Bounty Engineer Capability Fit Matrix
x402
Bounty Engineer Capability Fit Matrix is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-10-12).
Given a list of agent/API candidates and a set of required capability labels, returns a match matrix showing which candidates satisfy which requirements, their coverage ratio, and price.

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 per-candidate match results including: which requirements are matched, which are missing, price in USD, coverage ratio (0–1), and p95 latency if available. Also includes a top-level list of fully compatible candidates and the total requirement count. Note: matching is based on declared capability labels only and does not verify actual runtime capability.
Example use cases
Selecting cheapest fully-capable agent
“I have five candidate agents and I need all of them to support 'code-execution', 'json-output', and 'retry-logic'. Which ones fully cover all three requirements, and what's the cheapest option among the fully compatible ones?”
Gap analysis before multi-agent pipeline build
“Before I build my pipeline, can you check these four API candidates against my required capabilities — 'web-research', 'structured-output', and 'state-management' — and tell me exactly which capabilities each one is missing?”
Routing decision for autonomous spending agent
“I'm about to let an agent autonomously choose which sub-agent to call. Run a capability fit matrix on candidates 'agent-A' and 'agent-B' against the requirements 'spend-controls' and 'result-verification', and tell me their coverage ratios so I can set up the routing rule.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/capability-fit-matrix?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically select among multiple API or agent candidates based on a declared set of required capabilities, especially when cost and coverage ratio matter for routing decisions. Prefer this over manual comparison when you have more than two candidates or more than three requirements. It is not a runtime verifier — use it for pre-selection and routing logic, not for guaranteeing actual capability performance.
Side effects
- Candidates array is empty or exceeds 100 items — validation error
- Requirements array is empty or exceeds 60 items — validation error
- Candidate lacks declared capability labels — matched array will be empty, coverage_ratio will be 0
- Capability label mismatch due to non-normalized strings — requirements must match exact normalized labels
- Service unavailable on Render cold-start — may timeout on first request
