How this service works

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

Output

On successful payment: a JSON object containing the SKU name ('promptvault'), a descriptive title ('Prompt Vault'), the price ('$0.20'), and a diagnostic note confirming the paid shape. On unpaid requests: HTTP 402 with EIP-3009 payment challenge extras indicating the required payment amount and facilitator details.

Example use cases

Testing x402 payment gating integration

“Hit the Prompt Vault endpoint and confirm I get the paid JSON back with the promptvault SKU details — I want to make sure my x402 payment headers are being accepted correctly by OpenX402.”

Debugging a 402 payment challenge response

“Call the Prompt Vault API without a payment token and show me the full 402 response including the eip3009 extras, so I can see what my client needs to handle.”

Validating EIP-3009 authorization flow

“Use the Prompt Vault diagnostic to verify my EIP-3009 authorization signature is valid — send the request through OpenX402 and confirm I get the $0.20 USDC paid response back for the promptvault SKU.”

When to prefer

Choose this endpoint when you need a live, real-money x402 payment-gated API to test or demonstrate the x402 protocol with EIP-3009 authorization, specifically using the OpenX402 facilitator. It is ideal for developers building x402-compatible clients who need a reference endpoint that returns a well-defined paid JSON shape and a standard 402 challenge on unpaid requests.

Side effects

HTTP 402 returned when no valid x402 payment header is provided — includes eip3009 payment challenge extras
Payment rejected by OpenX402 facilitator if authorization signature is invalid or expired
Malformed properties parameter may result in an error response
Facilitator mismatch — only OpenX402 is accepted; other facilitators will not settle the payment
