In today's digital asset ecosystem, Application Programming Interfaces, or APIs, are the unsung heroes enabling everything from cryptocurrency wallets to trading bots. Whether you're a developer building for Web3 or a curious user interested in how your exchange functions, understanding how crypto APIs work is essential

    What Is a Crypto API?

    A crypto API is a set of programming instructions and standards that allow software applications to communicate with cryptocurrency services. These services may include wallet functions, price feeds, trading engines, exchange platforms, and blockchain networks. By using a crypto API, developers can automate access to real-time market data or execute trades on behalf of users without manually interacting with each platform.

    For instance, the Token Metrics API provides structured access to cryptocurrency ratings, analytics, and other data to help teams build intelligent applications.

    Types of Crypto APIs

    There are several categories of APIs in the cryptocurrency landscape, each with different capabilities and use cases:


       

       

       

       

       


    How Crypto APIs Work

    At their core, crypto APIs operate over internet protocols—typically HTTPS—and return data in JSON or XML formats. When an application makes a request to an API endpoint (a specific URL), the server processes the request, fetches the corresponding data or action, and sends a response back.

    For example, a crypto wallet app might call an API endpoint like /v1/account/balance to check a user’s holdings. To ensure security and authorization, many APIs require API keys or OAuth tokens for access. Rate limits are also enforced to prevent server overload.

    Behind the scenes, these APIs interface with various backend systems—blockchains, trading engines, or databases—to fulfill each request in real time or near real time.

    Common Use Cases for Crypto APIs

    Crypto APIs are used across a broad spectrum of applications:

    APIs dramatically reduce time-to-market for developers while enhancing user experience and application efficiency.

    Key Considerations for API Integration

    When integrating a crypto API, consider the following factors:


       

       

       

       

       


    Platforms like the Token Metrics API provide both comprehensive documentation and reliability for developers building AI-powered solutions in crypto.

    AI-Powered Analytics and APIs

    Some of the most powerful crypto APIs now incorporate artificial intelligence and machine learning features. For example, the Token Metrics API facilitates access to predictive models, coin grades, and AI-based price forecasts.

    By embedding these tools into custom apps, users can programmatically tap into advanced analytics, helping refine research workflows and support technical or fundamental analysis. Although these outputs can guide decisions, they should be viewed in a broader context instead of relying exclusively on model predictions.

    Conclusion

    Crypto APIs are critical infrastructure for the entire digital asset industry. From data retrieval and trading automation to blockchain integration and AI-driven analytics, these tools offer immense utility for developers, analysts, and businesses alike. Platforms such as Token Metrics provide not only in-depth crypto research but also API access to empower intelligent applications built on real-time market insights. By understanding how crypto APIs work, users and developers can better navigate the rapidly evolving Web3 landscape.

    Moonshots API: Discover Breakout Tokens Before the Crowd

    Token Metrics Team
    5

    The biggest gains in crypto rarely come from the majors. They come from Moonshots—fast-moving tokens with breakout potential. The Moonshots API surfaces these candidates programmatically so you can rank, alert, and act inside your product. In this guide, you’ll call /v2/moonshots, display a high-signal list with TM Grade and Bullish tags, and wire it into bots, dashboards, or screeners in minutes. Start by grabbing your key at Get API Key, then Run Hello-TM and Clone a Template to ship fast.

    What You’ll Build in 2 Minutes

    Why This Matters

    Discovery that converts. Users want more than price tickers, they want a curated, explainable list of high-potential tokens. The Moonshots API encapsulates multiple signals into a short list designed for exploration, alerts, and watchlists you can monetize.

    Built for builders. The endpoint returns a consistent schema with grade, signal, and context so you can immediately sort, badge, and trigger workflows. With predictable latency and clear filters, you can scale to dashboards, mobile apps, and headless bots without reinventing the discovery pipeline.

    Where to Find The Moonshots API

    The cURL request for the Moonshots endpoint is displayed in the top right of the API Reference. Grab it and start tapping into the potential!

    How It Works (Under the Hood)

    The Moonshots endpoint aggregates a set of evidence—often combining TM Grade, signal state, and momentum/volume context—into a shortlist of breakout candidates. Each row includes a symbol, grade, signal, and timestamp, plus optional reason tags for transparency.

    For UX, a common pattern is: headline list → token detail where you render TM Grade (quality), Trading Signals (timing), Support/Resistance (risk placement), Quantmetrics (risk-adjusted performance), and Price Prediction scenarios. This enables users to understand why a token was flagged and how to act with risk controls.

    Polling vs webhooks. Dashboards typically poll with short-TTL caching. Alerting flows use scheduled jobs or webhooks to smooth traffic and avoid duplicates. Always make notifications idempotent.

    Production Checklist

    Use Cases & Patterns

    Next Steps

    FAQs

    1) What does the Moonshots API return?

    A list of breakout candidates with fields such as symbol, tm_grade, signal (often Bullish/Bearish), optional reason tags, and updated_at. Use it to drive discover tabs, alerts, and watchlists.

    2) How fresh is the list? What about latency/SLOs?

    The endpoint targets predictable latency and timely updates for dashboards and alerts. Use short-TTL caching and queued jobs/webhooks to avoid bursty polling.

    3) How do I use Moonshots in a trading workflow?

    Common stack: Moonshots for discovery, Trading Signals for timing, Support/Resistance for SL/TP, Quantmetrics for sizing, and Price Prediction for scenario context. Always backtest and paper-trade first.

    4) I saw results like “+241%” and a “7.5% average return.” Are these guaranteed?

    No. Any historical results are illustrative and not guarantees of future performance. Markets are risky; use risk management and testing.

    5) Can I filter the Moonshots list?

    Yes—pass parameters like min_grade, signal, and limit (as supported) to tailor to your audience and keep pages fast.

    6) Do you provide SDKs or examples?

    REST works with JavaScript and Python snippets above. Docs include quickstarts, Postman collections, and templates—start with Run Hello-TM.

    7) Pricing, limits, and enterprise SLAs?

    Begin free and scale up. See API plans for rate limits and enterprise options.

    Support and Resistance API: Auto-Calculate Smart Levels for Better Trades

    Token Metrics Team
    4

    Most traders still draw lines by hand in TradingView. The support and resistance API from Token Metrics auto-calculates clean support and resistance levels from one request, so your dashboard, bot, or alerts can react instantly. In minutes, you’ll call /v2/resistance-support, render actionable levels for any token, and wire them into stops, targets, or notifications. Start by grabbing your key on Get API Key, then Run Hello-TM and Clone a Template to ship a production-ready feature fast.

    What You’ll Build in 2 Minutes

    A minimal script that fetches Support/Resistance via /v2/resistance-support for a symbol (e.g., BTC, SOL).

    • A one-liner curl to smoke-test your key.
    • A UI pattern to display nearest support, nearest resistance, level strength, and last updated time.

    Next Endpoints to add

    • /v2/trading-signals (entries/exits)
    • /v2/hourly-trading-signals (intraday updates)
    • /v2/tm-grade (single-score context)
    • /v2/quantmetrics (risk/return framing)

    Why This Matters

    Precision beats guesswork. Hand-drawn lines are subjective and slow. The support and resistance API standardizes levels across assets and timeframes, enabling deterministic stops and take-profits your users (and bots) can trust.

    Production-ready by design. A simple REST shape, predictable latency, and clear semantics let you add levels to token pages, automate SL/TP alerts, and build rule-based execution with minimal glue code.

    Where to Find

    Need the Support and Resistance data? The cURL request for it is in the top right of the API Reference for quick access.

    👉 Keep momentum: Get API Key • Run Hello-TM • Clone a Template

    How It Works (Under the Hood)

    The Support/Resistance endpoint analyzes recent price structure to produce discrete levels above and below current price, along with strength indicators you can use for priority and styling. Query /v2/resistance-support?symbol=<ASSET>&timeframe=<HORIZON> to receive arrays of level objects and timestamps.

    Polling vs webhooks. For dashboards, short-TTL caching and batched fetches keep pages snappy. For bots and alerts, use queued jobs or webhooks (where applicable) to avoid noisy, bursty polling—especially around market opens and major events.

    Production Checklist

    • Rate limits: Respect plan caps; add client-side throttling.
    • Retries/backoff: Exponential backoff with jitter for 429/5xx; log failures.
    • Idempotency: Make alerting and order logic idempotent to prevent duplicates.
    • Caching: Memory/Redis/KV with short TTLs; pre-warm top symbols.
    • Batching: Fetch multiple assets per cycle; parallelize within rate limits.
    • Threshold logic: Add %-of-price buffers (e.g., alert at 0.3–0.5% from level).
    • Error catalog: Map common 4xx/5xx to actionable user guidance; keep request IDs.
    • Observability: Track p95/p99; measure alert precision (touch vs approach).
    • Security: Store API keys in a secrets manager; rotate regularly.

    Use Cases & Patterns

    • Bot Builder (Headless): Use nearest support for stop placement and nearest resistance for profit targets. Combine with /v2/trading-signals for entries/exits and size via Quantmetrics (volatility, drawdown).
    • Dashboard Builder (Product): Add a Levels widget to token pages; badge strength (e.g., High/Med/Low) and show last touch time. Color the price region (below support, between levels, above resistance) for instant context.
    • Screener Maker (Lightweight Tools): “Close to level” sort: highlight tokens within X% of a strong level. Toggle alerts for approach vs breakout events.
    • Risk Management: Create policy rules like “no new long if price is within 0.2% of strong resistance.” Export daily level snapshots for audit/compliance.

    Next Steps

    • Get API Key — generate a key and start free.
    • Run Hello-TM — verify your first successful call.
    • Clone a Template — deploy a levels panel or alerts bot today.
    • Watch the demo: Compare plans: Scale confidently with API plans.

    FAQs

    1) What does the Support & Resistance API return?

    A JSON payload with arrays of support and resistance levels for a symbol (and optional timeframe), each with a price and strength indicator, plus an update timestamp.

    2) How timely are the levels? What are the latency/SLOs?

    The endpoint targets predictable latency suitable for dashboards and alerts. Use short-TTL caching for UIs, and queued jobs or webhooks for alerting to smooth traffic.

    3) How do I trigger alerts or trades from levels?

    Common patterns: alert when price is within X% of a level, touches a level, or breaks beyond with confirmation. Always make downstream actions idempotent and respect rate limits.

    4) Can I combine levels with other endpoints?

    Yes—pair with /v2/trading-signals for timing, /v2/tm-grade for quality context, and /v2/quantmetrics for risk sizing. This yields a complete decide-plan-execute loop.

    5) Which timeframe should I use?

    Intraday bots prefer shorter horizons; swing/position dashboards use daily or higher-timeframe levels. Offer a timeframe toggle and cache results per setting.

    6) Do you provide SDKs or examples?

    Use the REST snippets above (JS/Python). The docs include quickstarts, Postman collections, and templates—start with Run Hello-TM.

    7) Pricing, limits, and enterprise SLAs?

    Begin free and scale as you grow. See API plans for rate limits and enterprise SLA options.

    Quantmetrics API: Measure Risk & Reward in One Call

    Token Metrics Team
    5

    Most traders see price—quants see probabilities. The Quantmetrics API turns raw performance into risk-adjusted stats like Sharpe, Sortino, volatility, drawdown, and CAGR so you can compare tokens objectively and build smarter bots and dashboards. In minutes, you’ll query /v2/quantmetrics, render a clear performance snapshot, and ship a feature that customers trust. Start by grabbing your key at Get API Key, 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 that fetches Quantmetrics for a token via /v2/quantmetrics (e.g., BTC, ETH, SOL).
    • A smoke-test curl you can paste into your terminal.
    • A UI pattern that displays Sharpe, Sortino, volatility, max drawdown, CAGR, and lookback window.

    Next Endpoints to Add

    • /v2/tm-grade (one-score signal)
    • /v2/trading-signals
    • /v2/hourly-trading-signals (timing)
    • /v2/resistance-support (risk placement)
    • /v2/price-prediction (scenario planning)

    Why This Matters

    Risk-adjusted truth beats hype. Price alone hides tail risk and whipsaws. Quantmetrics compresses edge, risk, and consistency into metrics that travel across assets and timeframes—so you can rank universes, size positions, and communicate performance like a professional.

    Built for dev speed

    A clean REST schema, predictable latency, and easy auth mean you can plug Sharpe/Sortino into bots, dashboards, and screeners without maintaining your own analytics pipeline. Pair with caching and batching to serve fast pages at scale.

    Where to Find

    The Quant Metrics cURL request is located in the top right of the API Reference, allowing you to easily integrate it with your application.

    Token Metrics provides real-time prices, trading signals, and on-chain insights all from one powerful API. Grab a Free API Key

    How It Works (Under the Hood)

    Quantmetrics computes risk-adjusted performance over a chosen lookback (e.g., 30d, 90d, 1y). You’ll receive a JSON snapshot with core statistics:

    • Sharpe ratio: excess return per unit of total volatility.
    • Sortino ratio: penalizes downside volatility more than upside.
    • Volatility: standard deviation of returns over the window.
    • Max drawdown: worst peak-to-trough decline.
    • CAGR / performance snapshot: geometric growth rate and best/worst periods.

    Call /v2/quantmetrics?symbol=<ASSET>&window=<LOOKBACK> to fetch the current snapshot. For dashboards spanning many tokens, batch symbols and apply short-TTL caching. If you generate alerts (e.g., “Sharpe crossed 1.5”), run a scheduled job and queue notifications to avoid bursty polling.

    Production Checklist

    • Rate limits: Understand your tier caps; add client-side throttling and queues.
    • Retries & backoff: Exponential backoff with jitter; treat 429/5xx as transient.
    • Idempotency: Prevent duplicate downstream actions on retried jobs.
    • Caching: Memory/Redis/KV with short TTLs; pre-warm popular symbols and windows.
    • Batching: Fetch multiple symbols per cycle; parallelize carefully within limits.
    • Error catalog: Map 4xx/5xx to clear remediation; log request IDs for tracing.
    • Observability: Track p95/p99 latency and error rates; alert on drift.
    • Security: Store API keys in secrets managers; rotate regularly.

    Use Cases & Patterns

    • Bot Builder (Headless): Gate entries by Sharpe ≥ threshold and drawdown ≤ limit, then trigger with /v2/trading-signals; size by inverse volatility.
    • Dashboard Builder (Product): Add a Quantmetrics panel to token pages; allow switching lookbacks (30d/90d/1y) and export CSV.
    • Screener Maker (Lightweight Tools): Top-N by Sortino with filters for volatility and sector; add alert toggles when thresholds cross.
    • Allocator/PM Tools: Blend CAGR, Sharpe, drawdown into a composite score to rank reallocations; show methodology for trust.
    • Research/Reporting: Weekly digest of tokens with Sharpe ↑, drawdown ↓, and volatility ↓.

    Next Steps

    • Get API Key — start free and generate a key in seconds.
    • Run Hello-TM — verify your first successful call.
    • Clone a Template — deploy a screener or dashboard today.
    • Watch the demo: VIDEO_URL_HERE
    • Compare plans: Scale with API plans.

    FAQs

    1) What does the Quantmetrics API return?

    A JSON snapshot of risk-adjusted metrics (e.g., Sharpe, Sortino, volatility, max drawdown, CAGR) for a symbol and lookback window—ideal for ranking, sizing, and dashboards.

    2) How fresh are the stats? What about latency/SLOs?

    Responses are engineered for predictable latency. For heavy UI usage, add short-TTL caching and batch requests; for alerts, use scheduled jobs or webhooks where available.

    3) Can I use Quantmetrics to size positions in a live bot?

    Yes—many quants size inversely to volatility or require Sharpe ≥ X to trade. Always backtest and paper-trade before going live; past results are illustrative, not guarantees.

    4) Which lookback window should I choose?

    Short windows (30–90d) adapt faster but are noisier; longer windows (6–12m) are steadier but slower to react. Offer users a toggle and cache each window.

    5) Do you provide SDKs or examples?

    REST is straightforward (JS/Python above). Docs include quickstarts, Postman collections, and templates—start with Run Hello-TM.

    6) Polling vs webhooks for quant alerts?

    Dashboards usually use cached polling. For threshold alerts (e.g., Sharpe crosses 1.0), run scheduled jobs and queue notifications to keep usage smooth and idempotent.

    7) Pricing, limits, and enterprise SLAs?

    Begin free and scale up. See API plans for rate limits and enterprise SLA options.
