Pika 2.2 Video Generator | Text to Video

pika/pika-2-2/text-to-video

Produce cinematic 5 to 10-second videos with prompt control, flexible aspect ratios, 720p to 1080p quality, and advanced keyframe tools.

1. Get started

Use RunComfy's API to run pika/pika-2-2/text-to-video. For accepted inputs and outputs, see the model's schema.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/pika/pika-2-2/text-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "promptText": "A mysterious UFO hovers motionless above a quiet, dimly lit city park at night. Its sleek metallic surface reflects the glow of scattered streetlights, while pulsating orange lights along its rim cast a soft, rhythmic glow onto the treetops below. The surrounding lampposts flicker subtly, reacting to the strange electromagnetic energy from the hovering craft. With a smooth and controlled motion, the UFO begins to ascend, drifting diagonally toward the top right of the frame. As it vanishes into the vast starry night sky, the park remains eerily silent, with only the distant hum of the city lingering in the background."
  }'

2. Authentication

Set the YOUR_API_TOKEN environment variable with your API key (manage keys in your Profile) and include it on every request as a Bearer token via the Authorization header: Authorization: Bearer $YOUR_API_TOKEN.

3. API reference

Submit a request

Submit an asynchronous generation job and immediately receive a request_id plus URLs to check status, fetch results, and cancel.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/pika/pika-2-2/text-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{

  }'

Monitor request status

Fetch the current state for a request_id ("in_queue", "in_progress", "completed", or "cancelled").

curl --request GET \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/status \
  --header "Authorization: Bearer <token>"

Retrieve request results

Retrieve the final outputs and metadata for the given request_id; if the job is not complete, the response returns the current state so you can continue polling.

curl --request GET \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/result \
  --header "Authorization: Bearer <token>"

Cancel a request

Cancel a queued job by request_id, in-progress jobs cannot be cancelled.

curl --request POST \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/cancel \
  --header "Authorization: Bearer <token>"

4. File inputs

Hosted file (URL)

Provide a publicly reachable HTTPS URL. Ensure the host allows server‑side fetches (no login/cookies required) and isn't rate‑limited or blocking bots. Recommended limits: images ≤ 50 MB (~4K), videos ≤ 100 MB (~2–5 min @ 720p). Prefer stable or pre‑signed URLs for private assets.
