x402
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.

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).
Example use cases
Bounty payout gate for agent task
“Before releasing the bounty payment, verify that the agent's deliverable has at least 10 items in the results array and that the status field equals 'complete'.”
Contract condition check before state transition
“I have a workflow that only advances when the deliverable passes two rules: the score field must be greater than 0.8 and the errors array must have length zero. Can you run the acceptance gate on this output?”
Automated QA on structured API response
“Run an acceptance check on this API response — I need to confirm the currency equals 'EUR' and the data array has at least 1 entry before I log it as successful.”

Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/task-acceptance-gate?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
