Can I use this data in my product?
Yes — that's what it's for. Every venue Yumi serves is cross-checked across multiple sources and passes an exposure bar before we expose it, and we take responsibility for the data rights through a clear license. You get verified data to build on — without the terms-of-service and copyright risk that comes with scraping someone else's map into a commercial product. Free (Open Season) covers individuals querying in real time from their own AI tools; embedding, storing, or redistributing the data inside a product is commercial use and needs a separate data license.
Where does the data come from?
The backbone of the data comes from government open data (official business-permit records). It's public, freely usable data, not a copy of anyone's map. To confirm a venue actually exists and is open, we check platforms like Naver, Kakao and Google for one thing only: whether it's really there. Anything else that rides along, reviews, photos, blurbs, is discarded on the spot rather than stored, and our operational data keeps only the derived signals our own algorithm builds (scores, attributes). On top of that we add owner-verified details (the Yumi Partners app) and info from food influencers who've partnered and opted in. That's why every venue ships with when we last checked and how confident we are.
How often is it refreshed?
We re-check every venue on a 7-day cycle. If a place closed or its details changed, it's reflected on the next pass. The whole point is to stop an AI from confidently recommending a shop that closed last month.
How is this different from Google or Naver maps APIs?
Maps APIs give you the basics — name, coordinates, rating. What they can't easily do is intersect conditions like 'private room + parking + free corkage,' or narrow by 40-plus F&B-specific attributes like pet-friendly, power outlets, or atmosphere. Yumi is built for food & drink: it returns these attributes as structured JSON and hands them straight to AI agents over MCP.
Where do you have coverage?
Right now Seoul and Jeju are active — 140,000-plus restaurants and cafes — and we're opening cities one at a time. If you need a specific area or category soon, tell sales and we'll weigh it into the queue.
Is it accurate? How do you back that up?
Instead of just claiming it, we hand you the evidence: whether a venue was cross-confirmed across sources, the last-checked date, and a confidence value — so your AI can tell 'confirmed' apart from 'unknown.' We don't invent missing details; we store only positively confirmed signals.
Do you support both MCP and the REST API? Is it hard to wire up?
Both. AI clients like ChatGPT, Claude, and Cursor connect over MCP in a few lines; if you're writing your own backend, call the REST API. Issue a key and wire it in right away — no complicated setup; the developer guide walks you through it.
How much does it cost?
During Open Season, low-volume real-time lookups by an individual from their own AI tools are free. Embedding the data in a product or using it at scale is commercial use, offered via usage-based paid plans and data licensing. The full terms are on the pricing page.
Can I store or redistribute the data I receive?
Storing or copying responses in bulk beyond what's needed to answer a live query — or reselling, redistributing, or training AI models on them — is outside free use. If you need a dataset, we provide it properly through Bulk Export and data licensing; just contact sales.
