## 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-text-truncate-fbfc78bf -d '<json body>'
```

Example prompt: Truncate this product description to 150 characters: 'Our handcrafted leather wallet is made from full-grain Italian leather, featuring 8 card slots, a hidden cash pocket, and RFID blocking technology for everyday carry.'

## When to prefer this

Use this endpoint when you need a simple, reliable, paid micro-service for text truncation without building custom string-handling logic. Particularly useful in agentic pipelines where text must be clipped to fit UI components, API field limits, or preview snippets, and you want a stateless, idempotent operation billed at $0.001 USDC per call via x402.

## Known failure modes

- Missing or malformed 'input' object returns a validation error
- No truncation parameters specified may result in no-op or error
- Payment failure or insufficient USDC balance causes 402 response
- Extremely large input strings may time out or be rejected
- Ambiguous truncation criteria (neither character nor word limit) may produce unexpected results
