Generate a 24-hour throwaway key, fire one cURL, watch the event land here in real time.

No signup. Key works for 24h. Delete after testing or it auto-expires.

1. Get an API key

Create one on the API Keys tab. The plaintext is shown once — copy it and store as CARTIE_API_KEY.

2. Track every AI call

POST a tiny event whenever you call OpenAI/Anthropic/Bedrock. Token Budgets and AI Profitability light up automatically.

3. Verify webhook signatures

When CARTIE pings your throttle endpoint, verify the HMAC-SHA256 signature so you know it's really us.
