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 signalharness-search-result-score-normalizer-32955879 -d '<json body>'
```

Example prompt: Take these raw search result scores from my query and normalize them to a consistent scale so I can compare them properly — here's the JSON: {"results":[{"id":"doc1","score":0.87},{"id":"doc2","score":143.2},{"id":"doc3","score":0.03}]}.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call microservice to normalize search result scores on the fly without spinning up custom normalization infrastructure. Particularly useful in agent pipelines that aggregate results from heterogeneous search backends with incompatible score ranges.

## Known failure modes

- Invalid or malformed JSON in request_json field — returns error
- Input JSON exceeds 65536 character limit — rejected
- Empty or too-short input string (minLength 2) — rejected
- Caller-supplied data fails internal schema validation — may return with warnings rather than hard failure

## Output

Returns a JSON object containing normalized score analysis, a warnings array (e.g. reminders to verify caller-supplied data), the original service_id, and a signed receipt with payment details, execution metadata, and a SHA-256 result hash for auditability.
