How this service works
Machine-readable settlement service
Output
A free-form JSON object representing the mock settlement response; schema is open (additionalProperties: true), so field names and values will vary depending on the mock configuration of the node.
Example use cases
Automated micropayment settlement testing
“I want to test a pay-per-call settlement flow against the PennyRail nano node — send a request with a generic input object and show me the mock settlement response it returns.”
x402 payment rail integration check
“Can you probe the PennyRail machine-readable settlement endpoint to confirm it accepts my input and returns a valid mock response? It charges $0.001 USDC per call via x402.”
Agent pipeline micropayment node call
“As part of my agent workflow, call the PennyRail nano settlement node with this input payload and relay back whatever the settlement response contains.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/openapi.mock-response--proven-openapi-mock-response?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to integrate or test an x402 micropayment-gated settlement node with minimal per-call cost ($0.001 USDC), especially in agent pipelines that require machine-readable pay-per-call settlement flows. It is best suited for automated agent workflows, mock API testing, and x402 protocol integration validation rather than production financial settlement.
Side effects
- Payment not authorized — x402 challenge not fulfilled, resulting in 402 Payment Required
- Malformed input — missing required 'input' field returns validation error
- Endpoint unavailable — Vercel deployment not active, returns 503 or timeout
- Empty or null input object — may return unexpected mock response or error
- Rate limiting — too many rapid calls may trigger throttling
