Quickstart

Create a key in API Keys. Copy it once. Add prepaid credits in Credits.

Set your key

export REDROUTER_API_KEY="YOUR_REDROUTER_API_KEY"

Send a request

curl -X POST 'https://redrouter.org/v1/chat/completions' \
  -H "Authorization: Bearer $REDROUTER_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
  "messages": [
    {
      "content": "Hello",
      "role": "user"
    }
  ],
  "model": "glm-5.3-flash-rr"
}'

import os, json
from urllib.request import Request, urlopen

body = json.loads(r'''{
  "messages": [
    {
      "content": "Hello",
      "role": "user"
    }
  ],
  "model": "glm-5.3-flash-rr"
}''')
request = Request(
    "https://redrouter.org/v1/chat/completions",
    method="POST",
    data=json.dumps(body).encode(),
    headers={
        "Authorization": "Bearer " + os.environ["REDROUTER_API_KEY"],
        "Content-Type": "application/json",
    },
)
with urlopen(request) as response:
    print(json.load(response))

const key = process.env.REDROUTER_API_KEY;
const response = await fetch("https://redrouter.org/v1/chat/completions", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${key}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "messages": [
      {
        "content": "Hello",
        "role": "user"
      }
    ],
    "model": "glm-5.3-flash-rr"
  }),
});
if (!response.ok) throw new Error(await response.text());
console.log(await response.json());

Set base_url

For an OpenAI-compatible SDK, set base_url to https://redrouter.org/v1. Set api_key to your RedRouter key.

from openai import OpenAI
import os

client = OpenAI(base_url="https://redrouter.org/v1", api_key=os.environ["REDROUTER_API_KEY"])
response = client.chat.completions.create(
    model="glm-5.3-flash-rr",
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)

Clients that add an /api prefix may also use /api/v1 for the existing API operations, with the same authentication, limits, and streaming behavior. The canonical base URL remains https://redrouter.org/v1.
