Historical market chart for a coin by CoinGecko id: time-series of price, market cap, and volume over the last N days (1-365) in USD or another vs-currency. Granularity is auto-selected by range (hourly for short windows, daily for long). For backtests, charts, and trend analysis.
/api/crypto/coin-historyPAYMENT-SIGNATURE.The coin history API is a pay-per-call crypto endpoint built for AI agents and autonomous software. Historical market chart for a coin by CoinGecko id: time-series of price, market cap, and volume over the last N days (1-365) in USD or another vs-currency.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in coin history data source for an agent tool-use loop, an MCP host, or a backend that needs crypto data on demand without onboarding to yet another vendor portal.
