Create a job

POST /v1/generations
Authorization: Bearer cv_live_YOUR_KEY
Content-Type: application/json
Idempotency-Key: 7d1c0f6e-5b0a-4a33-9f2e-0c1b2a3d4e5f

{
  "plan": "credits",
  "model": "veo-3.1",
  "params": { "prompt": "A paper boat on a rainy street", "aspect_ratio": "16:9", "duration": 8 }
}

The response is 201 with the job. A replayed request (same Idempotency-Key and body) returns 200 and the header Idempotent-Replayed: true. See Idempotency.

params takes the prompt and the options of the model (aspect_ratio, duration, resolution). Input images go in params.images as base64 (data) with the MIME type; the request body can be up to 45 MiB. GET /v1/models lists the parameters and the price table of every model.

Job states

Status	Meaning	Can be cancelled
`pending`	Accepted and waiting in the CheapVids queue (your limit of parallel jobs is used up)	Yes, refunded in full
`queued`	Sent to the generator, waiting for a slot	Yes if the generator accepts, refunded in full
`processing`	Being generated	No (`409 not_cancellable`)
`completed`	Done, the result can be downloaded	No
`failed`	Failed, refunded	No
`cancelled`	Cancelled, refunded	No

Each job produces exactly one result. For several variants of a prompt, create several jobs, each with its own Idempotency-Key.

While a job is not finished the response has next: { "action": "poll", "after_seconds": 5 }. Use GET /v1/generations/{id}?wait=60 (Long polling) or a webhook instead of polling in a tight loop. POST /v1/generations/{id}/cancel cancels a job that has not started running.

Download the result

CheapVids does not store the results of API jobs. It relays the file from the generator while you download, for a limited window after the job finishes.

output.url of a completed job is a CheapVids URL: https://api.cheapvids.com/v1/generations/{id}/content?exp=...&sig=.... It works without an API key (for example in a <video> tag) for one hour. Call GET /v1/generations/{id} again to get a fresh URL.
You can also call GET /v1/generations/{id}/content with your API key. Add ?download=1 for a Content-Disposition: attachment response.
Range is supported, one range per request (Range: bytes=0-1048575), so video players can seek. HEAD returns the total size in Content-Length.
The window is results.api_ttl_hours in GET /v1/account (24 hours by default) after completion, and result_expires_at on the job. After it, the endpoint answers 410 result_expired. Download as soon as the job is done.
If the generator no longer serves the file, you get 502 result_unavailable (retry after the Retry-After seconds).

Download limits

To keep the service fast for everyone, downloads are limited per account:

a few streams at the same time (429 with Retry-After: 5 when you are over),
a daily amount of bytes (results.download.user_gib_per_day, with used_bytes_today in GET /v1/account),
a number of downloads per result (results.download.job_download_multiple times the file size per day),
for signed URLs, a limit of requests per minute per IP address.

A download that hits a limit answers 429 rate_limited with Retry-After and details.scope set to bandwidth, job or ip. The bytes of one download count when the transfer runs, so a transfer that already started is never cut.
