+seoTitle: "Compounder Market API: Bounty Scoring for Autonomous Agents"
+seoDescription: "Evaluate a bounty or paid task with a deterministic score, expected value, and pursue-or-skip verdict. $0.01 USDC per call on Base via x402, no account or API key."
+agentSummary: "Compounder Market API lets an agent qualify a paid opportunity before committing hours to it. One POST returns a deterministic 0-100 score, pursue-or-skip verdict, expected value, weighted dimension breakdown, hard stops, risks, and a recommended action. Payment is $0.01 USDC on Base through x402 with no account or API key, and a free fixed sample shows the exact output structure first."

+classificationRationaleMd: "The listed product is machine-payable end to end: an autonomous caller discovers payment terms from the HTTP 402 response, pays per call from its own wallet on Base, and receives a structured decision payload. There is no account-based or human checkout path, and the service exists to serve autonomous operators qualifying paid work."
+inclusionRationaleMd: "The scorer provides a documented, specialized enrichment of an opportunity payload (weighted scoring, hard stops, and an expected-value verdict) in structured, agent-usable form, and it is callable as bounded machine work that materially improves opportunity triage beyond a generic API call."
+bestForMd: "Autonomous operators and agent builders that want a per-call, accountless way to triage a bounty, grant, or paid task on payout certainty, time-to-cash, and execution friction before committing work."
+notBestForMd: "Anyone looking for a bounty marketplace, escrow, or an opportunity feed: the API scores caller-supplied opportunities and does not source, hold, fund, or settle them."
+limitationsMd: "Scoring is decision support over caller-declared fields; results depend on the accuracy of the submitted data and are not an audit of the opportunity's real terms. Paid use requires a funded wallet with USDC on Base and an x402-capable client. The reviewed pages publish no independent accuracy benchmark."
+unknownsMd: "No independent benchmarks of scoring accuracy or service uptime were available at review time, and the operator publishes no usage metrics; verify the free sample and current behavior before relying on scores for consequential decisions."
+---
+Compounder Market API is a machine-payable decision service for autonomous operators. Its Bounty Fit Scorer takes a paid opportunity (a bounty, grant, or paid task) and returns a deterministic 0-100 score, pursue-or-skip verdict, expected value, weighted dimension breakdown, hard stops, risks, strengths, and a recommended next action.
+
+There is no account, API key, or subscription: a caller discovers the terms from the HTTP 402 response, settles $0.01 USDC per call on Base through x402 v2 (exact scheme), and settlement occurs only after a successful assessment. Discovery is free - the OpenAPI 3.1 contract, a machine integration guide, a compatibility manifest, a health endpoint, and a fixed sample generated by the same scorer are all public.
+
+## So agents can...
+- Qualify a bounty or paid task before committing hours of work to it
+- Act directly on structured output: score, expected value, hard stops, and a recommended action
+- Pay per call from a wallet on Base without an account, API key, or human checkout
+- Inspect the exact output structure for free, then integrate the paid route from the OpenAPI contract
