# 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 2026-09-13).

Validates submitted work proof objects (GPS bounds + artifact hash) and returns a deterministic completeness verdict on whether the proof meets required criteria.

## Facts

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 vealth-work-proof-check-bebc95db -d '<json body>'
```

Example prompt: Check if this work proof is complete — the work type is 'tree-planting' and the proof object includes GPS bounds for the site and an artifact hash of the uploaded photos.

## When to prefer this

Use this endpoint when you need a fast, deterministic, self-contained completeness check on a work proof before submission or further processing. Prefer this over manual review when you have structured proof objects with GPS bounds and artifact hashes and need a programmatic verdict. Not a substitute for third-party attestation services.

## Known failure modes

- Missing or malformed proof object returns validation error
- Unrecognized workType string may return incomplete verdict or error
- Missing GPS bounds or artifact hash in proof object causes incomplete verdict
- Payment of $0.01 USDC not settled results in 402 Payment Required
- Malformed JSON input returns 400 Bad Request

## How this service works

Work Proof Check (CDP-settled mirror) — deterministic completeness verdict on a submitted work proof (GPS bounds, artifact hash). A verification aid, not a third-party attestation.

## Output

A deterministic completeness verdict indicating whether the submitted work proof (GPS bounds and artifact hash) satisfies the required criteria for the given work type. The response is a validation aid, not a third-party attestation.
