API keys authenticate your requests to Fenra.

​
Creating a Key

  1. Go to app.fenra.io
  2. Navigate to Settings → API Keys
  3. Click Create New Key
  4. Give it a descriptive name
  5. Copy the key immediately. It is only shown once.

​
Using a Key

Include it in the X-Api-Key header: 
curl -X POST 'https://api.fenra.io/ingest/usage' \
  -H 'Content-Type: application/json' \
  -H 'X-Api-Key: YOUR_API_KEY' \
  -d '...'

​
Managing Keys

In Settings → API Keys you can:
  • Create new keys with descriptive names
  • Deactivate keys temporarily (returns 401 immediately)
  • Delete keys permanently

​
Troubleshooting

If you’re getting 401 Unauthorized:
  1. Check the key exists in your dashboard
  2. Check it’s active (not disabled)
  3. Verify the header name is X-Api-Key
  4. Check for typos or extra spaces
