A context is **sources + a manifest**: upload sources, **curate** them into a searchable index (curate is explicit — there is no auto-curate), and then query the context. The manifest (a single validated JSON document) defines how the context indexes, retrieves, and answers. Conventions: * The `{slug}` path parameter accepts the URL-safe context slug **or** its UUID. * Contexts return a `ContextResponse` (derived flags), not the raw persisted model. Tasks return a `TaskResponse`. * Querying is the unified KnowQL Query API: `POST /api/query` runs one turn (`ask` in, answer out); multi-turn conversations are **sessions** (`GET/DELETE /api/sessions`, `GET /api/queries/{id}`). Read the answer from `output[].content[].text`. * Tasks are a top-level, project-owned resource at `/api/tasks` — they are no longer nested under contexts. Active workflow types are `optimize`, `curate`, `search`, `search_cc`, `search_rag`, `explore`, `profile`, `import`, `pack`, `restore`. servers: - url: https://{host}/api description: Your Nexus deployment host variables: host: default: api.example.com security: - bearerAuth: [] - apiKey: [] tags: - name: Auth description: Login and identity. - name: Project description: The active Pinecone project and its disclosure state. - name: Contexts description: A context is sources + a manifest.
