How this service works
Machine-readable settlement service
Output
An open-schema JSON object returned after settlement processing; the exact fields vary (additionalProperties: true) but represent a machine-readable confirmation or resource payload tied to the submitted URL domain.
Example use cases
Automated domain resource micropayment
“Process 'mybrand.io' through the PennyRail settlement node so I can get a machine-readable response for that domain resource — handle the x402 payment automatically.”
Agent pipeline domain gating
“My agent needs to unlock the resource tied to 'api.acme.com' — submit that domain string to the PennyRail settlement service and return whatever the node sends back.”
Batch domain settlement testing
“Run 'testsite.dev' through the PennyRail nano settlement endpoint so I can verify the x402 payment flow returns a valid machine-readable payload.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/url.domain--url-domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically settle a micropayment (via the x402 protocol) tied to a URL domain string and receive a machine-readable response. It is suited for AI agent pipelines that need to unlock domain-gated resources for fractions of a cent in USDC. Prefer alternatives if you need human-readable output, bulk batch processing, or a domain lookup without a financial transaction component.
Side effects
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Invalid or malformed input string may return a 400 Bad Request
- Missing required 'input' field in request body causes schema validation error
- Network or Vercel hosting downtime results in 5xx errors
- Domain string not recognized by the settlement logic may return an empty or error payload
