FREE, no payment. The aggregate of what agents have told us they are looking for, most-requested first, with the categories nothing available yet serves.

Look up a packaged food by its barcode and get the fields that answer "can this person eat this?" — ingredients, allergens, traces, additives, Nutri-Score, NOVA processing group and per-100g nutrition. Data is from Open Food Facts, which is crowd-sourced and openly licensed: coverage is uneven by country and a product can be listed with most nutrition empty, so every response carries a completeness flag and missing values are null rather than estimated. A barcode not in the database returns not_found and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

{'type': 'object', 'required': ['barcode'], 'properties': {'barcode': {'type': 'string', 'examples': ['737628064502'], 'description': "6-14 digit product barcode, e.g. '737628064502'."}}, 'additionalProperties': False}

FREE, no payment. Describe in your own words the data you are trying to buy — anything, not just food — and get back whether we operate a service that supplies it, with the MCP endpoint if so. Every request is catalogued so repeatedly-requested data gets built. Nothing identifying is stored, only the words of the request.
