CoinKirin is a cryptocurrency data platform providing real-time prices, market capitalizations, trading volumes, rankings, news, and related tools for tens of thousands of digital assets. Our mission is to make cryptocurrency market data accessible and understandable for everyone.
We believe everyone should have free access to transparent, accurate cryptocurrency market data. Our mission is to empower investors, researchers, and developers worldwide with real-time data, powerful tools, and comprehensive analytics — available in 100 languages and accessible to both humans and AI.
Our market data is aggregated from multiple sources including blockchain networks, official project websites, cryptocurrency exchanges, and publicly available internet data. Prices, market caps, trading volumes, and other metrics are updated in real time to ensure accuracy and reliability.
CoinKirin provides a fully public REST API with CORS enabled for all origins, so your applications and AI agents can query live data with no barriers. Browse the interactive OpenAPI docs to discover all 80+ endpoints, or visit the Developer Hub for guides, code examples, and API key plans. We also ship an MCP server so LLM-based agents (Claude, GPT, etc.) can directly query coin prices, rankings, and market stats without scraping HTML. A free tier is available; premium plans unlock higher rate limits and historical data.
