It lists coins and returns a coin's price, markets, OHLC candles, and price chart, along with exchange and DEX listings, categories, and chains. Market-wide signals include trending and newly listed coins, the Fear and Greed index and its history, ETF flows, liquidations, global market status, and crypto news. Every request uses an API key, calls are free within a per-key hourly quota, and a Data by Coinmico attribution is required. ## For AI agents Read cryptocurrency prices, OHLC candles, markets, exchanges, DEXs, trending and new coins, the Fear and Greed index, ETF flows, liquidations, and news over a read-only REST API. ## Scope Does not execute trades, hold funds, or manage wallets. Use for reading cryptocurrency market data only. ## Capabilities - List coins and read a coin's price, markets, and OHLC candles - Fetch spot prices and price charts for coins - Read exchange and DEX listings and their details - Track market sentiment with the Fear and Greed index and its history - Follow trending and newly listed coins - Read ETF flows, liquidations, and overall market status - Search coins and browse categories and chains ## Use cases ### Agent-Read Crypto Data Through Jentic An AI agent that reasons over crypto markets can read Coinmico through Jentic instead of integrating the API by hand. The agent pulls a coin's price and OHLC candles, checks the Fear and Greed index, and reads trending coins to inform a response. Because the API is read-only, the agent cannot move funds or place trades no matter what it calls. Example prompt: Get the current price and the last day of OHLC candles for a coin and summarize its recent movement ### Market Monitoring and Price Tracking A monitoring workflow can poll Coinmico for prices, charts, and markets to track assets over time. It lists the markets a coin trades on, reads its price chart, and watches global market status so a dashboard or alert stays current. Example prompt: Fetch the price and markets for a coin and compare its current price against yesterday's close from the chart ### Sentiment and Trend Analysis Coinmico surfaces market sentiment and momentum signals an analyst can read programmatically. The Fear and Greed index and its history show sentiment over time, while trending and newly listed coins reveal where attention is flowing. Example prompt: Read today's Fear and Greed index and the current trending coins to assemble a market sentiment snapshot ### Derivatives and ETF Flow Tracking For a view beyond spot prices, Coinmico reports ETF flows per asset and across all assets, liquidation activity, and overall market status. A workflow can read ETF inflows and outflows alongside liquidations to gauge positioning. Example prompt: Read the latest ETF flows for an asset and the recent liquidations to report net positioning ## Key endpoints | Method | Path | Description | | --- | --- | --- | | GET | `/v1/coins` | List coins | | GET | `/v1/coins/{id}` | Get a coin | | GET | `/v1/coins/{id}/ohlc` | Get OHLC candles | | GET | `/v1/prices` | Get prices | | GET | `/v1/exchanges` | List exchanges | | GET | `/v1/trending` | Get trending coins | | GET | `/v1/fear-greed` | Get the Fear and Greed index | | GET | `/v1/etf-flows` | Get ETF flows for all assets | ## Key resources - **Coins and Prices** — Coin listings and detail, spot prices, OHLC candles, price charts, and a coin's markets - **Exchanges and DEXs** — Centralized exchange and decentralized exchange listings and their details - **Market Signals** — Trending coins, new coins, Fear and Greed index and history, and price discovery - **Derivatives and Macro** — ETF flows per asset and across all assets, liquidations, global stats, and market status - **Reference and News** — Coin search, categories, chains, and crypto news ## AI readiness This API is usable in Jentic One now. Its AI-readiness score against Jentic's framework shows where it stands today and where improvements would make it even easier for agents to use. - **Score:** 53 / 100 - **Maturity:** Foundational - **Dimensions:** - Foundational Compliance: 71 / 100 - Developer Experience & Jentic Compatibility: 59 / 100 - AI-Readiness & Agent Experience: 31 / 100 - Agent Usability: 94 / 100 - Security: 55 / 100 - AI Discoverability: 63 / 100 - **View full report:** https://jentic.com/apis/coinmico.com/coinmico/scorecard - **How the score is calculated:** https://docs.jentic.com/reference/api-readiness-framework/overview/ - **More about the dimensions:** https://docs.jentic.com/reference/api-readiness-framework/specification/#dimensional-model-overview ### Score it yourself Every API in the directory is allowlisted, so you can re-score it with no key required. - **Score your own API:** https://jentic.com/scorecard.md - **Scoring CLI agent skill:** https://github.com/jentic/jentic-api-scorecard/blob/main/skills/jentic-api-scorecard/SKILL.md ```sh npx @jentic/api-scorecard-cli score ``` ## Why Jentic - **Setup:** Wiring the Coinmico API by hand means getting a key from its dashboard, sending it as an x-api-key header or a bearer token, and adding the required Data by Coinmico attribution. Through Jentic you install once, import Coinmico from the API Directory, store the key once, and your agent calls it. - **Permission scoping:** The Coinmico API is read-only, and each coin or exchange id travels in the URL path, so a rule can bound your agent to the read operations it needs, such as prices and coins. Because every operation only reads market data, nothing it can call changes state. - **Credential handling:** Your Coinmico key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context. - **Discovery method:** Agents search Jentic by intent such as get a coin's price or check the Fear and Greed index, and Jentic returns the matching Coinmico operation with its input schema so the agent calls the right endpoint without reading the reference docs. ## Related APIs - **CoinGecko** — A widely used crypto market data API covering coins, prices, and exchanges. - **CoinMarketCap** — Crypto prices, market caps, and rankings from a large market-data provider. - **Binance** — An exchange API that executes trades, which Coinmico's read-only data does not. ## FAQ ### What authentication does the Coinmico API use? The Coinmico API authenticates with an API key, sent either in the x-api-key header or as a bearer token, per its OpenAPI spec; you get the key from the Coinmico dashboard. Through Jentic the key is stored encrypted by your own Jentic One instance and injected at call time, so it never reaches the agent's context. ### What market data can I read from the Coinmico API? You can read coin prices, OHLC candles, and price charts, list exchanges and DEXs, follow trending and newly listed coins, and check the Fear and Greed index. It also exposes ETF flows, liquidations, categories, chains, overall market status, and crypto news. ### What are the rate limits for the Coinmico API? The API allows 600 requests per hour per key, per its own documentation, and it is read-only and free. If you need more throughput, check the vendor documentation at https://coinmico.com for current plans. ### How do I get a coin's price with the Coinmico API through Jentic? Install Jentic One, then import Coinmico from the API Directory and store your key once. Your agent searches by intent such as get a coin's price, and Jentic returns the prices operation with its input schema so the agent reads the current price back. Remember to include the Data by Coinmico attribution the API requires. To run it on your own infrastructure, install Jentic One from its GitHub repo. ### Is there a Coinmico API MCP server? You don't need an MCP server to give your agent the Coinmico API. Jentic connects it directly from the API Directory: import it, store your key once, and your agent calls the price, market, and sentiment operations on demand. Operations are discovered when the agent needs them, so they do not fill its context ahead of time. ### Can I limit what my agent is allowed to do with the Coinmico API? Yes. The API is read-only, so a rule that allows only the data operations your agent needs, such as prices and coins, lets it read market data and reach nothing else. Nothing it can call changes state, and every call it makes is logged.
