Quick start

Three steps. Two minutes.

1

Create an API key

POST to /api/keys with a name. You'll get an isk_ key back once.

curl -X POST https://infersave.polsia.app/api/keys \
  -H "Content-Type: application/json" \
  -d '{"name":"my-app"}'
2

Point your SDK at InferSave

Change the base URL. Keep everything else the same.

// Python
client = OpenAI(
  base_url="https://infersave.polsia.app/v1",
  api_key="isk_your_key_here"
)

// Node.js
const client = new OpenAI({
  baseURL: "https://infersave.polsia.app/v1",
  apiKey: "isk_your_key_here"
})
3

Make requests as usual

Use gpt-4o, gpt-4o-mini, claude-sonnet, or claude-haiku. Anthropic models are automatically translated to the Messages API format.

Know your AI costs.
Down to the token.

No dashboards to configure. No SDKs to install. Just change your base URL and every request is tracked.
