Billing reads the same table this page does, so the price you see is the price you are charged. Cache read/write apply when the upstream provider reports cached tokens.

How to call it

The OpenAI-compatible chat endpoint, POST https://jzstoken.com/api/v1/chat/completions. This is the format the client guides assume and the one our own catalog listings are checked against before they can be called at all.

curl https://jzstoken.com/api/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-YOUR_KEY_HERE" \
  -d '{
    "model": "grok-4.5",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Replace sk-YOUR_KEY_HERE with a key from your dashboard. Top-ups start at $1.50; see Quick Start for the full walkthrough and the Python SDK version.

Clients that require the Anthropic Messages format can use POST https://jzstoken.com/api/v1/messages instead — see the Claude Code and Cursor guides. Which of these two formats any individual model supports through our gateway has not been certified per model, so try the chat endpoint first.

Not listed here yet

We would rather leave these blank than fill them with a number nobody verified: maximum output tokens, per-model rate limits, and per-model certification for streaming, tool calling or structured output. None of that is returned by the upstream pricing API and we have not measured it. If you need a specific figure for capacity planning, ask us and we will measure it rather than estimate.
