Payment outcome follows the selected rail's settlement policy. **Catalog:** [YouTube Video Transcript (Provenance) pricing and uptime](https://getanyapi.com/api/youtube/video-transcript-full) - live USD price, lane routing, and measured 30-day uptime. [Every YouTube endpoint](https://getanyapi.com/api/youtube). ## OpenAPI ````yaml /openapi.json post /v1/run/youtube.video_transcript_full openapi: 3.1.0 info: contact: email: support@getanyapi.com description: >- Any API, one wallet, USD, no subscriptions. Each API is a single discovered operation: send the normalized input, get a normalized result. Prices and payment outcomes are reported in USD; each operation documents the settlement policy for its enabled payment rails. title: AnyAPI version: 1.0.0 x-guidance: >- Use each operation's published method and path with its normalized JSON input (see the operation requestBody). Before setting a client or tool timeout, GET /v1/apis/{sku} and inspect its trailing-30-day latency p50/p95/p99 and sample; p99 is an observation, not a maximum. To pay: send your AnyAPI key (Authorization: Bearer, billed from your USD wallet). For operations that advertise an inline rail, pay per call inline with x402 - call with no key, receive HTTP 402 with a PAYMENT-REQUIRED header, then retry with the PAYMENT-SIGNATURE header (base, no account needed); or pay per call inline with MPP (Machine Payments Protocol) - call with no key, receive HTTP 402 with a WWW-Authenticate: Payment challenge, then retry with the Authorization: Payment header (tempo, no account needed). x402 settles after execution; execution failure is reported as released; mpp settles before execution; execution failure is reported as charged_undelivered. servers: - url: https://api.getanyapi.com security: - bearerAuth: [] - apiKeyAuth: [] tags: - name: ahrefs x-group: Ahrefs - name: airbnb x-group: Airbnb - name: alibaba x-group: Alibaba - name: amazon x-group: Amazon - name: apollo x-group: Apollo - name: appstore x-group: Appstore - name: bluesky x-group: Bluesky - name: booking x-group: Booking - name: capterra x-group: Capterra - name: chatgpt x-group: Chatgpt - name: coinmarketcap x-group: Coinmarketcap - name: company-enrichment x-group: Company_enrichment - name: company-search x-group: Company_search - name: congress x-group: Congress - name: dexscreener x-group: Dexscreener - name: douyin x-group: Douyin - name: ebay x-group: Ebay - name: email x-group: Email - name: email-finding x-group: Email_finding - name: email-verification x-group: Email_verification - name: facebook x-group: Facebook - name: fiverr x-group: Fiverr - name: g2 x-group: G2 - name: gemini x-group: Gemini - name: github x-group: Github - name: glassdoor x-group: Glassdoor - name: google x-group: Google - name: google-ads x-group: Google Ads - name: google-finance x-group: Google Finance - name: google-shopping x-group: Google Shopping - name: hackernews x-group: Hackernews - name: indeed x-group: Indeed - name: instagram x-group: Instagram - name: linkedin x-group: Linkedin - name: maps x-group: Maps - name: mobile-phone x-group: Mobile_phone - name: naver x-group: Naver - name: pandaexpress x-group: Pandaexpress - name: people-search x-group: People_search - name: perplexity x-group: Perplexity - name: person x-group: Person - name: person-enrichment x-group: Person_enrichment - name: pinterest x-group: Pinterest - name: playstore x-group: Playstore - name: polymarket x-group: Polymarket - name: realtor x-group: Realtor - name: reddit x-group: Reddit - name: redfin x-group: Redfin - name: rednote x-group: Rednote - name: sec x-group: Sec - name: semrush x-group: Semrush - name: seo x-group: Seo - name: snapchat x-group: Snapchat - name: social x-group: Social - name: spotify x-group: Spotify - name: substack x-group: Substack - name: threads x-group: Threads - name: tiktok x-group: TikTok - name: tiktok-shop x-group: TikTok Shop - name: tripadvisor x-group: Tripadvisor - name: trustpilot x-group: Trustpilot - name: truthsocial x-group: Truthsocial - name: twitter x-group: X (Twitter) - name: upwork x-group: Upwork - name: walmart x-group: Walmart - name: web x-group: Web - name: weibo x-group: Weibo - name: yahoo-finance x-group: Yahoo Finance - name: yelp x-group: Yelp - name: youtube x-group: YouTube - name: zhihu x-group: Zhihu - name: zillow x-group: Zillow paths: /v1/run/youtube.video_transcript_full: post: tags: - youtube summary: YouTube Video Transcript (Provenance) description: >- Fetch a YouTube transcript with timed segments and its provenance: whether the words are creator-written captions or machine speech recognition. **Price:** billed per result - \$2.94 per 1,000 requests base + \$0.00 per 1,000 results, capped at \$2.94 per 1,000 requests. **Routing:** one lane serves this API today, so a failed attempt has nowhere to fail over to.

Comma-separated keys (dotted paths like `author.name` descend into nested objects) to keep on each result item.
