01 / TWO WAYS IN
ZSky brings one image-and-video platform to customer experiences, automated workflows, and agent conversations.
REST API
Bring image and video generation to customer apps, internal tools, marketing systems, and creative workflows—without owning the generation stack.
MODEL CONTEXT PROTOCOL
Let users move from conversation to finished media without breaking their flow. The agent can create, follow progress, and bring the result back into the work.
02 / THE OUTPUT
Bring cinematic image and video creation into the moments customers already care about—from creation tools to campaigns to agent-led work.
03 / BUILT DIFFERENTLY
ZSky runs on privately owned hardware in the United States. Prompts and outputs are not used to train models. The same rules apply whether a request starts in the web app, the API, or MCP.
Dedicated GPUs physically operated in the United States—not per-request inference rented from a hyperscaler.
Your prompts and outputs are not used to train models. That commitment is not reserved for a special tier.
API keys are issued only to a signed-in account that paid: a prepaid balance, Pro or Max, straight to your terminal or your settings page. The MCP package downloads from your account.
API and MCP generation use the same content-safety controls as the ZSky web experience.
04 / ACCESS · OPTION 1
One Max subscription opens the web studio plus API and MCP access, with 3,000 seconds of video and 1,000 images included every month. Beyond that, the same per-second rates as pay as you go, up to a monthly cap you set.
$79/mo billed annually
Included seconds and images reset on the 1st of each month (UTC). Create your API key in Settings. Open the docs.
04 / ACCESS · OPTION 2
Video is billed per second of requested output and images per image, from the first call. Two ways in. Prepaid balance, no subscription: add $10, $25, $50 or $100, top up any time, and the balance never expires; turn on auto-recharge to refill when it drops below $2, inside a monthly cap you set. A $50 or $100 purchase may ask you to confirm with your bank. Pro plan ($19 a month): billed at month-end for what you use, never more than the monthly cap you choose between $5 and $1,000.
Fast video up to 1280 px · $0.15 up to 1920 px · $0.20 up to 2560 px · Quality and Cinematic modes priced in the docs
Billed by the seconds you request, 1 to 10 per clip, by the longer side of the rendered frame. A clip that does not fit the remaining Max allowance is billed whole at these rates. Your balance and cap are in Settings → API + MCP.
05 / LIMITS
| Limit | Pay as you go (Pro) | Max |
|---|---|---|
| Included each month | None: pay per use from the first second | 3,000 video-seconds and 1,000 images per calendar month (UTC), at any resolution; Cinematic seconds count double. A clip is included only if it fits whole in the seconds left; otherwise the whole clip is billed at its rate. |
| Video price, per second | Fast: $0.10 per second in HD (longer side up to 1280 px), $0.15 in Full HD (up to 1920 px), $0.20 in 2.5K (up to 2560 px). Quality and Cinematic modes cost more; the docs list their rates. Billed by the seconds you request. Max pays these rates only past the included seconds, when pay per use is on. | |
| Image price | $0.05 per image up to 1,048,576 pixels (1024×1024); $0.08 above that, up to 2048×2048 | |
| Resolution tier | Billed at the tier of the longer side of the delivered video. Fast snaps to a 64-pixel grid (1920×1080 renders as 1920×1088); Quality and Cinematic deliver exact sizes, and a Quality Full HD square is delivered at 1080×1080 and billed HD. | |
| Monthly cap | Pro: required, $10, $50, $250, or any amount from $5 to $1,000. Prepaid balance: optional; it bounds auto-recharge | Optional: $5 to $1,000 |
| What a cap buys | Up to, in Fast HD: $10 = 100 video-seconds or 200 images; $50 = 500 or 1,000; $250 = 2,500 or 5,000 | |
| Billing | Pro and Max: at month-end, to the card on your web subscription, for what you used. Never more than your cap in a calendar month. Prepaid balance: drawn down as you generate; nothing is billed later. | |
| Card on file | Pay per use on Pro or Max needs a card on file from a web subscription (a plan bought in the App Store or Google Play cannot turn pay per use on by itself). Max's included amount and a prepaid balance need no card. | |
| Prepaid balance | No subscription: add $10, $25, $50 or $100, top up any time, and the balance never expires. Each request draws it down at the prices above; a request the balance does not cover is refused, never billed later. Optional auto-recharge refills it when it drops below $2, inside a monthly cap you set. No website plan comes with it. | |
| Monthly reset | 1st of each month, 00:00 UTC. Unused included seconds and images do not carry over. | |
| Request rate | 100 image requests and 100 video requests per minute per account | |
| Daily limit | 200 images and 50 videos per account per day; the count resets at midnight US Eastern time (ask support to raise it) | |
| Concurrent jobs | 1 at a time per account (every key and sign-in on the account shares it) | |
| Unrecognised keys | 20 requests a minute per network (an IPv4 address, or an IPv6 /64) with a key that matches no account, then HTTP 429 rate_limited. A valid key is never slowed by this. | |
| Sign-in codes | POST /v1/pay/start: 10 a minute per network. Up to 5 waiting codes per network and 25 per wider network (an IPv4 /24 or an IPv6 /48); a new code replaces that network’s oldest code whose page was not opened. Each code lasts 15 minutes, and a code whose page was opened is kept for the full 15 minutes. If all 5 are open: HTTP 429 claims_per_client_limit with Retry-After. | |
| Video length | 1 to 10 seconds per clip (10 seconds is the API maximum) | |
| Output size | Images 256 to 2,048 pixels per side; videos 256 to 2,560 pixels per side (2560 px is the API maximum) | |
| Uploads | Image-to-video source image up to 12 MB (PNG, JPEG, or WebP); lip-sync audio up to 10 MB; whole request up to 25 MB | |
| Prompt | Up to 2,000 characters | |
| Results | Signed download link valid 24 hours; outputs kept 7 days | |
MCP calls count exactly like API calls: same key, same allowance, same cap, same limits.
06 / DETAILS
Customer-facing creation tools, internal creative systems, campaign automation, and AI-agent workflows that turn an idea into a finished image or video.
API and MCP access come with Max ($99 a month, with 3,000 seconds of video and 1,000 images included every month) or pay as you go on Pro ($19 a month, billed per second from the first call). They are built for people wiring image and video creation into products, tools, and AI-agent workflows.
Yes. A request without a key gets back a payment path. The agent starts a claim, shows you one sign-in link, and you confirm the code and pick a plan in the browser: pay as you go on Pro, or Max with its included allowance. The key is then delivered to the terminal, never by email or chat.
Three ways: subscribe to Max, subscribe to Pro, or add a prepaid balance of $10, $25, $50 or $100 with no subscription. Each gives you a key in Settings, or straight from the terminal: POST https://zsky.ai/api/v1/pay/start returns a link, you pay in the browser, and the key comes back to the terminal. There is no application.
Video is billed per second of requested output, by mode and by the longer side of the delivered video. Fast is $0.10 per second up to 1280 px, $0.15 up to 1920 px and $0.20 up to 2560 px; Quality and Cinematic cost more, and the docs list their rates. Images are $0.05 each, or $0.08 above one megapixel. Max includes 3,000 seconds of video and 1,000 images every month before those rates apply, with Cinematic seconds counting double; Pro includes none. Either way you set a monthly cap between $5 and $1,000 and generation stops there. New accounts start at up to $50 for the first 7 days, or the full range right away after a $50 or $100 balance purchase confirmed with your bank. With a prepaid balance, each request draws it down at the same rates; top up any time, and the balance never expires.
OpenAI removed the Videos API and the sora-2 models on September 24, 2026. The field-by-field port to the ZSky video API, with Python and curl you can paste, is in the Sora API migration guide.
It downloads from your account: Settings, or with your key from the command line. The package works with no key on first run and walks you through getting one.
