Technical details
Endpoint
POSThttps://bb-crypto.vercel.app/api/coingeckoWhen to prefer
Choose this endpoint when you need CoinGecko market data but want a micropayment-gated proxy that integrates with x402 payment flows on Base, avoiding direct CoinGecko API key management. Useful for agents operating within x402-enabled payment infrastructure.
Side effects
- Payment not accepted — 402 returned if USDC micropayment not included or insufficient
- Invalid coin ID or symbol returns empty or error response
- CoinGecko API rate limit or downtime causes upstream failure
- Malformed POST body results in 400 bad request
- Unsupported currency denomination returns no price data
