Our API provides powerful tools for extracting web content. ## Overview Supadata offers three main services: * Video Transcripts - Extract transcripts from YouTube, TikTok, Instagram, Facebook, X (Twitter) and video files * Media Metadata - Get social media post data like title, author and engagement metrics * Web Reader - Extract content from any website, crawl pages and extract structured data * YouTube Metadata - Extract video, channel and playlist metadata ## Getting an API Key All requests to Supadata require authentication using an API key. The same key also works with the SDKs and no-code integrations. To get your API key: 1. Sign up for an account at [dash.supadata.ai](https://dash.supadata.ai) 2. Your API key will be generated automatically during onboarding and available in the dashboard ## Integrations and SDKs This documentation provides examples for how to use the Supadata API and its various parameters. We also offer the following SDKs and integrations: * [JavaScript SDK](https://github.com/supadata-ai/js) * [Python SDK](https://github.com/supadata-ai/py) * [n8n](/integrations/n8n) * [Make](/integrations/make) * [Zapier](/integrations/zapier) * [Active Pieces](/integrations/activepieces) * [MCP](/integrations/mcp) ## Documentation for AI If you're working with an AI assistant or vibe coding, we recommend using the "Copy Page" dropdown in top right corner of each page to get AI-ready documentation. Alternatively, give your assistant links to [llms.txt](/llms.txt) or [llms-full.txt](/llms-full.txt). ## Rate Limits API requests are rate-limited based on your subscription plan. Current limits are shown on the [pricing page](https://supadata.ai/pricing). It is possible to increase rate limits upon request. ## API Usage ### Authentication All API requests require authentication using an API key. Include your API key in the request headers: ```bash theme={null} curl -H "x-api-key: YOUR_API_KEY" https://api.supadata.ai/v1/... ``` Never share your API key or commit it to version control. Use environment variables to store your API key securely. Only access the API from a secure server environment. ### Base URL All API endpoints use the following base URL: `https://api.supadata.ai/v1` ### Response Format All API responses are returned in JSON format. # Community Resources The Supadata community has created various resources and guides for using Supadata.
