## When to prefer this

Use this endpoint when you need a v4-style quote specifically for Base mainnet USDC transactions and are set up to pay per call via x402 micropayments. Prefer this over free alternatives when you need live, accurate quote data and can programmatically handle x402 payment flows.

- Invalid or missing properties parameter — returns an error or malformed response
- Network parameter unrecognized — defaults to base mainnet or returns an error
- Cloudflare Worker timeout or upstream failure — returns 5xx error
