Beginner guide

Use OpenAI or Anthropic with OpenClaw and Hermex.

You do not need to understand the full API to get started. Create an account, top up your balance, generate an API key, then copy three values into your tool.

The path

Four steps before your first message.

01Create an account
The dashboard opens before you pay, so you can explore it before topping up.
02Top up your balance
The minimum is USD 10. The calculator shows credits and bonuses before you pay.
03Create an API key
Your full key is shown once. Store it in your password manager or secret manager.
04Paste the key into your tool
OpenClaw and Hermex use the same API key and base URL. Start with Terra, then choose an OpenAI or Anthropic model when needed.

OpenClaw / Hermex

Both tools use the same connection details.

Field names can vary by interface, but the setup is the same: base URL, API key, model, and route.

OpenClaw

Choose an OpenAI-compatible provider, then replace the base URL with llmhub.ch.

Base URL: https://llmhub.ch
API key: aph_live_...
Recommended model: gpt-5.6-terra
Recommended route: /v1/responses

Hermex

Use the custom API profile and enter the Responses route if the tool offers it.

Base URL: https://llmhub.ch
API key: aph_live_...
Recommended model: gpt-5.6-terra
Recommended route: /v1/responses

First test

If you get a response, your connection is ready.

Start with a short prompt. The dashboard will then show the call cost and your remaining balance.

✓Your balance must be positive before your first call.
✓Use an Authorization header with Bearer followed by your API key.
✓Start with gpt-5.6-terra, then freely choose any active OpenAI or Anthropic slug.
✓If a tool asks for a full URL, use the complete route.

Minimal example

curl https://llmhub.ch/v1/responses \
  -H "Authorization: Bearer aph_live_..." \
  -H "Content-Type: application/json" \
  --data-binary @- <<'JSON'
{
  "model": "gpt-5.6-terra",
  "input": "Say hello in English."
}
JSON
