  title: YO Risk Graph Public API
  version: '1.0'
  description: 'The YO Risk Graph (Exponential.fi Risk Ratings) exposed as HTTP APIs. Two surfaces: a free public Vault Exposure endpoint that returns a vault''s current collateral exposure, and a paid Agent API for full risk grading and dependency mapping across pools, assets, protocols and chains. The Agent API is monetized per-call via the x402 micropayment standard (v2) in USDC on Base mainnet (EIP-3009 transferWithAuthorization via Coinbase CDP; payer pays no gas). Paths and parameters are captured from the published docs; per-call prices are recorded as x-x402-price extensions.'
