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 verity-suite-distill-quick-b15a5956 -d '<json body>'
```

Example prompt: Extract the patient name, date of visit, and diagnosis from this clinical note — and tell me how confident you are that each value is directly quoted from the text: 'Patient John Doe was seen on March 4, 2024. Presenting complaint: persistent cough. Assessment: acute bronchitis.'

## When to prefer this

Choose this endpoint when you need structured facts extracted from text with explicit grounding guarantees and calibrated confidence — especially when hallucination risk matters and you want a fidelity score proving each value was directly quoted. Prefer it over general LLM extraction when you need fail-closed behavior (status 'none' rather than a made-up answer), deterministic field targeting via the fields array, or an audit trail of reasons explaining what was and wasn't found.

## Known failure modes

- Text is empty, whitespace-only, truncated, or garbled — status returns 'none' with fidelity 0.0
- Requested fields are not present in the text — missing list populated, status is 'partial' or 'none'
- Text is too short to surface any grounded fact — status 'none', empty facts array
- Ambiguous spans cause fidelity score to drop below 0.7 with partial status
- Payment not included or insufficient — x402 payment-required response before processing

## How this service works

The trust fabric for AI agents — calibrated, fail-closed services agents pay per call.

## Output

Returns an array of 'key: value' fact strings copied verbatim or minimally normalized from explicit spans in the source text, an extraction status ('extracted', 'partial', or 'none'), a fidelity score from 0 to 1 indicating how directly each value is quoted, a list of any requested fields that were not grounded, and concrete reasons explaining the status and any gaps.
