Pass ?at=<unix> for the historical price at a point in time. Sourced from DefiLlama across every major chain. Also accepts legacy ?ids=bitcoin,ethereum.

curl -si -X GET 'https://store.agentexchange.work/crypto/prices' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
