One image generation API for every model

The same gateway key that reaches GPT, Claude, and Gemini for chat also generates images. Router One puts text-to-image models from multiple families — gpt-image-2, Gemini 3 Pro Image, Gemini 3.1 Flash Image, Doubao Seedream, Grok Imagine — behind one OpenAI-compatible endpoint at https://api.router.one/v1, with a flat per-image unit price and a cost trace for every request.

Text-to-image models in the catalog

The lineup follows the live catalog — each model's current per-image unit price is on the models page under the image category, and every detail page lists its supported endpoints with example calls.

Flat per-image pricing with a paper trail

Media models are unit-priced, so an image job costs one flat USD amount — and the gateway's observability applies to every generation.

• One flat unit price per generated image, shown live in the catalog — no token accounting on media output.
• Every request lands in Dashboard → Logs with model, unit cost, latency, and status — the same trace chat calls get.
• Per-key budgets and spend caps apply, so a production image key is capped independently of your chat traffic.

Call it like the OpenAI Images API

POST /v1/images/generations with a model ID and a prompt — the request shape follows the OpenAI Images API, so existing OpenAI SDK image code works after changing the base URL and key. Copy a model ID from the catalog. Image-to-image edits go to POST /v1/images/edits instead: multipart/form-data, with the reference image uploaded as the image field.

# Text-to-image via the OpenAI-compatible endpoint
curl -X POST https://api.router.one/v1/images/generations \
  -H "Authorization: Bearer sk-your-router-one-key" \
  -H "Content-Type: application/json" \
  -d '{"model": "<image-model-id>",
       "prompt": "An orange kitten wearing an astronaut helmet"}'

Top up with a card, Alipay, or stablecoins

Wallet balance is metered pay-as-you-go: top up with a card or Alipay through one hosted checkout, or with USDT/USDC on six chains — no US credit card required.

Video generation on the same key

The catalog also lists video generation models — Vidu Q3 Turbo, PixVerse, MiniMax Hailuo 2.3, and Wan 2.6 (image-to-video) — served at POST /v1/videos/generations with per-clip unit pricing. Image and video share the same key, wallet, and cost traces.

No low fixed cap for normal paid usage. Abuse prevention, per-account protection limits, and upstream constraints may still apply; if a request returns 429, check Dashboard -> Logs or contact support to raise limits.
