Authentication

All Elfa APIs require authentication using an API key. This document explains how to authenticate with our REST API.

Obtaining an API Key​

Get your API key from the Elfa Developer Portal.

caution

Keep your API key secure! Do not share it publicly or commit it to version control systems.

API Key Permissions​

API keys can have different permission levels:

  • Read-only: Can only access GET endpoints
  • Standard: Can access all standard API endpoints
  • Premium: Can access all endpoints, including those with higher rate limits

Authenticating with the REST API​

For all REST API calls, include your API key in the request header:

x-elfa-api-key: your_api_key_here

Example API Request with Authentication​

cURL​

curl -X GET "https://api.elfa.ai/v2/aggregations/trending-tokens" \
     -H "x-elfa-api-key: your_api_key_here"

JavaScript (Fetch)​

// Example API call
const fetchTrendingTokens = async () => {
  const response = await fetch("https://api.elfa.ai/v2/aggregations/trending-tokens", {
    headers: {
      "x-elfa-api-key": "your_api_key_here",
    },
  });
  return await response.json();
};

Python (Requests)​

# Example Python API call
import requests

headers = {
    "x-elfa-api-key": "your_api_key_here"
}

response = requests.get("https://api.elfa.ai/v2/aggregations/trending-tokens", headers=headers)
data = response.json()

API Key Management​

Checking API Key Status​

You can check the status and usage of your API key using the /v2/key-status endpoint:

curl -X GET "https://api.elfa.ai/v2/key-status" \
     -H "x-elfa-api-key: your_api_key_here"

The response will include:

  • Current usage statistics
  • Rate limits
  • Permissions
  • Expiration date (if applicable)

Revoking an API Key​

If your API key is compromised, revoke it immediately from the Elfa Developer Portal and generate a new one.

Troubleshooting​

If you encounter authentication issues:

  1. 401 Unauthorized: Check that your API key is correct and hasn't expired
  2. 403 Forbidden: Your API key doesn't have permission for the requested resource
  3. 429 Too Many Requests: You've exceeded your rate limit
