Results are project-scoped server-side and returned as compact trace summaries. ## OpenAPI ````yaml https://api.veryfront.com/openapi.json get /projects/{project_reference}/traces openapi: 3.1.0 info: title: Veryfront REST API version: 1.0.0 summary: Domain-first REST reference for the maintained Veryfront HTTP API surface. description: >- Project-first HTTP API for Veryfront project resources. 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: - url: https://api.veryfront.com description: Current request origin - url: http://localhost:4000 description: Local development security: - bearerAuth: [] - apiKeyAuth: [] tags: - name: Projects description: Core project operations - name: Account description: >- Transitional account-level users and settings retained for dashboard compatibility - name: Project Users description: Project members and invites - name: Members description: Project members and invites - name: Files description: Main branch files - name: Branch Files description: Files on branches - name: Environment Files description: Files in environments - name: Release Files description: Files in releases - name: Uploads description: File uploads and assets - name: Branches description: Content branches for previews - name: Releases description: Published file snapshots - name: Deployments description: Connect releases to environments - name: Environments description: Deployment targets and variables - name: Environment Variables description: Project environment variable management - name: Domains description: Custom domains for environments - name: Project Servers description: Project-scoped dedicated server instances - name: Root Servers description: >- Transitional root dedicated-server administration retained for compatibility - name: Tasks description: Project tasks - name: Evals description: Project eval definitions and eval run projections - name: Work description: Project business-process definitions and execution state - name: Workflows description: Project workflows - name: Workflow Runs description: Workflow run history and status - name: Schedules description: Recurring project automation schedules - name: Webhooks description: Webhook-triggered automation entry points - name: Skills description: Project skills - name: Prompts description: Project prompts - name: Tools description: Project tools - name: Resources description: Project-defined resource documents and source-backed resource definitions - name: Sandboxes description: Ephemeral sandbox execution environments - name: Search description: Text and vector search - name: Knowledge description: Knowledge manifest lookup across project knowledge files - name: Chunks description: File chunks for search indexing - name: Embeddings description: Vector embeddings - name: RAG Documents description: Project retrieval-augmented knowledge documents - name: Style Artifacts description: Project style artifact state and build outputs - name: External Storage description: Transitional connected cloud-provider file operations - name: Project Cache description: Project-scoped distributed cache operations - name: User Cache description: Transitional user cache helpers retained for compatibility - name: API Keys description: >- Transitional user/account API key management;
