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 agentshelf-syntexa-ch-non-breaking-space-normalizer-7c68d610 -d '<json body>'
```

Example prompt: Can you normalize this text by replacing all non-breaking spaces with regular spaces: "Hello\u00A0World\u00A0this\u00A0has\u00A0nbsp\u00A0chars"?

## When to prefer this

Use this endpoint when you need a deterministic, zero-latency, no-LLM text normalization that specifically targets non-breaking space (U+00A0) replacement. Prefer the unpaid sandbox endpoint at POST /v1/sandbox/norm-nbsp-to-space for testing or when cost avoidance is important. Choose this over general-purpose LLM text cleaning when you need guaranteed behavior and exact cost predictability.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected
- Empty string input — rejected by minLength:1 constraint
- Missing 'text' field in request body — validation error
- Payment of exactly $0.005 USDC not provided — 402 Payment Required response

## How this service works

Call when an agent needs text normalized with nbsp-to-space. No network and no LLM. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/norm-nbsp-to-space first.

## Output

Returns the input text with all non-breaking space characters (U+00A0) replaced by regular ASCII space characters (U+0020), leaving all other characters unchanged.
