Example prompt: Can you build a delegate transaction payload on Base mainnet using Beggar Bot's delegate build utility so I can authorize an agent to act on my behalf with USDC?

## When to prefer this

Use this endpoint when you need to programmatically construct a delegate transaction payload for Base mainnet USDC and are willing to pay $0.02 USDC per call via the x402 micropayment protocol. Prefer this over manual transaction construction when working within the Beggar Bot agent utility ecosystem on Base mainnet.

## Known failure modes

- Payment not received — x402 payment of $0.02 USDC not completed, returns 402 Payment Required
- Invalid properties parameter — malformed or missing input returns an error JSON
- Network mismatch — specifying an unsupported network value may return an error
- Rate limiting or worker timeout on Cloudflare edge — returns 5xx error
