How this service works
Machine-readable settlement service
Output
An open-ended JSON object containing the execution output from the resolved PennyRail product. The structure varies depending on which product was dispatched; the response is machine-readable and may include text, structured data, scores, or other task-specific fields.
Example use cases
Automated text processing via PennyRail
“I want to run a quick text task through PennyRail — take this sentence 'Climate change is the defining challenge of our era' and use the intent 'extract the main topic and sentiment' to get a machine-readable result back.”
Execute known PennyRail product by ID
“I have a PennyRail product ID 'prod_abc123' and I want to run it with the input 'What are the top 3 benefits of renewable energy?' — can you execute that product and give me the result?”
Dispatch agent sub-task to PennyRail router
“My agent needs to offload a classification step — send the intent 'classify this customer message as a complaint, question, or compliment' with the input 'I've been waiting three weeks for my order and no one has responded' to PennyRail and return whatever it resolves.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/router/execute/intelWhen to prefer
Choose this endpoint when you want to dynamically route a natural-language task to the appropriate PennyRail product without knowing the exact product ID upfront, or when you already have a PennyRail product ID and want to execute it directly. It is especially useful for AI agents that need to delegate micro-tasks to a settlement-backed execution layer with micropayment support via x402. Prefer this over manual product lookup when low-latency, one-shot task dispatch is needed.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted, resulting in a 402 error
- Invalid productId: if the specified productId does not exist or is inactive, the request may fail or route incorrectly
- Ambiguous intent: if the intent field is too vague, the router may resolve an unexpected product
- Missing required fields: omitting both intent and productId may result in a routing error
- Service unavailability: Vercel hosting may experience cold-start delays or downtime
- Malformed input: non-string or oversized input values may cause validation errors
