## 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-shorten-to-characters-6a2a3559 -d '<json body>'
```

Example prompt: Can you shorten this product description to 150 characters: 'Our handcrafted artisan coffee blends are sourced from the finest small-batch farms across Ethiopia, Colombia, and Guatemala, roasted fresh weekly to bring out complex, vibrant flavors'?

## When to prefer this

Choose this endpoint when you need a simple, reliable, pay-per-call text truncation operation without setting up your own string-processing logic. It is well-suited for agents that occasionally need to clip text to fit UI constraints, character limits, or storage schemas, and want a lightweight, stateless microservice rather than a full NLP pipeline.

## Known failure modes

- Missing or empty input text returns a validation error
- Character limit not provided or non-numeric causes a bad request
- Input object schema mismatch returns a 400 error
- Payment not included or insufficient results in a 402 Payment Required response
- Very large input strings may cause timeout or oversized payload errors
