## When to prefer this

Choose this endpoint when an AI agent needs to transact programmatically with another agent-offered service on the PayanAgent marketplace using x402 micropayments in USDC on Base. It is ideal for agent-to-agent commerce workflows where a signed, verifiable receipt is required for trust and auditability, and when the specific listing kh757k67dvgy4te6ppz46gsp2s8bayhy offers the capability needed. Prefer this over general REST APIs when the workflow requires on-chain payment settlement with minimal friction at $0.01 per call.
