Get Featured on Podcasts. Best Search Tool - Rephonic

# Rephonic API > Comprehensive podcast data API with search, metadata, full transcripts, listener demographics, audience intelligence, and contact information for 4m+ podcasts. Rephonic provides a REST API for accessing structured podcast data. The API is designed for integration with your apps and AI agents. We also provide this as an MCP server at `https://mcp.rephonic.com`, and as an official Python SDK and `rephonic` CLI (`pip install rephonic`). ## Documentation - [Complete API Reference (Markdown)](/llms-full.txt): Full endpoint documentation optimized for LLM consumption - [Developer Portal](/developers): Human-readable API documentation with example responses - [Python Client on GitHub](https://github.com/getrephonic/rephonic-python): Official Python SDK and `rephonic` CLI. Typed wrapper around every endpoint, sync and async. `pip install rephonic` (or `pipx install rephonic` for CLI-only use). ## Authentication All endpoints require the `X-Rephonic-Api-Key` header containing your API key (found on your account page at rephonic.com/account). You will need an Rephonic API subscription (see rephonic.com/developers). Base URL: `https://api.rephonic.com` ## Finding a podcast's Rephonic ID Rephonic has its own internal ID (a slug like `huberman-lab`) for every podcast. To get it, either: - Search by topic/title/publisher via `GET /api/search/podcasts/`, or - **Resolve directly from an external identifier** (Apple/iTunes ID, Spotify ID, YouTube channel ID, or RSS feed URL) via `GET /api/podcasts/lookup/`. If you already have one of those external identifiers, use lookup — you do not need to search first. ## Available Endpoints - `GET /api/search/podcasts/` - Search podcasts by topic, title, or publisher with advanced filters - `GET /api/search/episodes/` - Search episodes across titles, show notes, and full transcripts - `GET /api/search/autocomplete/` - Autocomplete suggestions for search - `GET /api/podcasts/lookup/` - Resolve a podcast from an
