Add Compounder Market API

[SupremeDreamZ]

Tool

Compounder Market API — a machine-payable bounty scoring API for autonomous operators. One paid POST returns a deterministic 0–100 score, pursue-or-skip verdict, expected value, weighted dimension breakdown, hard stops, risks, and a recommended action, settled at $0.01 USDC per call on Base through x402 v2.

• Category: specialized-search-discovery-engines
• Classification: agent-native
• Pricing: paid ($0.01 USDC per call; no account, API key, or subscription)
• Website: https://compounder-market-api.vercel.app

Inclusion test

1. Classification — agent-native: the paid surface is machine-native end to end. The 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.
2. Concrete agent outcome: an agent can qualify a bounty, grant, or paid task — payment certainty, time-to-cash, execution friction, expected value — before committing hours of work to it, and act directly on the structured output.
3. First-party evidence: the homepage, the machine integration guide (llms.txt), the OpenAPI 3.1 contract, and a free fixed sample generated by the same deterministic scorer; each is cited in evidenceSources with access date 2026-10-02.
4. Substance: an original deterministic scoring core (documented weighted model with hard stops and penalties) with published request/response schemas and min/max limits — not a wrapper, integration badge, or generic compatibility layer.
5. Defensibility: every material claim maps to a first-party source, and limitations/unknowns (decision-support bounds, newness, no independent benchmark) are stated on the listing.
