How this service works
PRICE ATTESTATION: attest a live crypto or FX price (?asset=bitcoin&vs=usd) from a named source with timestamp — a data oracle. Returns JSON.
Output
A JSON object containing the attested current price of the requested asset (e.g. bitcoin) denominated in the specified quote currency (e.g. usd), along with the named data source and a precise timestamp of when the price was fetched — suitable for use as a verifiable price record or oracle data point.
Example use cases
Example prompt
“Can you get me an attested, timestamped price for bitcoin in USD right now — I need the source name and timestamp included so I can use it as a verified price record?”
Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/price-attestWhen to prefer
Choose this endpoint when you need a price with provenance — not just a raw number but an attested record that includes the source name and timestamp, useful for auditing, DeFi integrations, dispute resolution, or any context where you need to prove what the price was at a specific moment. Prefer it over generic price APIs when attestation and verifiability matter.
Side effects
- Unsupported asset symbol returns an error or empty result
- Unsupported vs currency returns an error
- Missing required query parameters (?asset= or ?vs=) returns a 400-style error
- Upstream price source unavailable causes a fetch failure
- Network timeout if the named source is slow to respond
