# Vealth Work Proof Check

> Vealth Work Proof Check is a paid API for AI agents from vealth.net, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Validates a submitted work proof against a job definition, returning a deterministic completeness verdict and listing any missing evidence artifacts.

## 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 vealth-work-proof-check-80450408 -d '<json body>'
```

Example prompt: Check whether my work proof for job definition 'job-def-abc123' is complete — I've submitted my proof object with the GPS coordinates and photo, and I want to know if anything is missing before I claim payment.

## When to prefer this

Use this endpoint when you need a deterministic, on-chain-anchored completeness verdict on a work proof before releasing payment or marking a task done. It is the authoritative check for Vealth job definitions and returns structured missing-artifact lists, making it ideal for automated agent workflows that need to confirm proof validity without manual review.

## Known failure modes

- Missing or malformed proof object returns validation error
- Invalid or unknown definitionId returns not-found error
- Proof submitted without required GPS or photo fields returns verdict 'incomplete' with missing list
- Location check fails if coordinates fall outside defined job boundary
- Network or payment failure (402) if USDC balance is insufficient

## How this service works

Find useful work. Build a life from it. Every job shows the place, the task, the proof, and the pay before you begin. Start today and grow toward mastery.

## Output

Returns a JSON object containing: a 'verdict' field (e.g. 'incomplete' or 'complete'), a 'missing' array listing absent evidence types (e.g. 'photo+GPS', 'signature'), a 'location_check' field indicating whether the worker was in bounds, and an 'artifact_sha256' hash of the submitted proof artifact.
