​
1. Create an account

Sign up at app.infery.ai/register. Free accounts get 50 trial credits immediately — enough to try chat, a few images and some voice.

​
2. Open the Playground

Once you’re in, the Playground is the first screen you see.
  • Type a prompt in the input at the bottom, pick a model (default: auto-routed) and press Enter.
  • Switch between Chat · Generate Image · Text to Speech · Speech to Text · Generate Video · Generate Music at the top.
  • Drop a PDF, image or audio file on the message box to attach it.
Your first chat becomes a Chat. Create a Project to group related chats and share settings. See Chats and Projects.

​
3. Create an API key

Go to Settings → API Keys and click Create key. Give it a name (“Production”, “Local dev”), copy the plaintext key — it’s only shown once. API keys look like: 
inf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Treat API keys as secrets. Never commit them to git. Revoke a key immediately if exposed — it takes ~5 seconds in the dashboard.

​
4. Make your first API call

Our gateway is OpenAI-compatible. Point the OpenAI SDK at https://api.infery.ai: 
curl https://api.infery.ai/v1/chat/completions \
  -H "Authorization: Bearer $INFERY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [{"role": "user", "content": "Say hello in Russian"}]
  }'
You’ll get back a standard OpenAI-format response. The cost in credits is returned as an extra header (x-credits-used) and inside the final SSE chunk when streaming.
