Bounty Engineer Failure Cost Firewall
x402
Bounty Engineer Failure Cost Firewall is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $24.9/call, status unknown (last checked 2026-10-12).
Analyzes a caller-supplied dependency graph to compute blast radius, weighted exposure, and criticality scores, then decides whether to allow or block an operation based on failure-cost thresholds and node criticality limits.

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 allow/block decision, list of blockers (if any), affected nodes with their criticality and exposure, a list of critical nodes, gross and weighted exposure totals, affected count, a SHA256 report hash for audit purposes, and a limitations disclaimer clarifying the analysis is based only on the caller-supplied graph and does not execute or cancel any remote agent.
Example use cases
Pre-deployment blast radius check
“Before we deploy this agent update, check the failure cost firewall for my three nodes — payment-service (exposure $1200, criticality 1, depends on auth-service), auth-service (exposure $400, criticality 0.95, no deps), and logging (exposure $80, criticality 0.1, depends on auth-service) — targeting payment-service, with a max exposure of $2000 and max 2 critical nodes.”
Multi-agent spend risk gate
“I want to gate my agent pipeline before it calls any external APIs — run a failure cost check on nodes: orchestrator (exposure $500, criticality 1, depends on llm-router), llm-router (exposure $300, criticality 0.85, depends on cache), and cache (exposure $100, criticality 0.5, no deps), targeting llm-router, max exposure $900, and allow at most 2 critical nodes.”
Database dependency criticality audit
“Can you audit the blast radius if our database node fails? Graph nodes are: api-gateway (exposure $750, criticality 1, depends on db-primary), db-primary (exposure $300, criticality 0.95, no deps), and reporting (exposure $60, criticality 0.15, depends on db-primary) — target db-primary, cap exposure at $1500, max 3 critical nodes allowed.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/failure-cost-firewall?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, auditable risk gate before triggering multi-node agent workflows where financial exposure or cascading failures are a concern. It is best suited for autonomous agent pipelines that maintain an explicit dependency graph and want a deterministic allow/block decision with a verifiable SHA256 report, rather than a heuristic or manual risk review. Prefer this over generic monitoring tools when you need per-node criticality weighting and gross vs. weighted exposure decomposition in a single API call.
Side effects
- Invalid node array (fewer than 1 or more than 120 nodes) causes validation error
- target_ids referencing nodes not present in the nodes array may return unexpected results
- max_exposure_usd or max_critical_nodes set to zero or negative values may produce trivial block decisions
- Missing required fields returns schema validation error
- Service unavailability on onrender.com free-tier infrastructure may cause timeouts
- $24.9 USDC payment failure blocks the request before analysis begins
