Technical details
Endpoint
GEThttps://x402-paid-api.x402-finance.workers.dev/api/paid-content?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time cryptocurrency market data and are already using or open to the x402 micropayment protocol. It is ideal for agents that need fresh crypto prices on-demand without a subscription, paying only $0.002 USDC per call. Prefer this over subscription-based data feeds for low-frequency, pay-per-use access patterns.
Side effects
- Payment failure: insufficient USDC balance or wallet not configured for x402 payments — returns 402 Payment Required
- Invalid query parameters: unrecognized or malformed params return an error response
- Rate limiting or upstream data source unavailability causing 503 or timeout
- Network/Cloudflare Worker cold-start latency on first call
