API Keys

The API Keys page is where you create keys for HPP Router — HPP's AI model gateway — and browse the models you can call from your own code.

Create an API key​

  1. Open API Keys from the left sidebar.
  2. Select Create Key and give it a name.
  3. Copy the key and store it somewhere safe.

You can create several keys and revoke any of them at any time. Treat a key like a password — keep it server-side and never commit it to source control.

Note: API usage and the Playground draw from the same Credits. Top up on the Wallets page.

Browse available models​

The page lists every model HPP Router can route to, in two tables:

  • Text models — chat and code models from providers such as Anthropic (Claude), OpenAI (GPT), and Moonshot AI (Kimi), plus free open models. Each shows its input and output price per million tokens (MTok).
  • Image models — image-generation models, priced the same per-use way.

The list and prices shown in the Hub are always current, so check there for the definitive catalog.

Make a request​

Your key works with any OpenAI-compatible client. Point the base URL at HPP Router and send the key as a Bearer token:

curl https://router.hpp.io/llm/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "hpprouter/auto",
    "max_tokens": 1024,
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

The virtual hpprouter/auto model lets HPP Router pick a cost-appropriate model for each request. To call a specific model, use its full id (for example anthropic/claude-sonnet-4-6).
