How this service works
Is this x402 endpoint safe to pay? Vet an unknown seller BEFORE paying: pay/avoid verdict, 0-100 trust score, live 402 probe, scam flags (payTo hijack, bait-and-switch pricing, honeypot, wrong asset) and an on-chain check of the receiver on Base. Reads x402 v1 (body) AND v2 (PAYMENT-REQUIRED header) — body-only checkers call live v2 services dead. ?endpoint=url; omit for a trust-ranked catalog.
Output
Returns liveness status, validity check, reputation score, and uptime data for the queried x402 endpoint URL; when called without a parameter, returns a curated catalog of verified, working x402 services
Example use cases
Vet unknown x402 endpoint before paying
“I found this x402 API at https://datastream.io/api/prices that I want to use, but I've never paid for it before — can you run it through PulseFeed and tell me if it's live, trustworthy, and actually worth sending money to?”
Discover reliable x402 services catalog
“I'm looking to add some pay-per-call APIs to my agent workflow but I don't have specific endpoints in mind yet — can you pull up PulseFeed's catalog of verified, working x402 services so I can see what's out there?”
Confirm API uptime before agent deployment
“I'm about to deploy an agent that will repeatedly call the x402 service at https://analytics.xyz/v1/report — before I go live, can you check PulseFeed to confirm the endpoint has solid uptime and a good reputation score?”
Technical details
Endpoint
POSThttps://pulsefeed.dev/trustWhen to prefer
Use this endpoint when you need to vet an x402 pay-per-call service before committing funds — especially when you have no prior interaction history with that endpoint. Prefer this over generic uptime monitors because it is specifically designed for x402 micropayment services, understands their trust model, and provides reputation context relevant to whether a payment is safe to send. Also useful for discovering a curated list of reliably working x402 services when you don't have a specific endpoint in mind.
Side effects
- Queried endpoint URL is malformed or missing scheme — returns error or empty result
- Target x402 service is brand new with no reputation history — trust score may be unavailable or low confidence
- PulseFeed itself is temporarily unavailable — HTTP 5xx response
- URL parameter points to a non-x402 service — may return null or low-trust result
- Network timeout when probing the target endpoint — liveness check inconclusive
