Technical details
Endpoint
GEThttps://workspace-x402-paywall.onrender.com/crypto/ohlcv?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call crypto price or OHLCV data without a subscription, especially when operating in an x402-compatible agent environment that can pay $0.005 USDC per query on Base or Solana mainnet. Ideal for low-frequency spot lookups where a full data subscription is overkill.
Side effects
- Invalid or unknown coin identifier returns an error or empty response
- Missing required 'coin' parameter causes a 400 bad request
- Payment failure (insufficient USDC balance or x402 handshake error) results in 402 Payment Required
- Requesting non-existent fields may return null or omit those fields silently
- Rate limiting or backend data provider downtime may cause 5xx errors
