Real-time market data for trading bots
Crypto and stock feeds your trading bot can pay for per request in USDC. No account, no subscription, no API key.
- Pay per request with x402: a bot that trades once an hour pays for 24 calls, not a monthly plan.
- Buy a 30-day feed-scoped key in one 402 round-trip when volume grows.
- Quality probes every 5 minutes; feeds that go down return 503 and are never charged.

const pay = wrapFetchWithPayment(fetch, client); // @x402/fetch
const res = await pay("https://api.realtimeapi.ai/v1/cryptodata/market-health");
const data = await res.json(); // paid $0.01 in USDC on BaseFeeds for this use case
