Trade fair data, as a feed

1165 fairs worldwide — deduplicated across official venue sites, global aggregators and Chinese-language sources, geocoded, trust-scored and refreshed every day.

The directory is free and always will be. What you subscribe to is the part a crawler cannot reproduce: what changed — a fair added, a date moved, a venue switched, an event cancelled.

Why this exists

Planning a fair calendar today means opening six sites and diffing them by hand — and the answer to "did the dates move?" lives in nobody's API. We already crawl, deduplicate and verify this data every day; the change feed is that work, delivered.
