​
1. Get your API key

  1. Go to euron.one/euri and sign in (or create an account).
  2. Navigate to Billing & API Keys.
  3. Click Create API Key and copy the key.
Keep your API key secret. Do not expose it in client-side code or public repositories.

​
2. Make your first request

curl -X POST https://api.euron.one/api/v1/euri/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_EURI_API_KEY" \
  -d '{
    "model": "gpt-4o-mini",
    "messages": [
      {"role": "user", "content": "Say hello in 3 languages."}
    ],
    "max_tokens": 150
  }'

from euriai import EuriaiClient

client = EuriaiClient(api_key="YOUR_EURI_API_KEY")

response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Say hello in 3 languages."}],
    max_tokens=150
)

print(response.choices[0].message.content)

import { EuriClient } from 'euri';

const client = new EuriClient({ apiKey: 'YOUR_EURI_API_KEY' });

const response = await client.chat.completions.create({
  model: 'gpt-4o-mini',
  messages: [{ role: 'user', content: 'Say hello in 3 languages.' }],
  max_tokens: 150,
});

console.log(response.choices[0].message.content);

​
3. Use with the OpenAI SDK

EURI is fully OpenAI-compatible. Just change the base URL: 
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EURI_API_KEY",
    base_url="https://api.euron.one/api/v1/euri"
)

response = client.chat.completions.create(
    model="gemini-2.5-flash",
    messages=[{"role": "user", "content": "Explain quantum computing simply."}]
)

print(response.choices[0].message.content)

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'YOUR_EURI_API_KEY',
  baseURL: 'https://api.euron.one/api/v1/euri',
});

const response = await client.chat.completions.create({
  model: 'gemini-2.5-flash',
  messages: [{ role: 'user', content: 'Explain quantum computing simply.' }],
});

console.log(response.choices[0].message.content);
