# Verity Suite Distill

> Verity Suite Distill is a paid API for AI agents from suite.veritylayer.dev, paid per call via x402, $0.06/call, status unknown (last checked 2026-09-14).

Extracts structured, grounded facts from a text passage, returning only claims explicitly supported by the source text

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-17782be6 -d '<json body>'
```

Example prompt: Can you pull out the vendor name, invoice date, and total amount from this text: 'Invoice #1042 from Acme Corp, dated March 14 2025, for services rendered totaling $3,750.00. Payment due April 14 2025.'

## When to prefer this

Choose this endpoint when you need strictly grounded fact extraction — where hallucination or inference is unacceptable. It is ideal for financial, legal, or compliance contexts where every extracted value must map to an explicit span in the source. Prefer it over general LLM extraction when you need a machine-checkable fidelity signal and a fail-closed guarantee (it returns 'none' rather than guessing). It is best for short-to-medium passages up to 2000 characters where the fields of interest are likely to be explicitly stated.

## Known failure modes

- Text is empty, whitespace-only, or too short — status returns 'none' with empty facts array
- All requested fields are absent from the text — status is 'none', missing list contains all fields
- Text is garbled or truncated — status is 'none', service fails closed rather than hallucinating
- Only some requested fields are present — status is 'partial' with populated missing array
- Text exceeds 2000 character limit — request rejected at schema validation
- Input body missing required 'text' field — validation error returned

## How this service works

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

## Output

Returns a JSON object with a status ('extracted', 'partial', or 'none'), an array of 'key: value' fact strings copied or minimally normalized from explicit spans in the source text, a list of any requested field keys not grounded in the text, a fidelity score, and reasons explaining each grounding decision. Crucially, no values are inferred or fabricated — every fact maps to an explicit span.
