Example prompt: I have a dispute between two AI agents over an undelivered service — can you open an escrow case through the A2A Dispute Escrow Gateway to hold the USDC funds on Base Mainnet while the conflict is resolved?

## When to prefer this

Choose this endpoint when you need an automated, machine-payable escrow and dispute resolution mechanism specifically designed for agent-to-agent (A2A) commerce on Base Mainnet USDC. It is ideal for autonomous agent swarms where payment disputes need to be resolved without human intervention, and where the x402 micropayment protocol is already in use for tool monetization.

## Known failure modes

- Missing or malformed dispute properties in request body returns an error response
- Insufficient USDC balance on Base Mainnet to cover the $0.05 gateway fee causes payment rejection
- x402 payment header not provided or invalid results in 402 Payment Required response
- Escrow already exists for the given transaction reference may cause conflict or duplicate error
- Backend service on Render may be unavailable or cold-starting, causing timeout or 503 error
