Uncensored AI APIs — what "uncensored" actually means, and where the walls are

Search for an "uncensored AI API" and you land in a swamp: half the results are general-purpose APIs that will refuse your users mid-story, the other half are anonymous endpoints with no policy, no invoicing entity, no word on where your prompts go and no tomorrow. This post is the map we wish we'd had — and a straight description of where eroq stands.

Refusal walls vs policy walls

Every AI service has a wall somewhere. What matters is which kind.

A refusal wall lives inside the model: at the first dark turn — a murder, a battlefield, a villain who actually menaces — the model breaks character and lectures. It is probabilistic — the same prompt passes on Tuesday and fails on Thursday — so you cannot design a product around it. Your users experience it as the character dying mid-story, and your support inbox experiences what your users experience.

A policy wall lives outside the model: the engine renders what fiction asks for, and a written acceptable-use policy defines the absolute limits — enforced at the account level, not by a filter's mood. It is deterministic, documentable, and you can pass it through to your own users.

"Uncensored" done seriously means the second thing: no filter layered on top of the engine, and a written policy instead of silent refusals. It has never meant "no rules".

What eroq allows, precisely

Our range is set by policy rather than by a filter, and the policy is four paragraphs long:

• Allowed: fiction in every register — horror, crime, thriller, war, satire, grief — across chat, image, video and voice. Your users' stories go where they go; the model stays in character.
• Banned, absolutely: anything involving minors (every character is 18 or older), real, identifiable people without consent (deepfakes, impersonation), and anything illegal. Enforcement is account-level and final.

On the image and video endpoints, a render a provider refuses comes back as an explicit content_blocked error — not a lecture, not a charge, an error code your product can branch on. Chat has no provider refusals to report, because RP+ and RP mini are eroq's own engines with no filter layered on top, built not to refuse fiction in the first place; the hard limits there are enforced as an account-level rule.

Where your prompts go

"Uncensored" answers what renders; privacy answers what is kept. A serious provider is specific about both. On eroq:

• Creations stay private until you publish them. Nothing goes public by default.
• Private mode keeps no file and no prompt. Switch it on in the Studio, or send private: true on the image and video endpoints: no file, no library entry, and the prompt is replaced by stars in the usage ledger.
• eroq's own models retain nothing upstream — RP+, RP mini, Voice One, Voice Turbo, Scribe One, the image models Krea2, Eroq Uncensored, Eroq One and Anima, and Motion One. The third-party video engines (Seedance, Veo, Sora, Kling, Hailuo, Wan, Runway, Grok Imagine) and Flash Image / Flux Image may log prompts at their provider.
• Outside Private mode, prompts are kept in the usage ledger for billing and abuse handling — "uncensored" does not mean "unlogged".

The checklist for choosing an uncensored provider

From building consumer character products ourselves, the questions that actually predict whether an API will carry a product:

1. Is the range written down? If the docs won't say what renders and what doesn't, the sales team's promise won't survive the model's filter. (Ours is one page.)
2. Is there a real entity behind it? Invoices, terms of sale, a jurisdiction. An anonymous endpoint that disappears takes your product with it.
3. Does it say what it keeps? Upstream logging, storage, a private mode — in writing, per model.
4. Do refusals cost you money? Filtered models bill the refusal. Failed or blocked calls here are refunded automatically.
5. Does the roleplay hold at message 200? Permissiveness without persona discipline gives you an agreeable model with no character. Roleplay needs its own tuning.
6. Is pricing predictable under heavy users? Character and story products have the heaviest users in the industry. Flat per-call credits make your P95 user computable; per-token pricing does not.

Your responsibilities as a builder

An uncensored API is a component, not an absolution. Shipping an uncensored product responsibly means: rate your product for the audience it serves, the way any publisher of horror or war fiction does; pass an AUP at least as strict as your provider's through to your users; moderate what gets published (as opposed to generated); tell your users plainly what is kept and where; and keep your payment and platform partners accurately informed about what you operate. The builders who cut these corners are why half this market is a swamp.

FAQ

What counts as an uncensored AI API?

One where fiction renders instead of refusing — its dark, violent and uncomfortable parts included — and where the boundary is written down. In practice that means four things you can check: a published acceptable-use policy that says what is supported and what is not, a deterministic error code when something is out of bounds, a straight answer on what happens to your prompts, and a real company behind the invoice.

Is it legal to build on an uncensored AI API?

Yes — fiction, dark and violent fiction included, is lawful in most jurisdictions, and it is what eroq supports. The hard limits are the same for every customer: fiction only; nothing involving minors, no real identifiable people without consent, nothing illegal. They are enforced at the account level and are not negotiable per customer.

Do blocked or failed requests cost credits?

No. A render blocked on the image or video endpoints returns content_blocked uncharged, and a generation that returns nothing refunds itself automatically. That matters more than it sounds for character and story products, where filtered providers bill you for every refusal your users trigger.

Can I generate uncensored video?

Yes. Motion One is eroq's own uncensored video engine — 60 credits for 5 seconds, 720p, available on every account including free. The third-party engines (Seedance, Kling, Hailuo, Veo) are moderated upstream by their providers: a prompt a provider refuses returns content_blocked and costs nothing, and Motion One is the alternative. Chat (RP+ and RP mini), voice and the image models Eroq Uncensored and Anima are uncensored within policy.

We built eroq because we run consumer character products ourselves and wanted infrastructure that says what it does and does what it says — an uncensored AI API with a roleplay engine, image generation and CDN storage under one written policy, plus a private mode for the renders you would rather we didn't keep. If that is what you are looking for: the quickstart is one curl, and the first 50 credits are free.
