Create an account and verify email in the website. Buy credits in the website, then create a dedicated API key. A key is bound to that same account, can read balance and create/read/download its jobs, but cannot purchase credits or manage keys. Never paste keys in public pages or source code.
GET /api/me; GET /api/catalog; POST /api/uploads (multipart file); POST /api/jobs (JSON kind,prompt,aspect,voice,upload); GET /api/jobs; GET /api/jobs/{id}; GET /api/jobs/{id}/download.
Send Authorization: Bearer YOUR_KEY. POST /api/jobs also requires Idempotency-Key: a unique 8-100 character identifier. Reuse the same key and identical body on uncertain network retries. Never repeat a generation with a new key just because polling is slow.
Kind: thumbnail. prompt should describe the video title, audience and visual style. Optional upload refers to an image uploaded by this account. Output: 1280x720 PNG. One generation costs40credits; $10 buys1000credits. Never guarantee views or click-through rates. Review headline spelling and likenesses.
MCP methods: initialize,tools/list,tools/call. Tools account,generate(request_id,kind=thumbnail,prompt),job_status(id).
