Pages are captured above the fold; social posts are cropped to their embed card. Set scroll=true to record a scrolling web page as video (ignored for social posts). Returns a finished image or video library item with a sourceId for overlays or layout media. Unlike AI generation, capture completes in this request, with no polling; allow up to two minutes. Private pages and social profiles/feeds are not supported. Use an Idempotency-Key when retrying to avoid duplicate captures. ## OpenAPI ````yaml /openapi.json post /v1/library/screenshots openapi: 3.0.3 info: description: >- The Tella Public API allows you to programmatically access your videos and playlists, including transcripts, chapters, and thumbnails. ## Authentication All requests require a Bearer token in the Authorization header: ``` Authorization: Bearer tella_pk_xxxxx... ``` API keys can be generated in your Tella workspace settings. ## Rate Limiting The API is rate-limited to 100 requests per minute per user within a workspace. Rate limit information is returned in response headers: - `RateLimit-Policy`: Named quota, request limit, and window in seconds - `RateLimit`: Remaining quota and seconds until reset - `X-RateLimit-Limit`: Maximum requests per window - `X-RateLimit-Remaining`: Remaining requests in current window - `X-RateLimit-Reset`: Unix timestamp in milliseconds when the window resets A `429 Too Many Requests` response also includes `Retry-After` in seconds. title: Tella Public API version: 1.0.0 servers: - description: Production url: https://api.tella.com security: [] tags: - description: Video operations name: Videos - description: Sections of a video name: Clips - description: Playlist operations name: Playlists - description: Sidebar groups for organizing playlists name: Playlist Groups - description: Tags for categorizing and filtering videos name: Tags - description: >- Viewing analytics for a video or across the workspace: plays, watch time, retention, geography, referrers name: Analytics - description: Personal, workspace, and default video backgrounds name: Backgrounds - description: >- Reusable media saved to a workspace, plus Tella's curated sound effect and background music catalogs — the same items the editor's media panels show name: Library - description: Webhook endpoint management name: Webhooks externalDocs: description: API versioning and deprecation policy url: https://www.tella.com/docs/versioning paths: /v1/library/screenshots: post: tags: - Library summary: Capture a web page or social post description: >- Captures a public web page or a single post on X, Instagram, LinkedIn or TikTok and saves it to the caller's private library.
