Google Flow API v1

November 17, 2025 (September 11, 2026)

This is the experimental API for Google Flow by Google Labs — generate cinematic AI video and images by driving your own Google Flow account through a REST API.

Models

Model id	Name	Output
`veo-3.1-fast` · `veo-3.1-quality` · `veo-3.1-lite`	Veo 3.1	Video — text-to-video & image-to-video
`omni-flash`	Omni 1.1 Flash	Audio-native video — voices, characters, start + end frames, V2V editing, 10s clips, 360p or 720p
`nano-banana-2-lite`	Nano Banana 2 Lite / Gemini 3.1 Flash-Lite Image	Image — default, all plans
`nano-banana-2`	Nano Banana 2 / Gemini 3.1 Flash Image	Image
`nano-banana-pro`	Nano Banana Pro / Gemini 3 Pro Image	Image

Pick a model per request with the model field. Image generation works on any Google AI plan, including a free account. Video generation needs a paid plan — see Pricing.

Pricing

Third-party Google Flow API by useapi.net vs. the official Gemini API — drive your own Google Flow subscription instead of metered, per-call API billing:

Model	Official Gemini API	useapi.net (Flow Pro)	useapi.net (Flow Ultra)
Veo 3.1 Fast — 8s clip	$0.80	~$0.40	~$0.10
Veo 3.1 Quality — 8s clip	$3.20	~$2.00	~$1.00
Veo 3.1 Lite — 8s clip	$0.40	~$0.20	~$0.05
Veo 3.1 Lite, lower priority	—	—	$0 (Ultra $199)
Omni 1.1 Flash — 8s clip	— (Flow only)	~$0.24	~$0.12
Omni 1.1 Flash — 8s clip at 360p	— (Flow only)	~$0.12	~$0.06
Nano Banana Pro — per image	$0.134	included	included
Nano Banana 2 — per image	$0.067	included	included
Nano Banana 2 Lite — per image	$0.034	included	included

Expected daily output — Ultra ($199/mo) plan. Daily averages observed on top real accounts. These are expected, not guaranteed: Google governs the underlying Flow allowances and they vary with demand.

Free workload (no Flow credits spent)	Avg generations / day*
Veo 3.1 Lite — lower priority video	~1,000
Images — Nano Banana 2 Lite, Nano Banana 2, Nano Banana Pro	up to ~500

*Averages from the busiest real accounts — not guarantees. They are set by Google’s own allowances and fluctuate with demand. Applies only to the free lower-priority video queue and image generation. Credit-metered models (Veo 3.1 Fast / Quality and Omni 1.1 Flash) are not shown here — their volume is bounded by your plan’s monthly Flow credits (see the credit table), not a free allowance.

Veo is billed per second on the Gemini API (an 8-second 720p clip shown) and images are priced per image. Through useapi.net you spend your own Flow plan credits and pay a flat $15/month — image generation is included on any Google AI plan, and there is no Google Cloud project, API key, or per-call metering.

Full per-model credit cost and monthly allowance per tier:

Video generation requires a paid Google AI subscription. Monthly Flow credit allowance per tier:

Tier	Price	Flow credits/mo	~Cost / credit
Plus	$7.99/mo	200	~$0.040
Pro	$9.99/mo first 6 mo, then $19.99/mo	1,000	~$0.020
Ultra $99	$99.99/mo	10,000	~$0.010
Ultra $199	$199.99/mo	25,000	~$0.008

Credit cost per generation and max generations/month per tier. Veo figures come from Google’s official table, Omni figures are measured against the live API. Each cell shows: credits · est. $/gen · max gens/mo.

Start using the API

A single $15/month subscription covers every API on useapi.net — one token, all services. You connect up to 3 of your own provider accounts per service, and useapi.net handles the REST API, load balancing, and polling.

Subscribe — $15/month

Pricing, crypto payment, and volume options — full refund within the first 14 days if you have fewer than 50 successful generations.

Add your accounts again before they stop working

Google is switching off the backend that Google Flow accounts used to run on. Accounts added before 2026-09-16 are still on it and need to be added again.

Check which ones with GET /accounts and read the backend field on each account:

`backend`	What it means	What to do
`flow`	On the current backend	Nothing
`labs`	On the old backend	Add the account again at Setup Google Flow

Adding an account again takes about a minute with the guided browser setup. Your code does not change — same endpoints, same parameters, same responses — and the account keeps its project, characters, voices, credits and original created date.

What already fails on a `labs` account

These four return 404 with the message Flow RPCs have been deprecated and disabled:

Generating images and videos still works on a labs account. That is the part to plan around — Google is retiring the whole old backend, not these four endpoints, so generation stops too once the remaining endpoints are switched off. Google has not published a date, which is the reason to move now rather than wait for one.

Why this is happening

Google moved Flow to flow.google.com on 2026-09-10 and replaced the old authorization with a cookie-based one. On 2026-09-15 it started disabling the old endpoints. Adding an account again captures what the new backend needs.

Captcha & accounts

Image, video, and voice generation require reCAPTCHA — the useapi.net worker solves it automatically. Your first Google Flow account ships with 300 free captcha credits (via CapSolver). After that, add your own provider keys with POST /accounts/captcha-providers (~$0.80–$3.00 per 1,000 solves, or compare provider success rates). Each useapi.net subscription covers 3 Google Flow accounts, up to a hard limit of 50. See Setup → Captcha Providers.
