# Bounty Engineer Task Acceptance Gate

> Bounty Engineer Task Acceptance Gate is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Evaluates a task deliverable against a set of deterministic acceptance rules and returns a pass/fail decision with per-rule results and a content hash.

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 bounty-engineer-task-acceptance-gate-b0d68663 -d '<json body>'
```

Example prompt: Check if this deliverable passes my acceptance rules: it should have an items array with at least 3 entries and a currency field equal to 'USD' — here's the JSON output from the previous step.

## When to prefer this

Use this endpoint when an autonomous agent needs a deterministic, auditable pass/fail verdict on a structured deliverable before triggering payment, state transitions, or bounty release. It is ideal for agentic workflows requiring tamper-evident receipts (SHA-256 hash) and explicit rule-by-rule traceability. Prefer it over custom validation logic when you need a standardized acceptance contract that can be logged and disputed later.

## Known failure modes

- Missing or empty acceptance_rules array causes a 400-level error
- Deliverable field not provided or malformed JSON results in validation failure
- Rule paths that do not exist in the deliverable are flagged as not found and fail
- Operators not supported by the engine may return errors or unexpected results
- Network timeout or service unavailability on Render cold-start returns 5xx

## 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 an overall accept/reject decision, a per-rule breakdown showing each rule's id, path, operator, found status, and pass/fail result, a SHA-256 hash of the deliverable for audit purposes, counts of passed and failed rules, and a list of evaluation limitations (e.g. no subjective or legal judgment).
