Technical details
Endpoint
GEThttps://x402-crypto-apis.onrender.com/api/crypto/priceWhen to prefer
Use this endpoint when you need a single coin's real-time price, 24h change, and market cap in one lightweight call, especially in agent workflows that can handle micropayment via x402. Prefer over free-tier scrapers when reliability and freshness are required, and over heavier market-data APIs when you only need per-coin spot data rather than full order books or OHLCV history.
Side effects
- Invalid or unrecognized CoinGecko coin ID returns an error
- Payment not processed (x402 protocol failure) results in 402 response
- CoinGecko upstream outage causes stale or missing data
- Missing required 'coin' parameter returns a validation error
