# CoinStats

> Cryptocurrency portfolio tracker and crypto market data platform. Track portfolios across 300+ exchanges and wallets, monitor 20,000+ coins, plus DeFi positions, NFTs, and news — on web, iOS, Android, and Chrome.

CoinStats exposes its public market data three ways: a hosted MCP server for AI agents, an x402 pay-per-call gateway (no signup, USDC on Base), and a classic API-key REST API.

## For AI agents and automated clients

- [x402 Gateway](https://x402.coinstats.app): Pay-per-call HTTP-native API — USDC on Base, ~$0.001 per request. No signup. Endpoints self-describe via Coinbase Bazaar metadata in every 402 response.
  - `GET /coins`, `/coins/:coinId`, `/coins/charts`, `/markets`, `/news`, `/wallet/blockchains`, `/wallet/balance`
- [Hosted MCP Server](https://mcp.coinstats.app/mcp): Model Context Protocol endpoint with OAuth — paste the URL into Claude, Cursor, ChatGPT, or Codex to query your own CoinStats account.
- [MCP (local stdio)](https://www.npmjs.com/package/@coinstats/coinstats-mcp): `npx @coinstats/coinstats-mcp` with a developer API key.
