Crypto price history over a window (CoinGecko free). Returns daily price series (open/close per day), market cap, volume. Use ?id=bitcoin and vs=usd and days=30 (max 365 on free tier). Built for AI agents doing TA and back-testing. Accepts payment on Base or Solana — either network works.
Warnings
Unusual seller traffic This seller's paid usage looks manufactured: paid calls to trivial endpoints like ping or uuid, or near-identical payer counts on every endpoint. Its usage counts half.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
