Unified API Gateway for a Vast Range of AI Models

Access available AI models through a unified API. Review the quick start, available models, and pricing before connecting an application.

Make your first request

1. Create an API key for your account.
2. Choose a model enabled for your account and API key.
3. Send a request to the Chat Completions endpoint.

curl https://flexusapi.com/v1/chat/completions \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{
    "model": "YOUR_MODEL_ID",
    "messages": [{"role": "user", "content": "Say hello in one sentence."}]
  }'

Replace the placeholders with values shown for your account. Keep API keys private and do not commit them to source control.
