How to use the orosy Buyer API. The endpoint list lives in the API reference.
Overview — 200,000+ products from multiple Japanese suppliers through one API — authentication, a typical flow, and the design promises (price-change guard / reservation-based billing / idempotency).
Your first order in 15 minutes — Search, cart, test order, and confirmed reservation — the whole loop in 15 minutes, with curl you can paste as-is.
Talk to your AI and source from Japan — Source from 200,000+ Japanese products through the AI you already use — search to test order in about 15 minutes, no code.
Order from an AI agent (MCP) — Connect an AI agent to the MCP endpoint and go from search to order in natural language — setup steps and the tool list.
Partial out-of-stock and billing — You are billed only for what is reserved. How the totals break down, and what happens when nothing is available.
