be difficult).

What Is an API? A Practical Guide

Token Metrics Team

APIs power modern software, enabling apps to share data, automate workflows, and connect services. Whether you use a weather feed, social login, or a crypto data stream, understanding what an API is helps you design, evaluate, and integrate digital products more effectively.

What is an API?

An API, or application programming interface, is a defined set of rules that lets one software system communicate with another. At its simplest, an API specifies how requests are structured, which methods are available, and how responses are returned. Developers use APIs to access functionality or data without needing to know internal implementation details.

Think of an API as a contract: it tells you the inputs required, the outputs to expect, and any constraints or error cases. This separation of concerns enables modular development, third-party integrations, and scalable ecosystems.

How APIs work: components and protocols

Most modern APIs expose endpoints—URLs or functions—that accept requests and return responses. Key components include:

  • Endpoints: Specific URLs or methods that provide a capability or data set.
  • Methods: Actions such as GET, POST, PUT, DELETE in HTTP-based APIs.
  • Payloads: Structured request and response bodies (commonly JSON).
  • Authentication: Keys, tokens, or OAuth flows that control access.
  • Rate limits: Constraints on usage to protect service availability.

Different protocols influence API behavior. REST uses resource-oriented URLs and standard HTTP verbs; GraphQL offers flexible queries over a single endpoint; gRPC supports high-performance, binary-protocol calls suitable for microservices. Choosing a protocol depends on latency requirements, payload complexity, and developer experience.

Common API use cases: web, mobile, and crypto

APIs underpin many real-world scenarios:

  • Web and mobile apps: Fetching user data, processing payments, or embedding maps.
  • Microservices: Internal APIs let services communicate within distributed systems.
  • Third-party integrations: Social logins, analytics platforms, and CRM synchronization.
  • Data feeds and analytics: Market prices, news, and on-chain metrics delivered via APIs enable automated research pipelines.

In the crypto space, APIs expose on-chain data, aggregated price feeds, and derived indicators. Developers can combine multiple APIs to build dashboards, bots, or AI research agents. When evaluating crypto APIs, consider latency, historical coverage, and data provenance.

For example, research teams often use AI-driven platforms to enrich raw feeds with signals and insights. One such platform, Token Metrics, integrates data and models to support comparative analysis and idea generation.

Choosing and evaluating APIs: practical criteria

When selecting an API, use a structured evaluation framework:

  1. Functionality — Does the API provide required endpoints and historical coverage?
  2. Reliability — Look at uptime SLAs, error rates, and redundancy.
  3. Data quality — Verify schemas, sample payloads, and provenance.
  4. Performance — Measure latency and throughput relevant to your use case.
  5. Security and access control — Inspect auth models, encryption, and rate limits.
  6. Costs and licensing — Understand pricing tiers and any usage restrictions.
  7. Documentation and SDKs — Clear docs and client libraries speed integration.

Combine quantitative tests (latency, success rate) with qualitative checks (docs clarity, community support). For complex builds, sandbox environments and trial keys help validate assumptions before full integration.

FAQ: What is an API?

An API (application programming interface) is a specification that allows software systems to request and exchange data or trigger actions without exposing internal code. It defines endpoints, parameters, and response formats.

FAQ: How is a REST API different from GraphQL?

REST organizes interactions around resources and uses multiple endpoints; clients request predefined payloads. GraphQL exposes a single endpoint where clients define the shape of the response, reducing over- or under-fetching in many scenarios.

FAQ: What security measures should APIs use?

Common measures include HTTPS/TLS, API keys or OAuth tokens, rate limiting, input validation, and monitoring for unusual patterns. Secure defaults and least-privilege access reduce attack surface.

FAQ: Can I use public APIs for production applications?

Many public APIs are production-ready if they provide SLAs, reliable documentation, and appropriate rate limits. Validate through trials and consider failover strategies and caching for resilience.

FAQ: How do APIs support automation and AI?

APIs provide structured, machine-readable data and endpoints that automation tools and AI agents can call programmatically. Combining APIs with model inference enables workflows like signal generation, backtesting, and report automation.

FAQ: What are rate limits and why do they matter?

Rate limits control how many requests a client can make in a time window to ensure fair usage and protect service availability. Exceeding limits typically leads to temporary blocking or throttled responses.

APIs Explained: What They Are and How They Work

APIs power much of the software you use daily — from fetching weather data in a mobile app to connecting decentralized exchanges to analytics dashboards. If youve ever wondered what an API is, why developers rely on them, and how they shape the modern web and crypto ecosystems, this guide breaks down the core concepts, common patterns, and practical steps to evaluate and use APIs effectively.

What is an API?

An API (Application Programming Interface) is a set of rules and protocols that lets different software components communicate. At a high level, an API defines how a caller requests data or functionality and how the provider responds. APIs abstract implementation details so developers can use capabilities — like retrieving market prices or sending messages — without needing to understand the providers internals.

Think of an API as a contract: a client sends a request in a specified format, and the service returns structured responses. Contracts can include endpoints, expected parameters, authentication methods, rate limits, error codes, and data schemas.

How APIs Work — a Technical Overview

Most modern APIs use web protocols (HTTP/HTTPS) and standard formats such as JSON. A typical request cycle looks like this:

  1. Client constructs a request URL or payload, optionally including authentication credentials (API key, OAuth token).
  2. Client sends the request to an API endpoint using a method like GET, POST, PUT, or DELETE.
  3. Server validates the request, applies business logic, and returns a response with data or an error code.
  4. Client parses the response and integrates it into the application.

APIs can enforce rate limits, usage quotas, and schema validation. In production systems, observability (logging, traces, metrics) and secure transport (TLS) are standard to ensure reliability and confidentiality.

Types of APIs & Common Patterns

APIs come in several styles, each with trade-offs:

  • REST (Representational State Transfer): Resource-oriented, uses HTTP verbs and status codes; widely adopted and easy to cache.
  • GraphQL: Lets clients request exactly the fields they need; reduces over-fetching but increases server complexity.
  • gRPC / RPC: Binary protocol for high-performance communication, often used for internal microservices.
  • Webhooks: Server-initiated callbacks to notify clients of events, useful for real-time notifications.

In crypto and finance, youll see specialized APIs that provide order book data, historical trades, on-chain events, and wallet actions. Public APIs are accessible with minimal barriers, while private APIs require credentials and stricter access controls.

How to Evaluate and Use an API (Practical Steps)

Choosing and integrating an API involves technical, operational, and security considerations. A concise evaluation framework:

  1. Functionality: Does the API provide the endpoints and data formats you need? Review sample responses and SDKs.
  2. Performance & Reliability: Check latency, uptime SLA, and historical performance metrics if available.
  3. Security: Verify authentication schemes, encryption, data retention policies, and whether the provider supports IP allowlists or role-based access.
  4. Costs & Rate Limits: Understand free tier limits, pricing per request, and billing granularity to budget accordingly.
  5. Documentation & Support: High-quality docs, examples, and community support accelerate integration and troubleshooting.

When prototyping, use tools like Postman or curl to explore endpoints. Automate tests to validate responses and simulate rate limits. For production, incorporate retries with exponential backoff, circuit breakers, and monitoring to handle transient failures gracefully.

AI-driven research tools can speed analysis of API datasets by surfacing patterns and summarizing changes. For instance, applications that combine market or on-chain APIs with AI models can transform raw feeds into signals or structured insights. An example of a research platform often used for crypto analysis is Token Metrics, which demonstrates how analytics layers can complement API outputs without replacing rigorous technical validation.

FAQ: What is an API?

An API (Application Programming Interface) is a documented way for software components to request services or data from one another. In web contexts, APIs typically expose endpoints over HTTP that return structured data formats such as JSON.

FAQ: How do APIs stay secure?

Common security practices include using HTTPS/TLS, API keys or OAuth for authentication, rate limiting, input validation to prevent injection attacks, and strong access control policies. Regular audits and logging help detect anomalies.

FAQ: Should I use REST or GraphQL?

REST is simple and cache-friendly; GraphQL is flexible for clients that need selective fields. Choose based on client requirements, caching needs, and team familiarity. Both can coexist in larger systems.

FAQ: How do I test an API integration?

Start with manual exploration (Postman, curl), then write automated tests for schema, error handling, rate limit behavior, and performance. Mock external APIs during unit testing and run contract tests during CI/CD.

FAQ: How are APIs used in crypto applications?

Crypto apps use APIs to fetch market prices, execute orders, read on-chain data, and stream events. Reliable APIs reduce complexity for developers but require careful handling of latency, consistency, and security.

APIs Explained: How They Power Software and Crypto

Token Metrics Team

APIs are the invisible connectors that let apps talk to each other. Whether you’re loading a weather widget, pulling crypto prices into a dashboard, or integrating an AI model, understanding how APIs work helps you design, evaluate, and secure systems that depend on reliable data.

What is an API?

An API—Application Programming Interface—is a clearly defined set of rules and contracts that lets one software program request services or data from another. At its core an API specifies how to format requests, what endpoints are available, what parameters are accepted, and how the provider will respond. Think of it as a menu at a restaurant: you pick dishes (requests), the kitchen prepares them (the service), and the waiter returns your order (the response) without exposing internal cooking processes.

APIs exist at many levels: operating system APIs expose filesystem and device operations, library APIs expose functions and classes, and web APIs expose remote services across networks. In modern web and mobile development, "API" often refers to HTTP-based interfaces that return structured data like JSON or XML.

How APIs Work: Requests, Responses, and Data Formats

Most web APIs operate on a request–response model. A client issues a request to a defined endpoint using a method (GET, POST, PUT, DELETE), optionally supplying parameters or a payload. The server processes the request and returns a response with a status code and body.

Key technical elements to understand:

  • Endpoints: URLs that map to resources or actions (e.g., /v1/prices).
  • HTTP Methods: Semantic actions (GET = read, POST = create, etc.).
  • Status Codes: 2xx successes, 4xx client errors, 5xx server errors.
  • Data Formats: JSON is ubiquitous for APIs due to its simplicity; XML and protobufs appear in legacy or high-performance systems.
  • Authentication & Authorization: API keys, OAuth tokens, JWTs, and mTLS govern who can access which endpoints.
  • Rate Limits & Quotas: Providers throttle requests to protect infrastructure and ensure fair use.

Real-time APIs may use WebSockets or server-sent events for streaming data rather than repeated HTTP polling. Designing for observability—clear logs, metrics, and error messages—improves operational resilience.

Common API Types and Protocols

Different projects require different API styles. Choosing a style depends on latency, flexibility, compatibility, and developer experience needs.

  • REST: Representational State Transfer emphasizes resources and standard HTTP verbs. RESTful APIs are easy to cache and widely supported.
  • GraphQL: Clients request exactly the fields they need in a single query, reducing over-fetching. GraphQL adds flexibility but requires careful performance tooling.
  • SOAP: An XML-heavy protocol that offers strict contracts and built-in standards for security and transactions; common in enterprise systems.
  • gRPC / Protobuf: High-performance RPC frameworks for microservices with compact binary payloads and strict typing.
  • Webhooks: Reverse-style APIs where a service pushes events to your endpoint, useful for near-real-time notifications without polling.

APIs are often packaged with SDKs for languages like Python, JavaScript, or Go to simplify integration. Documentation, example requests, and interactive consoles dramatically improve adoption.

APIs in Crypto and AI: Use Cases and Considerations

APIs are central to crypto and AI ecosystems. In crypto, APIs provide market data (prices, order books), on-chain insights (transaction history, token balances), and node RPC endpoints for smart contract interaction. AI systems use APIs to host inference endpoints, orchestrate models, and integrate external data sources for context.

Key considerations when selecting or building APIs for these domains:

  • Data Accuracy: In finance and blockchain, stale or inconsistent data can lead to incorrect analysis. Verify timestamps, aggregation logic, and reconciliation methods.
  • Latency and Throughput: Trading or real-time analytics may require low-latency streaming or websocket feeds instead of periodic REST calls.
  • Security: Protect API keys, enforce least privilege, use encrypted transport (HTTPS/TLS), and monitor for anomalous request patterns.
  • Reliability: Redundancy, caching strategies, and graceful degradation help maintain service if a provider faces outages.
  • Compliance & Privacy: Understand data retention, user privacy, and jurisdictional constraints when handling labeled or personal data.

Tools like Token Metrics combine market and on-chain data with AI to support research workflows that depend on reliable API feeds and model-driven signals.

What is the difference between REST and GraphQL?

REST exposes multiple endpoints representing resources; clients may need several calls to assemble data. GraphQL exposes a single query endpoint where clients request precisely the fields they need. REST is simpler to cache; GraphQL offers flexibility but can require extra server-side tooling to manage complex queries and performance.

How do I secure an API key?

Never embed keys in client-side code. Store keys in secure server environments or secrets managers, rotate keys periodically, apply scope and rate limits, and monitor usage. Implementing short-lived tokens and IP whitelisting adds protection for sensitive endpoints.

When should I use webhooks instead of polling?

Use webhooks when you need event-driven, near-real-time notifications and want to avoid the overhead of frequent polling. Webhooks push updates to your endpoint, but require you to handle retries, verify payload signatures, and secure the receiving endpoint.

Can I build an API for my blockchain node?

Yes. Many projects wrap node RPCs with REST or GraphQL layers to standardize queries and add caching, rate limiting, and enrichment (e.g., token metadata). Be mindful of node sync status, resource consumption, and privacy considerations when exposing node endpoints.

How do I evaluate an API provider?

Assess API documentation quality, uptime/SLAs, latency, data freshness, authentication options, and support channels. Request sample data, test in sandbox environments, and compare pricing with expected usage. For crypto use cases, verify on-chain data coverage and reconciliation methods.
