  title: CortexCloud On-Chain Data x402 Audit & Trust API
  description: 'Pay-per-call on-chain data and intelligence for AI agents: token, wallet, risk, whale, balance, NFT, transaction and cross-chain reads. Evidence-backed JSON, settled in USDC on Base via x402. No API keys, no signup.'
  version: 2.0.0
  x-guidance: 'CortexCloud — pay-per-call on-chain data for AI agents. Every paid route is POST/GET under /v1/data or /v1/aggregate and returns HTTP 402 with an x402 PaymentRequirements challenge (USDC on Base, eip155:8453) when no payment is attached. Sign the challenge (EIP-3009, gasless) and resend with the payment-signature header; the data comes back in the same response. GET /v1/capabilities lists every route and price for free. Discovery: /.well-known/x402.json, /.well-known/bazaar, /llms.txt, /openapi.json, and the MCP server at /mcp. No API keys, no subscriptions.'
