POSThttps://worlddata402.worlddata402.workers.dev/v1/crypto/%7Bids%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call cryptocurrency market data without a subscription, especially in agentic workflows that use x402 micropayments on Base mainnet (USDC). Ideal when you want to avoid API key management and pay only for what you query.

- Payment failure over x402 if USDC balance is insufficient
- Rate limiting or rejection if micropayment is not processed correctly
- Network timeout from Cloudflare Workers edge node
