Extracts calibrated, verbatim-grounded structured facts from source text, returning fidelity scores and status for each extraction

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-pro-a7e99c14 -d '<json body>'
```

Example prompt: Pull out the name, date, and total amount from this invoice text and tell me how confident you are that each value is directly supported word-for-word: 'Invoice #4421 dated March 3 2025 — billed to Acme Corp, total due $4,750.00, net 30 terms.'

## When to prefer this

Choose this endpoint when you need verbatim-grounded fact extraction with explicit fidelity scoring and fail-closed behavior — i.e., you want the service to admit uncertainty rather than hallucinate values. Ideal for compliance, document parsing, or agent pipelines where downstream logic depends on knowing exactly which fields were and weren't found in the text.

## Known failure modes

- Text is empty, whitespace-only, or too short — returns status 'none' and fidelity 0.0
- Requested fields are not present in text — returns status 'partial' or 'none' with missing field list
- Text is garbled or truncated — returns status 'none'
- No fields requested and no salient facts found — returns empty facts array with status 'none'
- Ambiguous spans cause partial grounding — fidelity score lowered, status set to 'partial'
- Payment not provided or invalid — HTTP 402 returned 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 directly grounded in the source text, an overall fidelity score (0–1) indicating how verbatim each value is, a status of 'extracted', 'partial', or 'none' indicating coverage, a list of any requested fields not found, and reasons explaining the grounding and any gaps.
