Authentication

All API requests require authentication via a Bearer token in the Authorization header.

Getting Your API Key

  1. Sign up at EvoLink
  2. Navigate to your API Key Management Page
  3. Create a new key and copy it — store it securely

Base URL

https://api.evolink.ai

Using Your API Key

Include the API key in every request header:

Authorization: Bearer YOUR_API_KEY

cURL Example

curl -X POST https://api.evolink.ai/v1/videos/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "seedance-2.0", "prompt": "A cat playing piano"}'

Python Example

import requests

headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}

response = requests.post(
    "https://api.evolink.ai/v1/videos/generations",
    headers=headers,
    json={"model": "seedance-2.0", "prompt": "A sunset over the ocean"}
)

Node.js Example

const response = await fetch("https://api.evolink.ai/v1/videos/generations", {
    method: "POST",
    headers: {
        "Authorization": "Bearer YOUR_API_KEY",
        "Content-Type": "application/json"
    },
    body: JSON.stringify({
        model: "seedance-2.0",
        prompt: "A sunset over the ocean"
    })
});

Security Best Practices

  • Never expose your API key in client-side code or public repositories
  • Store keys in environment variables or a secrets manager
  • Rotate keys periodically from your API Key Management Page
  • Use separate keys for development and production
