# IntentCast > IntentCast takes a YouTube video, a page URL or a topic, finds live Reddit, Quora and forum threads where that content is the answer, and drafts a reply for each. Replies are reviewed and posted by a person — IntentCast never posts. ## Docs - [API documentation](https://getintentcast.com/docs/api): authentication, starting a cast, checking results, credits, limits and errors - [OpenAPI spec](https://getintentcast.com/openapi.json): machine-readable description of the API (v1) - [Pricing](https://getintentcast.com/pricing): credit packs and the Pro plan - [Terms of Service](https://getintentcast.com/terms-of-service): includes API fair-use rules (no automated posting, no bulk reply generation) - [Refund policy](https://getintentcast.com/refund-policy) ## API in one paragraph Base URL https://smoeblkrgvbrirkagvhu.supabase.co/functions/v1/api. Send "Authorization: Bearer ic_live_..." (keys are created in the app under Account & billing). POST /v1/casts with {"input": ""} returns 202 with a cast id; poll GET /v1/casts/{id} every ~10 seconds until status is completed, empty or failed. Each cast uses 1 credit; empty and failed casts are refunded. Send an Idempotency-Key header so retries are never charged twice. GET /v1/me returns credits, limits and usage. Errors use {"error": {"code", "message", "status"}}. Server-to-server only. ## Contact - support@getintentcast.com
