Endpoint
POSThttps://worlddata402.worlddata402.workers.dev/v1/crypto/market/%7Bid%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call, pay-as-you-go crypto market data without a subscription, especially in agentic or automated workflows that require infrequent or unpredictable lookups. Ideal for AI agents that need USDC-denominated micropayment-compatible data access on Base mainnet without managing API keys.
Side effects
- Unknown or invalid cryptocurrency ID returns a 404 or error response
- Payment failure or insufficient USDC balance blocks the request via x402 payment required
- Rate limiting or service unavailability may return 5xx errors
- Stale or delayed market data if upstream price feeds are lagging
