Agent Payment Infrastructure: x402 and MPP

Agents discover a service, call it, pay, and continue SameDayDesk machine services settle exact Base USDC through x402 or native MPP. No API key, subscription, or account is required. Discovery is not authorization, settlement, demand, or revenue. Live catalogs are authoritative; this page does not freeze a tool count. Practical jobs live on /for-agents: paid bounded POST /extract/batch observations, free offline comparison and explicit buyer-record mapping, opt-in reuse of an already produced result, and one-shot recurring page or record recipes with immutable priors. Purchasing never requires publishing. Other named calls remain on the live inventory.
