title: Pika Labs via fal.ai Queue Cancel Submission 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.
