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 signaldesk-ai-whitespace-normalizer-5a116cee -d '<json body>'
```

Example prompt: Can you clean up this text for me — it has a bunch of extra spaces and weird spacing between words: 'Hello   world,  this   is   a   test.'

## When to prefer this

Choose this endpoint when you need a simple, fast, paid-per-call whitespace normalization step in an agent pipeline, particularly when using x402-compatible micropayment infrastructure. Suited for preprocessing pipelines where consistent spacing is required before downstream NLP or display tasks, and where a managed API call is preferred over running custom string logic.

## Known failure modes

- Text exceeds 4096 character limit — request rejected
- Empty or missing 'text' field — validation error returned
- Payment of 0.001 USDC not fulfilled — 402 Payment Required response
- Malformed JSON body — parse error returned

## 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

A JSON object with a 'text' field containing the input string with all whitespace sequences collapsed into single spaces, resulting in a clean, uniformly spaced string.
