## 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 agentshelf-collapse-space-text-normalizer-80700232 -d '<json body>'
```

Example prompt: Can you normalize this text by collapsing all the extra spaces and whitespace into single spaces: 'Hello   world,  this   is   a   test   string   with  lots  of   spaces.'?

## When to prefer this

Use this endpoint when you need a simple, deterministic, offline whitespace normalization with no LLM or network dependency, and you want a guaranteed fixed cost of $0.003 USDC per call. Prefer the free sandbox endpoint POST /v1/sandbox/norm-collapse-space when available to avoid charges.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Input exceeding 100,000 characters is rejected
- Payment not provided or insufficient USDC results in a 402 response
- Malformed JSON request body returns a 400 error

## How this service works

Call when an agent needs text normalized with collapse-space. No network and no LLM. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/norm-collapse-space first.

## Output

Returns the input text with all runs of whitespace (spaces, tabs, newlines) collapsed to a single space character, producing a clean, normalized string.
