Requires the API key of the account that created it. NagaAI keeps the file for a limited time after the job completes. ## OpenAPI ````yaml /openapi/naga-api.json get /v1/videos/{id}/content openapi: 3.1.0 info: title: NagaAI API description: >- NagaAI routes inference requests to a pool of upstream providers behind one endpoint. Requests speak the OpenAI or the Anthropic dialect, and the gateway selects a provider that serves the requested model. Two credentials exist and they are not interchangeable. An API key reaches models. A provisioning key manages the account: its keys, its balance, and its usage. Each operation declares which one it accepts. NagaAI charges the account in credits for the tokens a request consumes, at the published price of the model that served it. One credit costs one US dollar. termsOfService: https://naga.ac/legal/terms contact: name: NagaAI url: https://naga.ac version: '2026-03-31' summary: >- One API to many model providers, in the OpenAI and Anthropic request formats. servers: - url: https://api.naga.ac description: Production security: [] tags: - name: Chat Completions description: >- The OpenAI Chat Completions dialect, with streaming, tools and multimodal input. externalDocs: url: https://platform.openai.com/docs/api-reference/chat description: The OpenAI reference for this dialect. - name: Messages description: >- The Anthropic Messages dialect, as Claude-style clients and agents speak it. externalDocs: url: https://docs.anthropic.com/en/api/messages description: The Anthropic reference for this dialect. - name: Responses description: >- The OpenAI Responses dialect, with structured input, tools and streamed output items. externalDocs: url: https://platform.openai.com/docs/api-reference/responses description: The OpenAI reference for this dialect. - name: Embeddings description: Vector embeddings for search, retrieval, clustering and ranking. externalDocs: url: https://platform.openai.com/docs/api-reference/embeddings description: The OpenAI reference for this route. - name: Images description: Image generation and editing with multimodal models. externalDocs: url: https://platform.openai.com/docs/api-reference/images description: The OpenAI reference for these routes. - name: Audio description: Speech from text, and text from uploaded audio. externalDocs: url: https://platform.openai.com/docs/api-reference/audio description: The OpenAI reference for these routes. - name: Videos description: 'Video generation as a job: submit it, poll it, download the file.' externalDocs: url: https://docs.naga.ac/api/videos description: The NagaAI guide to video generation. - name: Moderations description: Safety classification of text and image input. externalDocs: url: https://platform.openai.com/docs/api-reference/moderations description: The OpenAI reference for this route. - name: Models description: The catalog of models, their capabilities and their prices. externalDocs: url: https://platform.openai.com/docs/api-reference/models description: The OpenAI reference for this route. - name: Startups description: The organizations whose models the catalog carries. externalDocs: url: https://docs.naga.ac/get-started/models description: The NagaAI guide to the model catalog. - name: Account description: The account's balance and its usage, behind a provisioning key. externalDocs: url: https://docs.naga.ac/account/balance-and-activity description: The NagaAI guide to balance and activity. - name: API Keys description: The account's API keys, behind a provisioning key. externalDocs: url: https://docs.naga.ac/account/api-keys description: The NagaAI guide to API keys. paths: /v1/videos/{id}/content: get: tags: - Videos summary: Download a video description: >- Redirects to the MP4 file of a completed job.
