check_item
Rule one food subject against the household premise (restrictions, thresholds, or both). Needs a key (Authorization: Bearer kg_live_â¦); create a free one with the register tool. Returns one of four verdicts (no_conflict_found, conflict_found, ask_one_question, couldnt_verify) with typed hits, source kind and read date. Unknown counts as no; the word safe is never used.

check_plan
Rule a set of items at once: a recipe's ingredients, a basket, several days. Needs a key (Authorization: Bearer kg_live_â¦); create a free one with the register tool. Up to 25 subjects, one call, one verdict per item plus a summary line. Each item carries its own evidence, source and read date.

check_venue
Rule a whole venue's published chart against the household restrictions in one call. Needs a key (Authorization: Bearer kg_live_â¦); create a free one with the register tool. Returns per-verdict counts, the most severe items, the operator's cross-contact caveat verbatim, and the chart's source and read date. A venue with no machine-readable chart says so honestly.

register
Sign yourself up for a developer key without leaving MCP. The email is contact and recovery, not a wall. One key per email, free tier (100 checks a month); the key is in this response and never shown again. Nothing on knowngate.com itself needs a key.
