Getting started

Quickstart

Make your first request in under a minute.

Create an account — you get $5 in free credits, no card required.
In the dashboard, open API Keys and create a key. Copy it immediately — it's shown only once.
Make your first request:

bash

curl https://api.routerplex.com/v1/chat/completions \
  -H "Authorization: Bearer $ROUTERPLEX_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Swap "gpt-5.5" for any ID in the model catalog — same endpoint, same request shape.

With the OpenAI SDK #

python

from openai import OpenAI
 
client = OpenAI(
    base_url="https://api.routerplex.com/v1",
    api_key="sk-...",  # your RouterPlex key
)
 
response = client.chat.completions.create(
    model="claude-opus-4-8",
    messages=[{"role": "user", "content": "Explain HTTP in one line"}],
)
print(response.choices[0].message.content)

No code at all? Try models in the playground first.
