API keys, SDK snippets, and webhook signing docs. Wire CARTIE into your stack in <5 minutes.
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.
