  title: Brainfish Public Agents Analytics API
  description: "The Brainfish API is organized around REST. Our API has predictable resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.\n\nUse the Brainfish API to programmatically manage your knowledge base, generate AI-powered answers, and integrate Brainfish capabilities into your applications.\n\n---\n\n## Just Getting Started?\n\nCheck out our [Help documentation](https://help.brainfi.sh) for guides and tutorials.\n\n---\n\n## Base URL\n\n```\nhttps://api.brainfi.sh\n```\n\nAll API requests must be made over HTTPS. Calls made over plain HTTP will fail.\n\n---\n\n## Authentication\n\nThe Brainfish API uses API tokens to authenticate requests. You can view and manage your API tokens in your [Brainfish Dashboard](https://app.brainfi.sh) under **Settings → API Tokens**.\n\nAPI tokens have the prefix `bf_api_`. Your API tokens carry many privileges, so be sure to keep them secure! Do not share your API tokens in publicly accessible areas such as GitHub, client-side code, and so forth.\n\nAll API requests must include authentication. Requests without authentication will fail.\n\n| Header | Description |\n|--------|-------------|\n| `Authorization` | Bearer token authentication: `Bearer bf_api_xxxxx` |\n| `agent-key` | Required for AI Agent endpoints only. Find this in your Agents page. |\n\n**Example: Authenticated Request**\n\n```bash\ncurl https://api.brainfi.sh/v1/auth/validate \\\n  -X POST \\\n  -H \"Authorization: Bearer bf_api_xxxxx\" \\\n  -H \"Content-Type: application/json\"\n```\n\n---\n\n## Errors\n\nBrainfish uses conventional HTTP response codes to indicate the success or failure of an API request.\n\n| Code | Description |\n|------|-------------|\n| `2xx` | Success — The request was successful. |\n| `4xx` | Client Error — The request failed due to client-side issues (e.g., missing required parameter, invalid authentication, resource not found). |\n| `5xx` | Server Error — Something went wrong on Brainfish's servers (these are rare). |\n\n**Error Response Format**\n\n```json\n{\n  \"error\": \"validation_failed\",\n  \"message\": \"Request validation failed\",\n  \"validationErrors\": [\n    {\n      \"field\": \"query\",\n      \"message\": \"Query cannot be empty\",\n      \"code\": \"invalid_string\"\n    }\n  ],\n  \"timestamp\": \"2024-01-15T10:30:00Z\",\n  \"requestId\": \"req-abc123\"\n}\n```\n\nThe `requestId` can be provided to Brainfish support when troubleshooting issues.\n\n---\n\n## Rate Limiting\n\nThe API implements rate limiting to ensure fair usage and system stability.\n\n| Endpoint Type | Limit |\n|---------------|-------|\n| Most endpoints | 25 requests per minute |\n| Token revocation | 10 requests per hour |\n\nWhen you exceed the rate limit, the API returns a `429 Too Many Requests` response with headers indicating when you can retry:\n\n- `X-RateLimit-Limit`: Maximum requests allowed in the window\n- `X-RateLimit-Remaining`: Remaining requests in current window\n- `X-RateLimit-Reset`: Unix timestamp when the rate limit resets\n\n---\n\n## Available Resources\n\n| Resource | Description |\n|----------|-------------|\n| **Authentication** | Validate and revoke API tokens |\n| **AI Agents** | Generate streaming AI-powered answers from your knowledge base |\n| **Analytics** | Query conversation thread analytics with filtering and pagination |\n| **Conversations** | Generate follow-up questions for conversations |\n| **Collections** | Organize documents into collections |\n| **Catalogs** | Create catalogs and sync content via API |\n| **Documents** | Create, read, update, and delete documents |\n\n---\n\n## Quick Start\n\n**1. Create an API token** in your Brainfish dashboard under Settings → API Tokens.\n\n**2. Validate your token** to ensure it's working:\n\n```bash\ncurl https://api.brainfi.sh/v1/auth/validate \\\n  -X POST \\\n  -H \"Authorization: Bearer bf_api_xxxxx\" \\\n  -H \"Content-Type: application/json\"\n```\n\n**3. For AI endpoints**, get your agent key from the Agents page.\n\n**4. Generate an AI answer**:\n\n```bash\ncurl https://api.brainfi.sh/v1/agents/answer \\\n  -X POST \\\n  -H \"Authorization: Bearer bf_api_xxxxx\" \\\n  -H \"agent-key: your-agent-key\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"query\": \"How do I reset my password?\"}'\n```\n\n---\n\n## Pagination\n\nList endpoints support pagination using `limit` and `offset` parameters:\n\n| Parameter | Description | Default |\n|-----------|-------------|---------|\n| `limit` | Maximum number of results to return (1-100) | 25 |\n| `offset` | Number of results to skip | 0 |\n\nPaginated responses include a `pagination` object:\n\n```json\n{\n  \"data\": [...],\n  \"pagination\": {\n    \"offset\": 0,\n    \"limit\": 25,\n    \"total\": 42\n  }\n}\n```\n"
