How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

Output

Returns a JSON object containing the SKU ('escrowslip'), a descriptive note indicating this is a paid diagnostic shape, the price ('$0.20'), and a title ('Escrow Slip'). If payment via x402/EIP-3009 is not included or fails, returns HTTP 402 with EIP-3009 payment requirement extras instead.

Example use cases

Verify x402 payment channel works

“Check if my x402 micropayment setup is correctly configured by retrieving the escrow slip diagnostic — I need to confirm the EIP-3009 payment goes through and I get back the paid JSON response, not a 402 error.”

Debug unpaid 402 response

“I'm getting HTTP 402 errors back from my x402 integration — can you hit the escrow slip endpoint to see what the EIP-3009 extras look like so I can figure out what payment fields I'm missing?”

Confirm OpenX402 facilitator connection

“Test my connection to the OpenX402 facilitator by pulling the escrow slip diagnostic — I want to make sure the $0.20 USDC payment is being processed and the SKU comes back as 'escrowslip' in the response.”

When to prefer

Choose this endpoint when you need to test, debug, or validate an x402 HTTP micropayment integration specifically using the OpenX402 facilitator and EIP-3009 payment authorization. It is purpose-built as a diagnostic tool — not a production data API — making it ideal for confirming that your agent's crypto payment plumbing works before connecting to real paid endpoints. Prefer this over generic HTTP testing tools when the goal is specifically to verify x402 payment flow end-to-end.

Side effects

HTTP 402 returned when no valid x402 payment header is present — includes EIP-3009 extras describing how to pay
Payment rejected if facilitator is not OpenX402 — only OpenX402 is supported as facilitator
Malformed or missing properties parameter may result in error response
USDC amount mismatch (not exactly $0.20) may trigger payment failure
EIP-3009 authorization expired or invalid signature causes 402
