Resource identifiers use the physical prefixes emitted by the implementation (`vs_` knowledge base, `vsf_` document, `seed_` web source, `kb-` API-key slug). This spec documents the public REST surface only. Internal helpers (private automations prefixed with `_`) and admin/GDPR lifecycle operations are not part of the public contract. contact: name: Prisme.ai url: https://prisme.ai servers: - url: https://{host}/v2/workspaces/slug:storage/webhooks description: Prisme.ai workspace webhooks variables: host: default: api.studio.prisme.ai description: API host (override for self-hosted or sandbox) security: - BearerAuth: [] - WorkspaceApiKeyAuth: [] tags: - name: Knowledge Bases description: >- Create, list, read, update, and delete knowledge bases (vector-backed document stores). - name: Documents description: >- Ingest and manage documents (uploaded files, web pages, remote files, connector documents) and their indexing. - name: Web Sources description: >- Recurring web crawl seeds that discover and index pages into a knowledge base. - name: Search description: Semantic search over a knowledge base. - name: Access description: Per-knowledge-base access bindings (user, group, org, agent principals). - name: API Keys description: Per-knowledge-base API keys for connector authentication. - name: Stats description: Aggregate dashboard statistics. - name: Skills description: Prompt/instruction registry entries. paths: /v1/knowledge_bases/{knowledgeBaseId}/documents/{documentId}: parameters: - name: knowledgeBaseId in: path required: true schema: type: string pattern: ^vs_[A-Za-z0-9-]+$ maxLength: 128 description: >- Knowledge base id.
