  title: HostDeFi Token Risk Keys API
  version: 1.0.0
  description: 'Public product surface of the scam-check-api service: the /v1 Token Risk API (same proprietary A+–F Safety Read rendered on the HostDeFi token pages, plus pre-graduation on-chain signals for Solana), key purchase/usage endpoints, and the free contract scanner at POST /analyze-token. Keyless callers get a per-IP fair-use tier of 100 calls/day on the verdict endpoints; paid API keys (bought with SOL via POST /v1/keys) raise the quota and unlock batch. Send an API key as the `x-api-key` header.'
