AI UGC Video Generator API Pricing for 5 Tools in 2026

Every major AI UGC video generator now ships an API, and at every one of them the API is a separate product with separate economics. MakeUGC sells API credits 34 percent cheaper than the same credits in its app. HeyGen runs the API on a wallet that is completely independent of your subscription balance. Higgsfield offers MCP and CLI but excludes the unlimited models its plans are sold on. Creatify sells API plans at $99 and $299 that its main pricing page never mentions, and Arcads documents an API while publishing no price at all. All five pricing surfaces were first read on August 29, 2026, and HeyGen, Creatify and Arcads were read again on October 7, after HeyGen replaced its API price list.

If you are building automated creative into a product, an internal tool, or an agency pipeline, the number on the pricing page is almost never the number you will pay. The app price and the API price are set separately, they move in different directions, and in one case they do not even draw from the same balance.

Here is what each vendor actually publishes, with the arithmetic done.

Which AI UGC video generators have an API?

How much does an AI video generation API cost?

Between $5 to open an account and roughly $300 a month for production volume, depending on how the vendor meters the work. Three vendors in this group publish a straight API price: MakeUGC, at $99 a month for 2,000 credits and $299 for 6,000, Creatify, at $99 for 500 credits and $299 for 2,000, and HeyGen, which sells no plan at all and lets you top up a wallet from $5. Higgsfield and Arcads price the API off the same subscription ladder the app uses, so the real question becomes what a credit buys.

That is the number to chase, because the headline prices in this category are not comparable to each other. A credit means six seconds of avatar video at Creatify's API rate and about 0.7 seconds of Kling 3.0 at Higgsfield's. Convert everything into cost per finished 30 second ad before you compare, and the ranking changes.

The MakeUGC API is 34 percent cheaper than the MakeUGC app

This is the most useful finding in the group, and it is sitting on the same page as the app prices, one tab across.

MakeUGC's Platform tab prices Pro at $149 a month for 2,000 credits. Its API tab prices API Starter at $99 a month, discounted from a $149 list, for the same 2,000 credits. Identical allowance, 500-plus AI creators, batch mode, product in hand. That is 7.45 cents a credit on the app against 4.95 cents through the API, a 33.6 percent reduction for buying the same thing through a different door.

Two details make that worth acting on. First, the API tab's second rung, API Pro at $299 for 6,000 credits, works out at 4.98 cents, which is fractionally more than the entry rung. There is no volume break between the two API plans, so the discount is for using the API at all, not for using it heavily. Real volume pricing starts at Enterprise, which the page describes as volume-based with a white-label license and developer support over Slack.

Second, the Platform ladder lists API access as an Enterprise perk. So if you only read the app tab, you would conclude that programmatic access requires a sales call, when in fact it is $99 self-serve on the tab beside it. The full MakeUGC plan breakdown has the rest of the ladder, including the credit expiry rules.

Are MCP credits and API balance the same?

No, and HeyGen answers this in its own API FAQ in those exact words. Its wording is worth quoting because nobody else in the category is this explicit: "MCP usage is deducted from your web plan's premium credit balance, while Skills and Direct API usage is deducted from your API dashboard balance. The two billing pools are independent."

Read as a buyer, that means a HeyGen subscription buys you zero direct API capacity. The two are separate purchases. HeyGen sells three integration paths and they do not bill alike. MCP authenticates over OAuth with no keys and requires an active web plan with premium credits, drawing down the subscription you already pay for. Skills and Direct API authenticate with an API key in an X-Api-Key header and draw down a separate API wallet you top up independently.

The upside is that the wallet has no floor worth worrying about. HeyGen states you can "start with as little as $5" and pay only for what you use, with no monthly commitment. For prototyping, that is the cheapest genuine entry point in this comparison.

HeyGen API price and credits

HeyGen now publishes its API rates, in a help article stamped 16 September 2026, and they are not the rates most guides quote. Video is billed by the second at a flat 5 cents a credit: $0.60 a minute for an Avatar III digital twin, $0.99 for a stock or photo avatar on Avatar III, $2.31 for an Avatar IV photo avatar, $4.83 for an Avatar IV digital twin or studio avatar, and $7.20 for Avatar V. A 30-second ad therefore costs between 30 cents and $3.60 depending on the engine. There are no free API credits, and the balance expires 12 months after purchase.

The catch is the gap to the web app. An Avatar IV video uses 31 credits a minute in the app and 97 through the API, so the same clip costs about three times as much when code makes it. The September list also raised Avatar V by 80 percent and Video Agent from $2.00 to $5.82 a minute. The full table, the old and new prices side by side and the limits are in our HeyGen API pricing breakdown, and the web plan credit rates are covered separately.

Can you use an unlimited plan through an API?

No, at every vendor that sells one. This is the trap that catches teams who buy a plan for its unlimited generation and then try to automate against it.

Higgsfield states the exclusion on its pricing page, verbatim: "Unlimited models and Free Generations on plans are accessible only via higgsfield.ai and are not accessible on MCP/CLI, Canvas or Supercomputer." So the single feature its plan cards are marketed on is precisely the feature the programmatic surface loses. Through MCP or the CLI you are back on metered credits at the published rate, which on the $47 Plus plan is 3.92 cents each, or about $1.65 for a 30 second Kling 3.0 ad at 720p.

That is still competitive, and Higgsfield is the only vendor here whose API cost you can calculate exactly before you write a line of code, because it publishes a per-model, per-resolution rate card. The pattern holds across the category, though: unlimited is a web-app feature everywhere we have checked, and it comes with several other limits that are not in the headline, including the render queue it puts you in.

Higgsfield also runs a separate developer platform at open.higgsfield.ai, read on October 7, 2026, that drops plans and credits altogether. It is pay per generation with no subscription or seat fee, priced per second by model: Kling 3.0 from about 8 cents a second at list, Seedance 2.0 from about 14 cents and Seedance 2.5 from about 21 cents, with volume discounts applied automatically. A 30-second Kling 3.0 clip is therefore roughly $2.50 at list before any discount. How many jobs run at once depends on the funds you added in the last 28 days, from 2 by default to 40 at $1,000. The full model-by-model rate card, the break-even against a plan and the models the API leaves out are in our Higgsfield API pricing guide.

Creatify prices its API in the docs, and Arcads does not price it at all

Creatify has a full API product, with programmatic access to its Aurora avatar model and its UGC avatar library. The pricing page has an API tab with the two plans, and the per-endpoint rates are in the developer documentation (our Creatify API pricing guide lists every endpoint): API Starter at $99 a month for 500 credits and API Pro at $299 for 2,000, with Enterprise quoted. An avatar video or a URL to video job costs 5 credits per 30 seconds, plus one credit per product link, so a 30-second ad is 99 cents on Starter and 75 cents on Pro. That is half the app's meter, which charges 5 credits per 15 seconds, so here the API is the cheaper way to buy the same video.

Arcads is the harder case. It has a real API, documented at external-api.arcads.ai/docs, plus an MCP server at mcp.arcads.ai. Its terms say the API is accessible only on a Customized offer, the app lists API access under the Pro, Scale and Business plans, and API calls draw on the same credit balance as the app. It also has no pricing page: arcads.ai/pricing returns a Not Found error and there is no pricing link in the site navigation (checked again 7 October 2026). Authentication is a Client ID and Client Secret over HTTP Basic, and a 30-second clip is billed as a full minute because length is rounded up. What Arcads does publish is the meter, 800 credits per minute per actor for talking actor video, and the app's plan list runs Starter at 8,000 monthly credits, Creator at 16,000, Pro at 40,000, Scale at 80,000 and Business at 160,000. Starter and Creator are blocked at the limit until renewal, while Pro and above bill overage per extra credit and roll unused credits over. Dollar prices are only reported by third parties, with Pro at $550 a month at list. We cover access, endpoints and the licence terms on our Arcads API page, and what the plans mean for buyers in the Arcads pricing breakdown.

Do API credits roll over?

Mostly not. MakeUGC's FAQ is explicit that credits refresh each billing cycle and do not roll over, with unused credits expiring at the end of the month. Higgsfield prints "Fixed amount of 1,200 credits/mo" on the plan card itself. Arcads is the exception at the top of its ladder: credits on Starter and Creator do not carry over, but its help center says unused credits on Pro, Scale and Business roll over and accumulate, and those are the plans that list API access. HeyGen's API wallet is a different kind of exception, since it is a prepaid balance rather than a monthly allowance, and that balance expires 12 months after purchase.

For a production pipeline that matters more than it does for a person clicking buttons. Automated creative generation is bursty by nature, because it spikes around launches and campaign refreshes and goes quiet in between. A monthly allowance that resets means you are sizing your plan for your worst week and paying for it fifty two times a year. Prepaid balances and true volume pricing suit that shape better, which is one reason the Enterprise tiers exist at all.

What to check before you commit to an API

Four things, in this order.

Work out the cost of one finished 30 second ad, not the cost of a credit. That is the only unit that compares across vendors, and it is the only one your finance team will recognize. Then check whether the plan feature you are buying survives the jump to the API, because unlimited generation does not. Then check the seat and concurrency limits, since MakeUGC's API Pro sells 5x concurrency as its main upgrade over API Starter and concurrency, not credits, is usually what caps a batch job.

Finally, put your own monitoring on the render endpoint. These are long-running asynchronous jobs behind a queue that every vendor reserves the right to slow down at peak, and a generation endpoint that starts timing out mid-campaign is not something a status page will tell you about in time. A simple uptime check on the API endpoint itself, running every minute from more than one region, will surface it before your creative calendar does. Vendors publish status pages for outages, not for degradation, and degradation is what actually breaks a nightly batch.

The short version

Use HeyGen's $5 wallet to prototype, because nothing else in the category lets you start that small. Use the MakeUGC API tab if you want a self-serve monthly plan, because at 4.95 cents a credit it is the cheapest published API rate here and it undercuts the same company's own app by a third. Use Higgsfield if you need to model your costs precisely before you build, because its per-model rate card is the only one in the group you can multiply out, and read the Creatify and Higgsfield comparison if you are also weighing the app side. Use the Creatify API if you want the lowest published price for a presenter ad from a product link, at 75 to 99 cents per 30 seconds. Treat Arcads as a sales conversation rather than a self-serve option, because its terms tie the API to an offer agreed on a call and it prints no price.

And if what you actually need is finished ads rather than an integration project, the shortest path is still to skip the pipeline. Paste a product URL into the generator above and you get back a batch of creator-style ad scripts with the angle and the hook already written, and on a paid plan the ones you pick are rendered as vertical, captioned videos. For the wider price landscape, our AI UGC ad generator pricing comparison covers the app ladders across the category, and the TopView and Higgsfield head-to-head goes deeper on cost per second if that is the axis you are optimizing.
