How do I start generating adult content with an API?

Create an account on Api18.dev, generate an API key in the dashboard, then POST a JSON body with your prompt and a model id to /v1/generate?wait=true using an Authorization: Bearer header. The response contains the output URL. No content filter is applied to your prompt.

Do I need a credit card to start?

No. New accounts receive $10 in free credit usable in the dashboard playground without a card. To call the API programmatically you add paid balance, which you top up in USDT on Solana or Tron.

Is the generated content filtered or watermarked?

Prompts are not content-filtered and outputs are not watermarked by the API. You are responsible for using outputs lawfully and within Api18.dev's terms (no illegal content).

How to Generate Adult Content with an API (No Restrictions)

Generating adult content through an API is the same three steps as any generation API — get a key, send a request, read the result — with one difference: there is no prompt filter rejecting the request. This walkthrough takes you from zero to a working uncensored generation call with Api18.dev.

Step 1 — Create an account and get a key#

Sign up with an email (no card required) and open the API keys page in the dashboard.
Create a key. It looks like api18_ followed by 16 characters. Copy it once and store it as an environment variable — API18_KEY.
Keep the key server-side. Never ship it in client-side code.

Step 2 — Send your first request#

Use the one-call endpoint POST /v1/generate?wait=true. Provide a model id (from the models page) and your prompt. No content moderation is applied to the prompt.

curl -X POST "https://api18.dev/v1/generate?wait=true" \
  -H "Authorization: Bearer $API18_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "<image-model-id>",
    "prompt": "your prompt here"
  }'

# → returns the finished job; the image URL is at .data[0].url

Step 3 — Read the result#

The response is the finished job. The output URL is at data[0].url. Image models return an image; video models return a clip. The job also reports cost_usd, status, and an expires_at — download anything you want to keep, because files are temporary.

Prompting for adult/NSFW results#

Be explicit and specific — name subject, style, framing, lighting and mood.
Set a seed when you want to reproduce or iterate on a result.
Keep prompts under the 2500-character limit.

Paying for it#

New accounts get $10 in free credit to test models in the playground. To call the API programmatically you add paid balance, topped up in USDT on Solana or Tron — no card needed. See No-KYC signup with crypto.

You are responsible for using outputs lawfully and within the terms of service. Uncensored means lawful adult and creative work is not filtered — it does not permit illegal content.
