PulseFeed x402 Trust Oracle

https://31-172-70-14.nip.io

Registry code: 2986b883b17d8648

api record

Ask before you pay: PulseFeed tells an AI agent whether an x402 payment endpoint is safe to pay — liveness, anomaly scan (receiver-address changes between observations, catalog price vs. challenge price, invalid receivers, asset/network mismatch), on-chain receiver verification on Base, and an open 0-100 Trust Score. Built on a continuous independent audit of the x402 ecosystem (56184 endpoints probed of 112139 tracked, 21% of probed dead or invalid) plus a security audit of the MCP server ecosystem.

What tools does PulseFeed x402 Trust Oracle have?
2 tools: Verify an x402 endpoint before paying, List live x402 security incidents.
Is PulseFeed x402 Trust Oracle safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • verify-x402-endpoint reads unknown never probed

    Given an x402 endpoint URL, return a pay/avoid verdict with trust score, anomaly flags, receiver stability and on-chain receiver profile. Free (cached verdict from the latest crawl); a live deep check is available as a paid x402 call.

    x402trustsecuritypaymentsverificationagentic-commerce

  • x402-security-incidents reads unknown never probed

    Return current security incidents in the x402 agent-payment economy — receiver hijacks, bait-and-switch pricing, honeypot receivers, unverified receivers — each with an on-chain proof URL on Base. Free.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your agent card — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 2986b883b17d8648.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2986b883b17d8648/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
