## 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-normalizer-6c9a1e6b -d '<json body>'
```

Example prompt: I have a raw JSON search result from an external API and I need it normalized into a consistent, schema-valid format — can you run it through the SignalHarness search result normalizer and give me the cleaned output?

## When to prefer this

Choose this endpoint when you need to normalize or standardize search result JSON from heterogeneous sources into a consistent schema, especially in agentic pipelines that aggregate results from multiple search APIs. It is well-suited for pre-ingestion validation and normalization steps where consistency is critical. At $0.005 USDC per call it is cost-effective for high-frequency normalization tasks.

## Known failure modes

- Invalid or malformed request_json input may cause parsing errors
- JSON exceeding 65536 characters will be rejected
- Caller-supplied data that cannot be normalized may produce warnings but still succeed
- Payment failure on Base network may prevent execution
- Empty or too-short JSON strings (below 2 characters) will be rejected

## Output

Returns a normalized analysis_json containing the standardized search result data, along with any warnings (e.g. about caller-supplied data), a service_id, evidence_scope, status, and a full execution receipt including payment details, result SHA-256 hash, network info, and timing metadata.
