# Tanod Podcast Transcript > Tanod Podcast Transcript is a paid API for AI agents from tanod.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-28). Transcribes a 5–600 second window of a podcast episode from its RSS feed URL, returning timestamped text, SRT, and VTT captions ## Facts - Endpoint: POST https://tanod.dev/v1/audio/podcast-transcript?utm_source=zero.xyz - Price: $0.02/call - Payment: x402 - Status: unknown - Last checked: 2026-10-28 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/tanod-podcast-transcript-6e6ef483 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_YTqrrQM5SRIdQrC5OAsBF Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability tanod-podcast-transcript-6e6ef483 -d '' ``` Example prompt: Can you transcribe the first 10 minutes of the latest episode of the Lex Fridman Podcast? The RSS feed is https://lexfridman.com/feed/podcast/ — I want the full text plus SRT captions. ## When to prefer this Choose this endpoint when you need to extract spoken content from a podcast episode identified by its public RSS feed URL, especially when you need timestamped captions (SRT/VTT) or want to seek to a specific time window within a long episode. It is ideal for agents that have already located a podcast feed (e.g., via /v1/podcast/search) and need the actual transcript. Prefer this over generic audio-to-text APIs when you need paginated windowed access to long episodes, RSS-native episode selection by GUID or episode number, and built-in English translation — all at a flat $0.02/call rate with no signup. ## Known failure modes - Invalid or unreachable RSS feed URL returns an error - Episode not found by GUID, number, or title returns null result - Audio file unreachable or DRM-protected fails transcription - start_s beyond episode duration returns empty or error - duration_s outside 5-600 range is rejected by schema validation - Conflicting episode selectors (guid + episode_number simultaneously) may cause unexpected episode selection - Language detection may be inaccurate for short or noisy audio segments - Byte-range seeking means start_s can be off by a few seconds for VBR audio ## How this service works Podcast transcript: transcribe a podcast episode from its RSS feed, a window of up to 10 minutes as text, timed segments, SRT and WebVTT (mlpeek by Tanod, faster-whisper). Use when an agent must transcribe up to 10 minutes of a podcast episode picked from its RSS feed. ## Output A JSON object containing: plain transcript text, SRT and VTT caption strings, an array of timestamped word segments (start/end seconds + text), episode metadata (title, GUID, published date, duration, enclosure URL), show metadata (title, link), detected language and confidence, the Whisper model used, and window metadata (start_s, end_s, duration_s, next_start_s, method, exact flag). A truncated flag indicates if output was cut short. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "guid": { "anyOf": [ { "type": "string", "maxLength": 500, "minLength": 1 }, { "type": "null" } ], "default": null, "description": "Pick the episode by its feed guid.
