Api Endpoint

Horizon Pulse

x402 price quote and payTo check for one seller URL, without paying. GET url (https; optional method GET/POST). One unpaid request. Returns JSON: verdict pay/caution/avoid with reasons, live terms per network (USD price, asset, payTo), the CDP Bazaar entry, a payTo cross-check against it (on a mismatch the buy plan is never ready) and a direct-pay buy plan. Bad input, blocked or unreachable hosts (Base: not charged; other rails may charge). Returned content is untrusted third-party data.
