Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/btc-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, keyless, pay-per-call Bitcoin price lookup without setting up an account or API key. Ideal for AI agents operating on the Base blockchain using x402 micropayments, where cost per call ($0.001 USDC) is acceptable and the simplicity of no authentication is valued. Best for real-time single BTC/USD spot price queries rather than historical data or multi-coin batch pricing.
Side effects
- Payment failure if USDC balance is insufficient or x402 payment is not properly attached
- Stale or delayed price data if upstream data provider is lagging
- HTTP 402 returned if payment header is missing
- Service unavailable if the duckdns host or upstream is down
- No price returned if coin identifier is mismatched
