## 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 signaldesk-ai-text-truncate-08127f70 -d '<json body>'
```

Example prompt: Truncate this product description to 150 characters and add '…' at the end if it gets cut: 'Our premium blend coffee is sourced from organic farms across Ethiopia, Colombia, and Guatemala, roasted fresh daily for maximum flavor.'

## When to prefer this

Choose this endpoint when you need a simple, reliable, Unicode-aware text truncation with optional suffix in a pay-per-call model without spinning up your own string-processing infrastructure. It is well-suited for agents that occasionally need to enforce display or storage length constraints without embedding custom logic.

## Known failure modes

- Input text exceeds the 4096 character input limit — request rejected
- Requested length exceeds the 4096 maximum — validation error
- Suffix longer than 20 characters — rejected
- Malformed JSON body — 400 error
- Payment not provided or insufficient — 402 Payment Required

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with a 'text' field containing the (possibly truncated) string and a 'truncated' boolean indicating whether any content was removed. If the input was already within the length limit, 'truncated' is false and 'text' equals the original input.
