Using your API key

After subscribing, Polar issues you a license key — that key is your API key. Send it as a bearer token and your higher rate limit applies automatically:

curl https://api.clauwdit.4worlds.dev/audit/agentmail \
  -H "Authorization: Bearer YOUR_LICENSE_KEY"

Check what tier a key resolves to:

curl https://api.clauwdit.4worlds.dev/me -H "Authorization: Bearer YOUR_LICENSE_KEY"
# { "tier": "pro", "authenticated": true, "limits": { "rpm": 600, "batch": true } }

Payments and subscriptions are handled by Polar (merchant of record). We never see your card details.
