openapi: 3.1.0 info: title: Delphi Audience Clone API version: v3 x-provenance: generated: '2026-07-18' method: generated source: https://docs.delphi.ai/advanced/actions/api-immortal-only.md and the per-resource reference pages (audience, conversations, clone, questions, tags, usage, voice, search). Hand-built from the published REST reference; Delphi does not publish a machine-readable OpenAPI. description: The Delphi API lets you integrate your Digital Mind (an AI clone trained on your content) directly into your own app, platform, or workflow. Create conversations, stream text and voice responses, manage your audience and its contextual memory, organize contacts with tags, search your clone's knowledge base for RAG, and track per-user usage. API access is available on the Immortal plan. All endpoints authenticate with an API key passed in the x-api-key header and are scoped to a single clone. contact: name: Delphi Support email: support@delphi.ai url: https://docs.delphi.ai/advanced/actions/api-immortal-only termsOfService: https://delphi.ai/terms servers: - url: https://api.delphi.ai description: Production security: - ApiKeyAuth: [] tags: - name: Clone description: Retrieve your clone's public profile information. paths: /v3/clone: get: operationId: getClone tags: - Clone summary: Get clone profile description: Retrieve your clone's public profile information. responses: '200': description: Clone profile content: application/json: schema: type: object properties: clone: $ref: '#/components/schemas/Clone' '401': $ref: '#/components/responses/Unauthorized' '429': $ref: '#/components/responses/RateLimited' components: responses: RateLimited: description: Too many requests — 120 requests per 60 seconds per API key exceeded content: application/json: schema: $ref: '#/components/schemas/Error' Unauthorized: description: Missing or invalid API key content: application/json: schema: $ref: '#/components/schemas/Error' schemas: Error: type: object properties: error: type: string description: Error message Clone: type: object properties: id: type: string name: type: string slug: type: string description: type: - string - 'null' headline: type: - string - 'null' purpose: type: - string - 'null' tags: type: array items: type: string imageUrl: type: - string - 'null' initial_message: type: - string - 'null' securitySchemes: ApiKeyAuth: type: apiKey in: header name: x-api-key description: API key scoped to a single clone.
