Pika

Generate music, a song with lyrics, or a sound effect from a description, or score a video clip to picture (model pika/pika-audio/pika-soundtrack).

create_audio

Generate an image from a prompt, or from a prompt and reference images up to the model's cap.

create_image

Speak a script aloud with the chosen text-to-speech model and voice, for a voiceover or the audio of a talking_head_studio video.

create_speech

Generate a video from a prompt, a start frame, or reference images, clips and audio. It also animates between a start and an end frame (model pika, image_url and end_image_url), and reframes a clip to a new aspect ratio (model seedance-25, the clip in video_urls, the target aspect_ratio, and a prompt to recompose and extend the frame while keeping the subjects, action, timing and on-screen text).

create_video

Edit a photo from instructions, pinned spots and reference images (mode edit), such as restaging a product photo in a setting from reference_urls. Mode upscale enlarges a photo up to 4x on Topaz.

edit_image

Render the timeline to an MP4 (free). Uses the current revision unless `revision` is given.

export_project

Continue a clip past its last frame with FLUX 3, adding 5-8 seconds of new footage. Takes an MP4 of at most 15 seconds and 50 MB; for a longer clip, cut the span to continue first with video_trim and pass its output url as start_video_url.

extend_video

Use this when you can run a command where the user's file is (their machine, or your sandbox that has it); otherwise upload_file (if offered) or ask_for_media. Returns a presigned URL and a curl command: run it there, never pass the bytes as base64 or text, then pass `media_url` in the app's input. `size_bytes` must be exact; the URL expires at `expires_at`.

prepare_upload

Turn a casual photo of one person into a polished studio headshot, in a template look or a setting you describe.

headshot

List the user's jobs, newest first, with each job's outputs. Pass `next_cursor` back as `cursor` for the next page. Shows nothing to the user; show_creations opens the gallery.

list_jobs

List the user's projects, newest first; pass `next_cursor` back as `cursor`. Shows nothing; show_projects opens the gallery.

list_projects

Search Pika apps and the user's recent creations for the composer's @-mentions.

search_mentions

Animate a character using a video motion reference on Kling 3.0 Motion Control or Pika 3.0 Pose Control. Kling may distort or shorten fast or complex motion.

motion_transfer

Read a project: its timeline as numbered clips, and the items not yet placed.

get_project

Use this when the user wants to see or browse Pika apps. Shows the user a gallery of the apps matching the query (all without one), best match first; read their pick with get_panel.

browse_apps

Score a video clip to picture with Pika Soundtrack: music and foley matched to the action.

pika_soundtrack

Use this when the user wants to choose or change how Pika asks before running. Shows their approval mode for them to pick.

show_settings

Add a person, creature, or object into an existing video from a prompt, optionally guided by an image of what to add.

add_subject_to_video

Animate a photo into a short video with a named Pikaffects effect, such as Cake-ify, Crumble, Explode, or Levitate.

add_photo_effect

Render one segment of a video podcast episode with Seedance 2.5 and native audio, from the dialogue you planned for it, with host and guest photos as identity references (text-to-video without photos). Run it once per segment, same continuity_id, segment_index 0, 1, …; assemble the segments in order on v1 of a project.

podcast_creator

Make a product ad from product photos and a screenplay you write: the whole ad, up to 30 s, renders as one Seedance 2.5 take with native music, voiceover and talking characters, and needs no assembly.

product_ad

Read where the user last was in the Pika view opened from one tool result. Free.

get_view_place

Use this when the user says they uploaded or picked something in a Pika panel, or asks you to use their selection, which may not reach the chat. `status` is waiting, with `state` null, until they choose; a panel_id that isn't the user's fails with NOT_FOUND.

get_panel

Relight a photo or a video clip with a preset lighting rig, up to three placed lights, or a description, keeping the subject and composition.

relight_media

Remove clips from the timeline at `revision`; later v1 clips close the gap. Returns the new numbered timeline.

remove_clips

Rename a project.

rename_project

Save what the user uploaded or picked in a panel, so the panel restores it and get_panel reads it. Free. Pass the revision you last saw as expected_revision so an older copy's late save can't overwrite a newer pick; a stale one fails with REVISION_CONFLICT carrying the current `revision`.

save_panel

Replace the whole timeline at `expected_revision`, keeping each given clip_id. For the timeline view; the model uses add_clips, update_clip, remove_clips and update_timeline.

save_timeline

Save where the user is in the Pika view opened from one tool result, so reopening it returns there. Free.

save_view_place

Render consecutive beats of a short film's shot list as one continuous clip on the selected video model, locked to the cast stills; each beat runs clamp(round(length_sec / beats), 4, 15) s and a clip at most 30 s for Seedance 2.5 or 15 s for Seedance 2.0 and MiniMax H3. MiniMax H3 uses 720p (768P); Seedance supports 480p, 720p and 1080p. Cast stills come from create_image or edit_image outputs, the score from create_audio. Assemble the film in a project: clips in beat order on v1 at their start times (first_beat × beat seconds), the score from 0 on a2.

short_film

Show the user a gallery of their projects, most recently updated first. They can open one in Pika or pick one to work in; read their pick with get_panel.

show_projects

Use this when an app field the user hasn't chosen takes ids from list_presets, including the app's built-in choices (camera moves, voices). Shows the user a picker of one collection, with thumbnails, and lists them for you by id and name; read their pick with get_panel. When the tool also takes a `prompt`, presets are optional: a look the user describes works instead.

list_presets

Adapt one photo, poster or ad to a new aspect ratio, reframing the subject and always reflowing existing text while preserving original copy and branding.

resize_images

Create a project to collect clips for one video. Its timeline starts empty at 1080x1920@30.

create_project

Reshoot a video clip with Seedance 2.5, swapping the characters, outfits, location or products for reference images while the motion, camera, performance and audio stay as filmed.

swap_anything

Lip-sync a face to speech: one portrait and one audio track become a talking-head video. The face can be the user's photo or a headshot or create_image output; the audio can be the user's recording or create_speech output.

talking_head_studio

Upload a file's bytes from the upload view and return its `media_url`. Free.

upload_media_bytes

Use this when the host can pass the user's file (such as a chat attachment) as `file`: Pika copies it and returns its `media_url` for an app's input. Images, video and audio only. Free.

upload_file

Use this for the user's image, video or audio file that you can't upload yourself with upload_file (if offered) or prepare_upload. Shows the user an upload panel; read what they uploaded with get_panel. Pass each `media_url` as is in an app's input: the app reads the file, so don't open or download it. To use part of it ("the first guy"), say so in the app's prompt or brief. Free.

ask_for_media

Upscale a photo up to 4x or a video to 1080p or 4K with Topaz.
