Jentic publishes the only available OpenAPI specification for CoinMarketCap API, keeping it validated and agent-ready. CoinMarketCap is the most widely cited cryptocurrency rankings and market cap source — the Pro API exposes 23 endpoints covering listings, quotes (latest and historical), OHLCV candles, market pairs, exchange data, global metrics, trending coins, categories, fiat mappings, and a price conversion tool. Trading platforms, news sites, and analytics tools rely on it for benchmark pricing.

Use Cases

Patterns agents use CoinMarketCap API API for, with concrete tasks.

★ Authoritative Rankings and Market Cap Display

Render the canonical ranked list of cryptocurrencies by market cap that users recognise from coinmarketcap.com. The /v1/cryptocurrency/listings/latest endpoint returns paginated coins with rank, price, market cap, and 24-hour change. Useful for explorers, exchanges, and market overview pages.

Call GET /v1/cryptocurrency/listings/latest with limit=100 and convert=USD and return the ranked list

OHLCV-Based Charting

Render OHLCV candles for a coin over chosen intervals using the v2 OHLCV endpoints. Supply latest or historical date ranges to power line and candlestick charts in trading dashboards or research tools.

Call GET /v2/cryptocurrency/ohlcv/historical with id, time_start, time_end, and interval=daily and return the candle series

Trending and Discovery Feeds

Power discovery surfaces (newsletter highlights, homepage carousels, alert feeds) using the trending and gainers-losers endpoints. They return short ranked lists CoinMarketCap publishes itself, so the data matches what readers see on the site.

Call GET /v1/cryptocurrency/trending/gainers-losers with time_period=24h and return the top five gainers

AI Market Briefing Agent via Jentic

Build an agent that produces a daily crypto market briefing using CoinMarketCap data through Jentic. The agent expresses an intent (give me a market briefing); Jentic resolves the right combination of listings, global metrics, and trending endpoints, then executes them with stored credentials. Cost-aware for assistants needing authoritative pricing without managing the X-CMC_PRO_API_KEY secret in agent context.

Through Jentic, fetch global metrics, top 10 listings, and top 5 gainers in 24h, then return a brief market summary

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

CoinMarketCap Pro API keys are stored encrypted in the Jentic vault. Agents receive scoped execution tokens — the X-CMC_PRO_API_KEY header is set server-side at execution and never enters the agent's prompt or logs.

Intent-based discovery

Agents search Jentic by intent (e.g. get top crypto by market cap) and Jentic returns the matching CoinMarketCap operation with its parameter schema, so the agent calls the correct endpoint without browsing docs.

Time to first call

Direct integration: 1-2 days for auth, credit-aware backoff, and pagination across paid endpoints. Through Jentic: under 1 hour — search, load schema, execute.

FAQs

Specific to using CoinMarketCap API API through Jentic.

Why is there no official OpenAPI spec for CoinMarketCap API?

CoinMarketCap publishes interactive Pro API documentation but does not distribute a machine-readable OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call CoinMarketCap API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the CoinMarketCap API use?

The Pro API requires an API key sent in the X-CMC_PRO_API_KEY header. Through Jentic, the key is stored in the encrypted vault and the agent receives a scoped execution token rather than the raw key string.

Can I retrieve historical OHLCV candles with the CoinMarketCap API?

Yes. GET /v2/cryptocurrency/ohlcv/historical accepts an id or symbol along with time_start, time_end, and interval (e.g. daily, weekly), returning OHLCV records suitable for charting and backtesting.

What are the rate limits for the CoinMarketCap API?

CoinMarketCap charges in monthly call credits and per-minute throughput that depend on the plan tier (Basic, Hobbyist, Startup, Standard, Professional, Enterprise). The OpenAPI spec does not declare exact thresholds; check your plan and call /v1/key/info to see the current usage.

How do I convert an amount between two currencies through Jentic?

Install the SDK with pip install jentic, search Jentic for convert cryptocurrency amount, load the schema for GET /v1/tools/price-conversion, and execute with amount, symbol, and convert parameters.

Does the API expose CoinMarketCap categories and tags?

Yes. GET /v1/cryptocurrency/categories returns all category groupings, and GET /v1/cryptocurrency/category returns the coins inside a specific category — useful for thematic dashboards (DeFi, gaming, layer-1 etc.).
