How this service works
Has this x402 endpoint been trustworthy over time? Track record of one endpoint from continuous independent monitoring: uptime %, the dated chronology of every payTo (receiver) change — the signal that catches hijacks — plus price-change history and trend. Compounding data that cannot be reconstructed after the fact: a snapshot tells you what an endpoint is, this tells you what it has been. ?endpoint=url
Output
Returns a structured record including: historical uptime percentage, a dated chronology of every payTo (payment receiver) address change (critical for detecting hijacks), and a history of price changes with trend data — all accumulated over continuous independent monitoring of the specified endpoint.
Example use cases
Vetting an unknown paid API before integrating
“Before I integrate this x402 endpoint at https://api.someservice.com/query into my app, can you check its full trust history — has the payTo receiver ever changed, what's its uptime been, and has the price moved around a lot?”
Detecting a potential endpoint hijack
“I'm worried this x402 endpoint might have been hijacked — can you pull the complete payTo change history for https://feeds.example.com/stream so I can see if the payment receiver was ever swapped out?”
Ongoing due diligence for agent payment decisions
“My agent is about to start paying https://data.thirdparty.dev/prices regularly — can you show me the historical trust record including uptime percentage and any past receiver or price changes so I can decide if it's safe?”
Technical details
Endpoint
POSThttps://pulsefeed.dev/trust/historyWhen to prefer
Use this endpoint when you need the longitudinal trust record of a specific x402 endpoint — especially the payTo change history — rather than just a current trust snapshot. It is the right choice when detecting past hijacks, performing due diligence before repeated payments, or auditing an endpoint's behavioral history over time. Prefer this over a current-status endpoint when historical continuity and tamper-evidence matter.
Side effects
- Unknown or unmonitored endpoint URL returns empty history or 404
- Malformed endpoint URL parameter returns an error
- Endpoint with no recorded history returns minimal data
- Network or service unavailability returns a timeout or 5xx error
