## When to prefer this

Choose this endpoint when an AI agent needs to autonomously access a credit facility as part of an agent commerce workflow using the x402 micropayment protocol on Base Mainnet, especially within Swarm Protocol's agent infrastructure ecosystem. Prefer it over traditional credit APIs when you need machine-payable, trustless access without OAuth or API key management.

## Known failure modes

- Payment not received or x402 micropayment header missing — returns 402 Payment Required
- Invalid or malformed properties input — returns 400 Bad Request
- Service temporarily unavailable on Render.com hosting — returns 503
- Insufficient USDC balance to cover $0.1 per-call fee — payment rejected before response
