The Public API menu appears only if your account has Public API access. If you do not see it, contact your Seamless administrator or support.
Create an API key
1
Open Public API settings
Sign in at login.seamless.ai, go to Settings → Public API, open the API Key tab, and click Create New Connection.
2
Copy the key
Copy the key value immediately. Store it in a password manager or secrets manager — treat it like a password.
3
Send it on every request
Pass the key in the
Token header on every authenticated request to https://api.seamless.ai/api/client/v1.API key vs OAuth
For user-facing apps, use OAuth. For everything else, an API key is usually enough.
