What's in the box — today

The API ships now. The player ships next.

The seek-preview API is the product you can use this afternoon. The Android TV player below is the reference client we're building on top of it — still in development.

One thumbnail size.

320×180 JPEG tiles, always. The format you actually need above a scrubber thumb. About 8KB per tile, packed into sprite sheets your player reads via WebVTT.

Edge-cached.

Sprite sheets are content-hashed and served from Cloudflare's edge cache with immutable headers — a cache hit on every repeat request, without touching the origin.

Try it live · Android TV build

Try Seekr previews on a real remote.

NuvioTV is an open-source, Stremio-style app for Android TV by NuvioMedia. We forked it, wired the Seekr SDK into its scrubber and published a build, so once you've claimed a key you can sideload it and feel the 320×180 thumbnails on a real device. The HUD below is our own reference design for that surface, not a screenshot of the fork.

Cloudflare edge cache. Sprite sheets are stored in Backblaze B2 and served through Cloudflare Workers with immutable cache headers. Once warm at the edge, every subsequent request is a pure cache hit with zero origin traffic.

LifecycleCALL → TILE IN 5 STEPS

Player ready

Before the first seek, your player calls GET /sprites once with the title's IMDB or TMDB ID and video duration. The JSON response is cached for 5 minutes.

Lookup

API key authenticated server-side. The title is matched in the in-memory sprite store — an O(1) map lookup with no database hop.

VTT fetched

JSON returns a relative vtt_url. Player fetches the VTT from sprites.seekr.tv — always served fresh, containing signed sheet URLs (6 h TTL) mapping every timecode to a tile.

Sheet served

Cloudflare Worker validates the signed token, then streams the sprite sheet from Backblaze B2. Sheets are immutably edge-cached for a year after the first request.

Render above thumb

Player extracts the 320×180 tile from the sheet using the VTT's xywh coords. Blit it into the floating frame. The user sees the future.
