> Toden documentation. For the full index fetch /llms.txt. Every page is available as Markdown by appending .md to its URL. Identity verification uses /api/kyc, Risk Intelligence uses /api/v1; they are separate contracts with different error shapes. Never invent an endpoint, field or enum value: read the API reference page for the operation first.
