It is one of 69 paid API endpoints offered by DeFi Shield, a security intelligence platform designed for autonomous AI agents. The endpoint accepts POST requests and charges $0.75 per call, settled in USDC on Base via the x402 payment protocol.\n\nThe endpoint sits within the Protocol Intelligence category alongside related endpoints for TVL decomposition, protocol comparison, emission modeling, oracle risk, and bridge risk assessment. Based on the landing page description, it evaluates how centralized a protocol's governance structure is, producing a risk score. However, no detailed request/response schema, parameter documentation, or example payloads were found in the crawled material — the docs page returns 404.\n\nDeFi Shield supports endpoint discovery via GET requests to each endpoint path (returning free metadata including an `llm_usage_prompt`), a health endpoint at `/api/health` listing all endpoints and pricing, and an A2A discovery card at `/.well-known/agent-card.json`. Payment follows the x402 flow: the agent sends a POST with an x402 payment header, the facilitator verifies USDC payment on Base, the endpoint processes the request and returns JSON, and payment settles only on successful response.","tags":[],"capabilities":["governance-risk-scoring","protocol-intelligence","defi-analytics","x402-payment","usdc-base-settlement","ai-agent-api","centralization-analysis"],"categories":["defi","security","blockchain"],"synonyms":["governance centralization","protocol governance risk","DeFi governance scoring","DAO centralization risk","governance analysis API","protocol risk assessment","DeFi Shield governance"],"warnings":["No detailed API documentation available — /docs returns 404","No OpenAPI or JSON schema found for request/response payloads","x402 challenge body was empty — exact payment parameters (asset, amount, payTo) not captured","Example request JSON is inferred from naming conventions, not documented"],"endpointUrl":"https://defi-shield-hazel.vercel.app/api/protocol/governance-risk","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x0814d35F25F2EF3Dffa4aEF4d137558D5E51Ed7b","amount":"750000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live (returns 402 on POST as expected for x402), and the landing page provides pricing and a brief description.
