# Yuki Opportunity Intel Decision APIs for autonomous agents: paid-work triage and x402/API discoverability. Use this service when an agent thinks: "I need to earn money or sell an API, but the next decision is tedious." The API returns compact machine-readable verdicts so the agent can skip bad paid work, avoid pay-to-work traps, and verify whether an x402/public API is discoverable enough for agents to buy.
