CREATES a fake-text video: a phone chat conversation that types itself out over a gameplay or green-screen background, with every line read aloud in the voice you pick for that side. It is one of aicut's most-used short-form formats. YOU WRITE THE SCRIPT. There is no script tool and no writer behind this endpoint - the messages array you send IS the conversation that gets made, in that order. Write it yourself from what the user asked for, show it to them as plain text before spending anything, and change it until they like it. Iterating on the script costs nothing. A WORKED EXAMPLE of messages - a four-line chat where the phone's owner is on the right: [{"text":"i saw what you posted","from":"left"},{"text":"and?","from":"right"},{"text":"you told me you were working","from":"left"},{"text":"i was. at his place.","from":"right"}]. That is the whole format: an ordered list of bubbles, each with the line and the side. Write the conversation the way a real one runs - short lines, one thought each, a hook in the first two bubbles, and a last line worth screenshotting. AFTER: the response carries the job id, the price split (generation_tokens for the spoken audio, render_tokens for the video file) and renders_automatically: true. If it ALSO carries start_confirmed: false, the job exists but aicut never saw its start confirmed - do not create it again, watch that job id and tell the user it may need a retry if it has not moved in ten minutes. THAT LAST ONE MATTERS: unlike an AI Video Story there is no fire step and no render step - this one call makes the finished video. Wait for it with wait_for_generation; when it is terminal, get_video carries the file url. REFUSALS (the common ones, not all of them - always read the code you actually get): 400 = the script or a setting is not accepted, and the message says which (an empty line, a missing from, an unknown template or voice, or the whole chat reaching 6000 characters of dialogue, which is the ceiling - shorten it, aicut will not silently cut it for you). 402 = not enough tokens for the whole video; the body carries required and balance. 503 fake_text_unavailable = the video was not started and nothing was charged; retry the same call once. COST: quoted per character of dialogue, in two parts that are both charged - call with estimate_only: true first and state estimated_tokens (the total) to the user. A longer script costs more, AND SO DOES THE VOICE PROVIDER: ElevenLabs is about four times openai/polly per character. Change a provider and re-run estimate_only; never carry an older quote across that change. WHAT THIS TOOL DOES NOT OFFER, so you do not go looking: background music, specific gameplay clips, images or sound effects inside the chat, contact photos, promotions, a second chat in one video, and the cantina skin. Those live in the aicut web app - say so rather than approximating them in the script. (Cloned and custom voices ARE offered - see voice_left / voice_right.) THE WATERMARK is decided by the account's plan, not by this call: free accounts get the aicut mark on the video. Say so if the user asks; there is no argument that changes it. DELIVERY: hand the user ONE thing - the finished video. Do not re-list the script back at them after it is made. SPEND ETIQUETTE (the money grammar): in the webapp the priced button is the user's own finger; in chat YOUR tool call is not - so state the price IN THE SAME MESSAGE as the ask, and the user's explicit go is the button press. Never charge on inference: quoting is not asking, and after a price you wait for the yes. THIS APPLIES TO EVERY TOOL CARRYING THIS NOTE, including this one. A GO IS SCOPED TO ONE PURCHASE, AND IT MUST BE UNAMBIGUOUS. The user's instruction has to NAME the thing you are about to buy, or refer to it so plainly that it cannot mean anything else. A BARE AFFIRMATION - 'go', 'yes', 'ok', 'do it', 'just do it', 'sure' - counts ONLY when ALL THREE of these hold: the message immediately before it was YOUR priced ask for THAT EXACT action, nothing else was raised in between, and NOTHING THE USER ASKED FOR EARLIER IS STILL OUTSTANDING. That last one is the trap the others miss: if the user's OWN previous turn asked for something else - a refusal, a different scene, an edit, a redraw, a question - their 'just do it' may be answering THAT, and it is AMBIGUOUS even when your priced ask happens to be the last thing said in the thread. An ambiguous affirmation is not a go: ask WHICH one they mean and state that price again. WHEN IN DOUBT ABOUT WHAT A 'GO' REFERS TO, ASK. A wrong guess spends the user's money on something they never asked for, and nothing on this surface can undo it or give it back - asking costs one sentence. An episode's STAGES - cast portraits, episode create, fire, render - are each their own priced ask. A STANDING GO IS NOT UNLIMITED: 'just make it' or 'go ahead with the whole episode' authorizes the stages you PRICED IN THAT SAME MESSAGE, in the order you named them, and nothing beyond them - so do not re-ask per stage while it holds, and do not stretch it over a stage whose price the user never saw. IT EXPIRES THE MOMENT THE USER RAISES ANYTHING ELSE - a change, a question, a refusal, a redraw, a new idea - and after that the next stage needs its own priced ask. ONE STAGE IS NEVER COVERED BY A STANDING GO AT ALL: the FIRE (fire_story_video) is irreversible and the biggest single charge in the episode, so it always takes a go that NAMES firing, whatever was said earlier - see that tool's own note. A REDRAW IS NOT A STAGE: regenerate_story_frame and regenerate_cast_portrait are extra spends the user asks for one at a time, so state that price every time, even under a standing go. A standing go never carries to a different episode, and never to generate_video, generate_image or generate_audio - each of those is its own ask. ACCOUNT FOR YOUR OWN CALLS: if the user says something happened that you did not intend - a charge they did not expect, a step they did not ask for - RE-READ YOUR OWN TOOL CALLS IN THIS CONVERSATION before you answer, and tell them plainly which tools you called and when. NEVER SPECULATE ABOUT A CAUSE YOU CANNOT OBSERVE: not a button on an aicut card, not the user's own click, not their client. The aicut cards CANNOT SPEND - the only tools they ever call are the reads (get_video / get_image / get_audio), and their buttons either save a file or send a VISIBLE user turn into the chat - none of them calls a spending tool - so saying a card might have generated or charged something is false, not a hedge. (If a spend followed one of those visible turns, it was still YOUR call, and the honest answer names it.) If your call history disagrees with what you told the user, say what you actually called and let them correct you; do not invent an explanation that makes the two agree. IDEMPOTENCY: idempotency_key is optional and makes a retry safe. Set it on the FIRST call, not only on a retry - the job is addressed by the key, so a key added afterwards cannot find a job that was created without one. Reusing a key REPLAYS the job that key already created and returns it unchanged - even if you send a different prompt or different settings, and even after that job has finished. A key is therefore spent permanently. Do NOT reuse one to make another generation: two deliberate generations are two jobs and need two different keys (or none). ONE EXCEPTION, on render_story_video: replaying a key whose render FAILED answers 409 render_failed rather than replaying the failure, because a spent key stays spent - retry that one with a NEW key or with none. A KEY IS NOT SCOPED TO A TOOL: it addresses a job on the whole account, so reusing the key you gave generate_video on generate_story_video replays that first video instead of starting an episode. One key, one thing you made. (render_story_video is the one door that namespaces its own, which is why an episode's key can be reused on its render without colliding - but there is no reason to reuse it there either.) Never derive the key from the request body. You do NOT need to pass one to be safe against a duplicated delivery: aicut already derives a per-call key server-side, so a retry the transport makes on its own replays rather than charging twice. Pass your own only when YOU want to retry a call whose answer you never saw. OUTPUT: this returns JSON for you to read. When you report back to the user, give them the media URL plus a one-line summary. Do not paste the raw JSON, job ids, or internal field names into the conversation.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| messages | array | yes | The conversation, in order - one entry per chat bubble. This is the script; you write it. |
| contact_name | string | yes | The name at the top of the phone screen - who the owner is texting. A first name or a saved-contact style name ('Mom', 'Jake ❤️'). |
| template | string | no | The chat app skin. Defaults to `imessage`. |
| voice_provider_left | string | no | Which voice service reads the LEFT side. Who speaks this side: `elevenlabs` is the most natural and the web app's own default, `openai` is the cheapest and covers every language with the same eleven voices, `polly` is Amazon's and matches `openai` on price. Defaults to `openai`. IT CHANGES THE PRICE: ElevenLabs costs about four times openai/polly per character of spoken text, so a video priced on one provider is not priced on another - call `estimate_only` again after changing it. |
| voice_left | string | no | The voice reading the LEFT side's lines. Pick two different voices so the two people sound different - there is no silent option, every line is spoken. The voice id for this side, in the provider named by the matching `voice_provider_*`. Leave it out and this side gets that provider's first voice. For `openai`: alloy, ash, ballad, coral, echo, fable, onyx, nova, sage, shimmer, verse - or `list_voices` with `provider: 'openai'` for the same eleven with the labels (age, accent, gender, sound) to match a brief against. For `elevenlabs`: an id from `list_voices` with `provider: 'elevenlabs'` - this account's whole library, stock voices AND its cloned and custom ones, each with a description, labels and a preview link. It is a LONG list and that tool is PAGED (20 an answer by default); when the user has named no particular voice, ask for `usable_for: 'audio', limit: 100` and pick from the 21 stock ones (they work on this door too), and widen only when they want something those do not cover - reading `has_more` before you tell the user a voice does not exist. Call it whenever the user names a voice or a sound; leave the field out otherwise and the side gets aicut's default narrator. For `polly`: any AWS Polly voice id that speaks the chat's `language` - call `list_voices` with `provider: 'polly'`, `language` set to this chat's and `limit: 100`, which returns exactly the voices this door will then accept - PASS THE `limit`, because a common language runs past the default page of 20 (English alone matches 27) and a truncated page reads like the whole set. Joanna, Danielle, Ruth, Matthew, Gregory (US English), Amy, Olivia, Brian (British/Australian English), and others per language. AMAZON DOES NOT COVER EVERY LANGUAGE aicut does (Greek, Hindi, Thai, Ukrainian, Indonesian, Malay, Bulgarian, Croatian, Slovak and Vietnamese have no Amazon voice at all) - the request is refused there and the message says so, so use `openai` or `elevenlabs` for those. Send a voice that does not speak the chat's language and the 400 names the ones that do. Any other id is refused before anything is created or charged - the 400 costs nothing. Cloned and custom ElevenLabs voices ARE accepted here, and on `generate_image_story` - the two create doors that speak. `generate_audio` cannot, which is what `usable_for` on each `list_voices` entry records. |
| voice_speed_left | number | no | The LEFT side's reading speed. How fast this side is read: 1 normal, 1.15 fast, 1.25 very fast. Defaults to 1. It makes the video SHORTER without cutting a word, which is what most short-form chats want - and it costs nothing extra, because the price is per character of dialogue, not per second. |
| voice_provider_right | string | no | Which voice service reads the RIGHT side. Who speaks this side: `elevenlabs` is the most natural and the web app's own default, `openai` is the cheapest and covers every language with the same eleven voices, `polly` is Amazon's and matches `openai` on price. Defaults to `openai`. IT CHANGES THE PRICE: ElevenLabs costs about four times openai/polly per character of spoken text, so a video priced on one provider is not priced on another - call `estimate_only` again after changing it. |
| voice_right | string | no | The voice reading the RIGHT side's lines. The voice id for this side, in the provider named by the matching `voice_provider_*`. Leave it out and this side gets that provider's first voice. For `openai`: alloy, ash, ballad, coral, echo, fable, onyx, nova, sage, shimmer, verse - or `list_voices` with `provider: 'openai'` for the same eleven with the labels (age, accent, gender, sound) to match a brief against. For `elevenlabs`: an id from `list_voices` with `provider: 'elevenlabs'` - this account's whole library, stock voices AND its cloned and custom ones, each with a description, labels and a preview link.

Call it whenever the user names a voice or a sound; leave the field out otherwise and the side gets aicut's default narrator. For `polly`: any AWS Polly voice id that speaks the chat's `language` - call `list_voices` with `provider: 'polly'`, `language` set to this chat's and `limit: 100`, which returns exactly the voices this door will then accept - PASS THE `limit`, because a common language runs past the default page of 20 (English alone matches 27) and a truncated page reads like the whole set.

| voice_speed_right | any | no | The RIGHT side's reading speed. How fast this side is read: 1 normal, 1.15 fast, 1.25 very fast. Defaults to 1. It makes the video SHORTER without cutting a word, which is what most short-form chats want - and it costs nothing extra, because the price is per character of dialogue, not per second. |
| language | string | no | The language the conversation is written in, by name ('English', 'German', 'Spanish'). Defaults to English. Write `messages` in that language too - this field labels the script, it does not translate it. |
| background | string | no | What plays behind the phone: `random` picks a gameplay clip (the usual choice), `greenscreen` leaves a plain background to key out later. Defaults to `random`. |
| aspect_ratio | string | no | Defaults to `9:16` - the vertical shape every short-form platform wants. |
| notification_sounds | boolean | no | Play a message tone as each bubble arrives. Defaults to true. |
| estimate_only | boolean | no | Price these exact settings and create nothing. Returns the token cost, the account balance, and whether the balance covers it. Costs nothing and changes nothing. |
| idempotency_key | string | no | Optional retry-safety key. Read the IDEMPOTENCY note in this tool's description before using one - a reused key returns the first job instead of making a new one. |
