Crypto price history

Historical price, market cap, and volume time series for a coin. Granularity is automatic per CoinGecko: <=1 day = 5-min bars, 2-90 days = hourly, >90 days = daily. Days: 1, 7, 14, 30, 90, 180, 365, or "max". Returns aligned arrays of {time, price, marketCap, volume}.

curl -i "https://agent402.tools/api/crypto-history?coin=BTC&days=7&currency=usd"

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/crypto-history?coin=BTC&days=7&currency=usd");

Wallet-only. This tool reaches the network/browser/storage, so it is paid in USDC via x402 (no proof-of-work tier).
