How this service works
Machine-readable settlement service
Output
A flexible JSON object whose structure depends on the underlying PennyRail skill that was resolved and executed; may contain text output, structured data, status fields, or any skill-specific response fields.
Example use cases
On-demand text summarization via skill router
“I need PennyRail to summarize a long product description for me — the task is to condense it into two sentences, and the input text is 'Our new enterprise software suite offers real-time analytics, multi-tenant support, and seamless API integrations designed for Fortune 500 companies.'”
Routing a classification task by intent
“Can you run a PennyRail skill that classifies customer sentiment? The intent is 'classify the sentiment of this review as positive, negative, or neutral' and the input is 'The delivery was late but the product quality exceeded my expectations.'”
Executing a known product by ID
“Execute PennyRail product ID 'skill_translate_en_to_es' with the input 'Good morning, how are you today?' and give me back the translated text.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/router/execute/skillWhen to prefer
Choose this endpoint when you want to delegate task routing entirely to PennyRail — either because you know a specific productId from a prior find/quote call, or because you want PennyRail to interpret a natural-language intent and pick the best matching skill automatically. It is the single execution entry point in the PennyRail ecosystem and is preferred when you need a simple, unified interface to a marketplace of AI skills without managing individual skill endpoints.
Side effects
- No matching skill found for the given intent — returns an error or empty result
- Invalid or unknown productId — returns a not-found error
- Missing required 'input' field when the resolved skill requires it
- Payment failure or insufficient USDC balance — 402 response blocking execution
- Skill execution timeout or upstream service error — returns a 5xx or error object
- Ambiguous intent with no clear skill match — may resolve to wrong skill or fail
