## ✨ Overview
|
||||
|
||||
**image2api** wraps the image / video capabilities of Adobe Firefly, OpenAI, Runway, Leonardo, Krea and Imagine into **a single OpenAI-compatible API**. Behind it, multi-account pools are scheduled automatically — out of quota → switch account, auth expired → refresh or kill, transient errors → retry, tokens proactively renewed before they expire — to deliver a stable service.
|
||||
|
||||
It's more than an API proxy: it ships with **credit billing, CDK top-ups, referral rewards, a user system, an admin console, and a modern generation frontend**, so a single command turns it into a fully operational AI generation site — the author's live instance **[Vivid AI · vividai.run](https://vividai.run)** (brand) is built on this project.
|
||||
|
||||
> 💡 Both frontend and backend are **fully open-source** (MIT) — Go + Vue 3, free to fork and self-host.
|
||||
|
||||
**At a glance** 🔌 OpenAI-compatible · 🤖 6 platforms, 10+ models · 🔁 auto failover / token keep-alive · 💳 credits + agent pricing · 🎨 generation frontend + admin console · 🐳 one-command deploy + auto HTTPS

## 🚀 Features

<tr>

<td width="50%" valign="top">
|
||||
|
||||
### 🎨 Generation
|
||||
- Images + videos in one place, with **image-to-image / reference frames** (first frame, last frame, style reference)
|
||||
- Multiple resolutions (1K / 2K / 4K), aspect ratios and video durations — configured and priced per model
|
||||
- 6 providers, 10+ models, **enable / disable / re-price from the admin console**, no code changes
|
||||
|
||||
### 🔌 OpenAI Compatible
|
||||
- Text-to-image `/v1/images/generations` · image-to-image `/v1/images/edits` (multipart ref upload) · video `/v1/videos` (Sora-style async: create → poll → `/content`) · `/v1/models`
|
||||
- **Strict OpenAI params**: `size` sets the aspect ratio, `quality` the resolution tier — just swap `base_url` + `api_key` into an existing OpenAI SDK
|
||||
- Image results returned **inline as base64** — nothing stored server-side, privacy-friendly
|
||||
|
||||
### 🔁 Account Pools + Smart Failover
|
||||
- Round-robin scheduling across the pool; one bad account doesn't break the whole
|
||||
- **Out of quota → switch** · **auth expired → refresh & retry / kill** · **transient → retry same account ×3** · **bad params → fail fast**
|
||||
- **Pre-deducted credits**: atomic debit before generation, auto-refunded on failure, no over-spend under concurrency
|
||||
|
||||
</td>
|
||||
<td width="50%" valign="top">
|
||||
|
||||
### 🔐 Automatic Token Keep-alive
|
||||
- Single-use rotating tokens (Krea / Imagine) are **renewed proactively 10 minutes before expiry**; new tokens persisted automatically
|
||||
- Adobe cookies exchanged for fresh tokens on a schedule; bare JWTs killed on expiry
|
||||
- Daily quota recovered at each provider's reset time, then re-probed for the real balance
|
||||
|
||||
### 💳 Billing & Operations
|
||||
- Credit-based (**pre-deduct + refund on failure**), priced per model / resolution / duration
|
||||
- **Agent pricing**: a user can be set as an "agent" role and models can carry agent prices; agent users (including their API key calls) are billed at the agent price, falling back to the normal price when unset
|
||||
- **CDK redeem codes** · **referral rewards** · email sign-up / verification code / password reset
|
||||
- Three roles: regular user / agent / admin (single)
|
||||
|
||||
### 🖥️ User Frontend (Vue 3)
|
||||
- Playground · creations gallery · generation logs (with failure reasons / source tags)
|
||||
- API docs · API key management · referral · about, light / dark theme
|
||||
|
||||
### 🛠️ Admin Console
|
||||
- Overview dashboard (trends / DAU / top failures / top spenders)
|
||||
- Model management (normal + agent price) · account management (bulk import / dedup / quota) · site-wide logs · user management (set as agent) · CDK · showcase · site config

**🧰 Engineering highlights**: tls-client (Chrome JA3/JA4 fingerprint) reliably passes Cloudflare · media stored in S3/RustFS, served through an authenticated proxy with retention cleanup · self-healing maintenance loop (quota recovery / credential refresh / orphan-job cleanup with refunds) · one-command Docker deploy with acme.sh auto HTTPS.

## 🤖 Supported Models / Providers
|
||||
|
||||
| Provider | Models (examples) | Type |
|
||||
|---|---|---|
|
||||
| **Adobe Firefly** | firefly-image-5 · firefly-gpt-image-2 · nano-banana-2 · flux-kontext-max · firefly-video · firefly-ray · gemini-veo31 | Image / Video |

|
||||
| **Imagine.art** | imagine-1.5 · imagine-1.5pro | Image |
|

> Models are enabled and priced dynamically from the admin console — add or remove anytime.
|
||||
|
||||
## 🔌 OpenAI-Compatible API
|
||||
|
||||
```bash
|
||||
# Text-to-image — pure OpenAI params: size→aspect ratio, quality→tier (low/medium/high→1K/2K/4K)
|
||||
curl https://your-domain/v1/images/generations \
|
||||
-H "Authorization: Bearer sk-xxxx" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-image-2",
|
||||
"prompt": "a cute cat on a desk, studio lighting",
|
||||
"size": "1024x1024",
|
||||
"quality": "high"
|
||||
}'
|
||||
|
||||
# Image-to-image — multipart reference upload (multiple via image[])
|
||||
curl https://your-domain/v1/images/edits \
|
||||
-H "Authorization: Bearer sk-xxxx" \
|
||||
-F model="seedream-4.5" -F prompt="make it cyberpunk" -F image=@input.png
|
||||
```
|
||||
|
||||
Images return OpenAI-style `{ "created": ..., "data": [{ "b64_json": "..." }] }` (raw base64, no `data:` prefix, nothing stored server-side). **Video** is async: `POST /v1/videos` → poll `GET /v1/videos/{id}` until `completed` → `GET /v1/videos/{id}/content` for the mp4. Full parameters are documented on the in-app **/docs** page.
|
||||
|
||||
## 🚀 Deployment
|
||||
|
||||
Both frontend and backend are open-source. Docker one-command is recommended; you can also build from source with **Go 1.26+**.
|
||||
|
||||
> Prerequisite: a domain A-record pointing to this host, with **ports 80 / 443 open to the internet** (required for Let's Encrypt verification).
|
||||
|
||||
### Option 1: Docker, one command (recommended)
|
||||
|
||||
Requires Docker + Docker Compose. A single command brings up Postgres + Redis + RustFS + backend + frontend, and **auto-issues / renews the HTTPS certificate** (built-in acme.sh).
|
||||
|
||||
```bash
|
||||
cp .env.docker.example .env # fill in DOMAIN / ACME_EMAIL / POSTGRES_PASSWORD / S3_SECRET_KEY
|
||||
sh install.sh # = docker compose up -d --build
|
||||
```
|
||||
|
||||
Open `https://<your-domain>/`; watch cert progress with `docker compose logs -f acme`. With `DOMAIN=localhost` a self-signed cert is used (local testing).
|
||||
|
||||
<details>
|
||||
<summary><b>Option 2: Manual install</b> — bring your own PostgreSQL / Redis / RustFS / Nginx (click to expand)</summary>
|
||||
|
||||
<br/>
|
||||
|
||||
Provide your own **PostgreSQL · Redis · RustFS (or any S3) · Nginx**, **Go 1.26+** for the backend and **Node 18+** for the frontend.
|
||||
|
||||
```bash
|
||||
# 1. Create an empty database (the backend auto-migrates on start)
|
||||
createdb vivid_ai
|
||||
|
||||
# 2. Configure and build the backend from source

|

Nginx reverse proxy (issue the certificate yourself with certbot / acme.sh):
