  title: Pika Labs via fal.ai Queue Cancel API
  description: 'Pika Labs does not publish a first-party REST API on its main domain.

    Production REST access to Pika''s video generation models is provided

    through the fal.ai inference platform''s standard Queue API.


    Submit an inference request with POST /{model_id}, then poll

    GET /{model_id}/requests/{request_id}/status (or stream it) until the

    request completes, and fetch the result with

    GET /{model_id}/requests/{request_id}. Authentication is a fal.ai API

    key sent as `Authorization: Key $FAL_KEY`.


    The {model_id} path component identifies a specific Pika model on fal.ai

    (for example `fal-ai/pika`). Only the generic Queue API surface is

    modeled here; see the fal.ai documentation under externalDocs for

    model-specific input and output schemas.
