Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pennyrail-router-execute-network-c8d643ce -d '<json body>'
```

Example prompt: Use PennyRail to run this task — 'summarize the following text into three bullet points: [text]' — and route it to the best matching product on the network.

## When to prefer this

Choose this endpoint when you want to dynamically route a task to the best-matching PennyRail micro-service without knowing the exact product ahead of time, or when you have a specific PennyRail product ID and want to execute it directly with automatic USDC micro-payment settlement. Prefer it over manual API lookup when the task is expressed in natural language and the correct downstream service is uncertain.

## Known failure modes

- Intent cannot be matched to any PennyRail product — returns an error or empty resolution
- Product ID not found or deprecated — results in a resolution failure
- Input string malformed or rejected by the resolved product
- Payment authorization fails or USDC balance insufficient — transaction not settled
- Network or upstream micro-service timeout — partial or no result returned

## How this service works
