How it works

Two ways to use Costillery.

Pick the mode that fits your stack. Both pay per call — no monthly commitment.

API Key Mode

Traditional. Predictable.

Generate an API key from the dashboard. Pass it as a Bearer token. Works with any HTTP client, any language, any stack.

✓ Dashboard API key management
✓ Works with curl, fetch, any HTTP client
✓ Per-call billing — $0.005 each
✓ Spend limits and controls

POST api.chancelove.ai/cron/schedule

Authorization: Bearer YOUR_API_KEY

MPP Mode x402 native

No keys. Pay per call.

Your AI agent sends USDC directly to the service via x402 (EIP-3009). No accounts, no API keys, no signup. Like a vending machine for AI services.

✓ No account required
✓ Agent-native payment headers
✓ USDC on Base — $0.005 per call
✓ Built for AI-to-AI workflows
