✨ 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 (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
• Model aliases: one model can expose multiple public ids — API calls with any alias resolve to it
• De-AI fingerprint (optional): one-click toggle on the playground — generated images get anti-AI-detection post-processing (subtle detail jitter + metadata stripping), charged as a per-tier surcharge (defaults 1K+1 / 2K+2 / 4K+3 credits, admin-configurable, can be disabled globally); processed works carry a "de-AI" badge across the playground, gallery, logs and admin image manager

🔌 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; de-AI fingerprint adds a per-tier surcharge
• 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)
• Gallery multi-select batch ops: select page / bulk delete (videos take their frame stills along) / bulk download (multiple files auto-packed into a zip, fetched concurrently)
• Lightbox preview with built-in copy original / download / close buttons; one-click copy of the original image from cards
• 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 + aliases) · 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 / banned-word hits) · CDK · image management (multi-select bulk delete / zip download) · showcase · announcements · site config (incl. epay, de-AI fingerprint toggle & surcharge pricing)
• Banned words: add / remove words in the console (paginated + multi-select bulk delete); prompts containing a banned word are rejected outright (playground + API, case-insensitive), with per-word / per-user hit counters

🧰 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).

🔌 OpenAI-Compatible API

# 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:

# 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):

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; }
}
