## ✨ Overview

**image2api** wraps the image / video capabilities of Adobe Firefly, OpenAI, Runway, Grok, 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 · 🤖 7 platforms, 10+ models · 🔁 auto failover / token keep-alive · 💳 credits + agent pricing · 🎨 generation frontend + admin console · 🐳 one-command deploy (bring your own TLS proxy)

## 🚀 Features

#### 🎨 Generation
- Images + videos in one place, with **image-to-image / reference frames** (first frame, last frame, style reference)
- Multiple resolutions (images 1K / 2K / 4K · videos 720p / 1080p), aspect ratios and video durations — configured and priced per model
- 7 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` drives **both aspect ratio + resolution tier** (images by long edge → 1K/2K/4K, videos by short edge → 720p/1080p) — just swap `base_url` + `api_key` into an existing OpenAI SDK
- Image results returned **inline as base64** — nothing stored server-side, privacy-friendly; the in-app **/docs** ships a size ↔ tier reference table

#### 🔁 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

#### 🔐 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
- **Online top-up (易支付 / epay)**: WeChat / Alipay QR, preset + custom amounts, unpaid orders auto-cancel after 30 min, MD5-verified idempotent callback auto-credits; cumulative top-up tracked
- **CDK redeem codes** · **referral rewards** · email sign-up / verification code / password reset
- **Concurrency groups**: cap a user's simultaneous generations (playground + API key combined, `0` = unlimited), self-healing Redis counters, new users auto-join the default group
- Three roles: regular user / agent / admin (single)

#### 🖥️ User Frontend (Vue 3)
- Playground · creations gallery · generation logs (with failure reasons / source tags)
- **Top-up · Orders** (recharge history / resume unpaid) · API docs · API key management · referral · about, light / dark theme
- **In-app announcements**: a Markdown notice pops up after login and re-shows whenever its content changes

#### 🛠️ Admin Console
- Overview dashboard (trends / DAU / top failures / top spenders)
- Model management (normal + agent price) · account management (bulk import / dedup / quota) · **concurrency groups** · **order management** (filter / search / paginate) · site-wide logs · user management (set as agent / assign concurrency group / view cumulative top-up) · CDK · showcase · **announcements** · site config (incl. epay)

**🧰 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 (TLS via your own reverse proxy).

## 🤖 Supported Models / Providers

| Provider | Models (examples) | Type |
|---|---|---|
| **Adobe Firefly** | firefly-image-5 · firefly-gpt-image-2 · flux-kontext-max · firefly-video · firefly-ray · gemini-veo31 | Image / Video |
| **OpenAI** | gpt-image-2 | Image |
| **Runway** | runway-gen4-turbo · nano-banana-2 (Nano Banana 2) | Video / Image |
| **Grok (grok.com)** | grok-video (imagine text/image-to-video) | Video |
| **Leonardo.ai** | seedream-4.5 | Image |
| **Krea.ai** | flux-klein-2 | 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 drives both aspect ratio + tier (long edge <1800→1K / <3500→2K / ≥3500→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": "2048x2048"
  }'

# 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

> Domain + HTTPS are handled by your own reverse proxy (this project issues no certificates).

**Docker (recommended)**: `docker compose up -d --build` brings up PostgreSQL + Redis + RustFS + backend + frontend (nginx serving **HTTP on container port 2000**); point your reverse proxy at `http://<host>:2000` (port via `WEB_PORT`; edit the values (passwords / keys / `CORS_ORIGINS`, and `COOKIE_SECURE=true` when your proxy serves HTTPS) directly in `docker-compose.yml`).

Or **build from source** — bring your own **PostgreSQL · Redis · RustFS (or any S3) · reverse proxy**:

```bash
# 1. Create an empty database (the backend auto-migrates on start)
createdb vivid_ai

# 2. Configure and build the backend from source
cat > backend/.env <<'EOF'
APP_ENV=production
HTTP_ADDR=127.0.0.1:6666
POSTGRES_DSN=host=127.0.0.1 user=postgres password=YOUR_PASSWORD dbname=vivid_ai port=5432 sslmode=disable TimeZone=Asia/Shanghai
REDIS_ADDR=127.0.0.1:6379
RUSTFS_ENDPOINT=http://127.0.0.1:9000
RUSTFS_BUCKET=vivid-ai
RUSTFS_ACCESS_KEY=YOUR_AK
RUSTFS_SECRET_KEY=YOUR_SK
CORS_ORIGINS=https://your-domain
COOKIE_SECURE=true
EOF
cd backend && go build -o bin/api ./cmd/api && ./bin/api   # listens on 127.0.0.1:6666

# 3. Build the frontend (output in frontend/dist)
cd frontend && npm install && npm run build
```

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

```nginx
server {
    listen 443 ssl;
    server_name your-domain;
    ssl_certificate     /path/fullchain.pem;
    ssl_certificate_key /path/privkey.pem;
    root /path/to/frontend/dist;
    index index.html;
    client_max_body_size 50m;
    proxy_read_timeout 600s;            # video generation can take a while

    location /assets/ { expires 1y; add_header Cache-Control "public, max-age=31536000, immutable"; }
    location / { try_files $uri $uri/ /index.html; add_header Cache-Control "no-cache"; }
    location ^~ /admin/api/ { proxy_pass http://127.0.0.1:6666; }
    location ^~ /images/    { proxy_pass http://127.0.0.1:6666; }
    location = /health      { proxy_pass http://127.0.0.1:6666; }
    location ^~ /v1/        { proxy_pass http://127.0.0.1:6666; add_header Cache-Control "no-store" always; }
}
```
