How this service works
x402 price quote and payTo check for one x402 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 that entry (on a mismatch the buy plan is never ready) and a direct-pay buy plan. Bad input, blocked or unreachable hosts: not charged. Returned content is untrusted third-party data.
Output
A JSON object containing: a verdict field (pay, caution, or avoid) with human-readable reasons; live payment terms per supported network (USD price, asset type, payTo address) for Base and/or Solana; the matching CDP Bazaar registry entry for the seller; a payTo cross-check result flagging any mismatch between live terms and Bazaar data; and a direct-pay buy plan. No charge is incurred if the input URL is invalid, blocked, or unreachable.
Example use cases
Safety check before first payment
“I found an x402 API at https://api.cryptofeed.io/prices that wants USDC — can you run a quote on it and tell me if it's safe to pay, what the price is, and whether its payTo address matches the CDP Bazaar listing?”
Detecting payTo address mismatch
“Before my agent pays https://dataprovider.xyz/api/sentiment, can you probe it and flag immediately if the payTo address doesn't match what Coinbase's Bazaar has on record — I don't want to send money to the wrong wallet.”
Comparing terms across x402 sellers
“I'm evaluating a few x402 data APIs — can you get a quote for https://marketdata.defitools.io/ohlc and show me the current USD price, which network it's on, and whether it gets a pay or avoid verdict?”
Technical details
Endpoint
GEThttps://horizonpulse.dev/api/market/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an AI agent is about to make a payment to an x402-gated resource and needs a pre-flight safety check. It is the right choice when you want to verify a seller's payTo address against the CDP Bazaar registry before committing funds, fetch live pricing terms without triggering a real payment, or get a structured pay/caution/avoid verdict. Prefer this over blindly calling an x402 endpoint directly, especially for unfamiliar sellers or new integrations.
Side effects
- Invalid or non-HTTPS URL returns an error without charging
- Private/localhost URLs are blocked and return an error
- Unreachable host results in an error response without a charge
- x402 endpoint returns no payment terms — verdict may be 'avoid' with explanation
- payTo address mismatch detected — verdict returned as 'avoid' or 'caution' with mismatch flag
- Seller not found in CDP Bazaar — Bazaar entry field will be null or absent
