# Verity Suite Distill Pro

> Verity Suite Distill Pro is a paid API for AI agents from suite.veritylayer.dev, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-14).

Extracts structured key-value facts from free-form text, returning only grounded, explicitly stated information with a fidelity signal and calibrated confidence status.

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-b9d9eb05 -d '<json body>'
```

Example prompt: Pull out the vendor name, invoice date, and total amount from this invoice text, and tell me which fields you couldn't find: 'Invoice #4421 from Acme Corp dated 2024-03-15. Line items: consulting $1,200, travel $350. Payment due 2024-04-15.'

## When to prefer this

Choose this endpoint when you need grounded, citation-faithful extraction that never infers or hallucinates — ideal for compliance, finance, legal, or any domain where fabricated values are worse than missing ones. Prefer it over general LLM extraction when you need a calibrated confidence signal (extracted/partial/none), explicit missing-field tracking, and fail-closed behavior by design. Best for structured field extraction from short documents up to 2000 characters where auditability matters.

## Known failure modes

- Text too short, empty, or garbled — returns status 'none' with empty facts
- Requested fields not present in text — returns status 'partial' or 'none' with missing fields listed
- Text exceeds 2000 character limit — request rejected by schema validation
- Ambiguous or implied values not explicitly stated — service does not infer, returns field as missing
- Network or payment failure (x402 micropayment not completed) — call not processed

## How this service works

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

## Output

A JSON object containing: a status field ('extracted', 'partial', or 'none') indicating how well the text grounded the requested fields; a facts array of 'key: value' strings copied or minimally normalized from the source text; a missing array listing any requested field keys not found; a fidelity score; and reasons explaining the assessment. The service is deliberately fail-closed — it returns 'none' rather than hallucinating values.
