Bounty Engineer Agent Execution Gate
x402
Bounty Engineer Agent Execution 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 2026-10-10).
Acts as a gating layer for autonomous agent tool calls, enforcing spend controls, idempotency, retry planning, and decision routing before an agent action executes.

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 'ok' boolean, the execution mode ('agent_execution_gate'), a tool decision object containing 'allow' or 'deny', a top-level 'decision' field, and an idempotency object indicating whether the action slot was 'reserved' or already consumed.
Example use cases
Spend-controlled agent tool authorization
“My agent is about to call an external API that costs money — run it through the execution gate with action ID 'enrich-lead-07', namespace 'sales-agent', fingerprint 'xyz789', and a 90-second TTL to make sure we're within budget and it hasn't already been tried.”
Idempotency check before retry
“My agent pipeline failed halfway through and I need to retry action 'parse-github-issue-12' — gate it with fingerprint 'retry-fg-55', namespace 'bounty-dev', TTL 30 seconds, and confirm whether this execution is safe to proceed or was already reserved.”
Margin-aware routing for agent API calls
“Before my agent fires off a funded-rate data fetch, run it through the execution gate — action ID 'funding-rate-fetch-btc', namespace 'trading-bot', fingerprint 'fr-gate-001', TTL 45 seconds — and confirm the decision so I know whether to allow or block the spend.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/agent-execution-gate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs a centralized gate to authorize, deduplicate, and spend-control individual tool calls before execution — especially in multi-step pipelines where idempotency, retry safety, and budget enforcement are critical. Prefer this over ad-hoc agent logic when you need a single decision point that combines fingerprinting, TTL-based reservation, and namespace-scoped spend controls in one call.
Side effects
- Action already executed (idempotency conflict) — returns decision 'deny' with idempotency status 'conflict'
- TTL too short (below 30 seconds minimum) — request rejected with validation error
- Missing required fields (tool, action_id, fingerprint) — 400-level error
- Insufficient funds or spend limit exceeded — decision 'deny' with spend control reason
- Service unavailable on Render cold start — timeout or 503 error
- Invalid namespace_key — unauthorized or unrecognized namespace response
