How this service works
What came back for a paid agent call, written down: every x402 endpoint and remote MCP server we watch, and every call we paid for.
Output
A JSON object confirming the delivery evidence record has been stored, containing details about the paid call response — including the endpoint called, the response payload received, and metadata identifying the transaction as a verified delivery record.
Example use cases
Audit trail for paid agent calls
“I just made a paid x402 API call and need to record exactly what the endpoint sent back so I have proof of delivery — can you write down the response as evidence?”
MCP server response verification
“After paying for a remote MCP server call, store the delivery record so I can verify later that the correct data was actually returned and I wasn't charged for nothing.”
x402 endpoint monitoring log
“I'm monitoring several x402 endpoints and just completed a paid call — log the response I received as an evidence record so I have an auditable history of what each endpoint delivered.”
Technical details
Endpoint
POSThttps://api.teppi.xyz/v1/web/evidence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a tamper-evident, machine-readable log of what an x402 paid API call actually returned — especially for auditing, dispute resolution, or proving delivery in automated agent pipelines where payment was made and you need evidence of the response received. It is purpose-built for the x402 micropayment ecosystem and MCP server monitoring context.
Side effects
- Missing or invalid call reference results in a rejection response
- Payment verification failure if the x402 transaction cannot be confirmed
- Duplicate submission of the same call evidence may return a conflict or deduplication response
- Malformed JSON body causes a 400-level error
- Endpoint or MCP server not found in the watched registry returns a not-found error
