## 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 bounty-engineer-proof-work-audit-a095fb6b -d '<json body>'
```

Example prompt: Audit this HTML artifact against our bounty policy and tell me whether it passes the structural checks and whether a payout is guaranteed — submit it in HTML format.

## When to prefer this

Use this endpoint when an autonomous agent or developer needs to programmatically verify that a bounty artifact (SVG, HTML, or JSON) meets structural requirements before claiming or releasing a payout. It is specifically suited for bounty-gated workflows where proof-of-work validation is required prior to award confirmation, and where the x402 micropayment model is acceptable at $0.05 per audit call.

## Known failure modes

- Artifact exceeds 180,000 character limit — submission rejected
- Invalid format enum value (not svg, html, or json) — validation error
- Malformed or missing policy object — audit cannot run
- Artifact fails structural checks — decision field returns failure reason
- Payment of 0.05 USDC not completed — x402 payment required error
- Service unavailable on Render hosting — 502 or timeout

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object with: 'ok' (boolean success flag), 'mode' set to 'proofwork_audit_v1', 'decision' string indicating the audit outcome (e.g. 'structural_checks_passed'), and 'award_or_payout_guaranteed' boolean indicating whether the artifact qualifies for a guaranteed bounty payout.
