Root account/platform endpoints that still appear in this reference are transitional compatibility surfaces unless the canonical inventory marks them otherwise. ## Start here - **Interactive REST reference:** [/docs](/docs) - **Raw OpenAPI document:** [/openapi.json](/openapi.json) - **Canonical inventory:** `docs/api-surface-inventory.md` in this repository - **GraphQL endpoint:** [/graphql](/graphql) - **MCP playground:** [/mcp/playground](/mcp/playground) ## Authentication Use one of these request headers: - `Authorization: Bearer ` - `Authorization: Bearer vf__` - `X-API-Key: vf__` JWTs must use the Bearer token contract. API keys work in either the Bearer header or `X-API-Key`. ## Discovery model Veryfront is one platform with multiple access modes: - **REST** for resource-oriented and operational HTTP workflows - **GraphQL** for connected app-facing data and typed mutations - **MCP** for tool-style automation and agent workflows For the fastest path through the platform, start with the project-scoped domain groups. Transitional account/platform groups are retained for compatibility and follow the removal register in the canonical inventory. contact: name: Veryfront API Support url: https://veryfront.com/docs email: support@veryfront.com servers: -
