Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/token-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost per-call USD price for a named cryptocurrency token without needing an API key or account. Ideal for agents making ad-hoc price checks or enriching data pipelines with crypto prices on demand. Prefer this over subscription-based crypto data APIs when you only need occasional lookups and want to pay per call in USDC via x402.
Side effects
- Unknown or unsupported token symbol returns an error or empty response
- Misspelled token name may return no result or incorrect data
- Network or upstream data provider unavailability causes request failure
- Payment failure via x402 protocol prevents request from completing
- Token name ambiguity (e.g. multiple tokens with same ticker) may return unexpected result
