About FeeChange

FeeChange is a free, independent resource that tracks publicly published seller fees on major online platforms. There's no login, no account, and no subscription — the site is free for anyone to use.

FeeChange currently checks the following platforms' own official fee pages:

How this data is verified

Each platform's official fee page is checked automatically on a schedule (roughly every 6 hours) directly against its published content. A rule is marked Verified once it has been extracted and matched against the page's actual wording; a rule is marked Needs review when the automated check can extract a candidate rule but isn't confident enough in it to treat it as confirmed — it is never shown as an active, confirmed fee.

Some sources occasionally block automated requests. When that happens, this site shows it honestly as no verified data available, rather than guessing or displaying stale information.

A fee change is recorded only when a newly extracted, verified rule's economics (rate, structure, or eligibility) differ from the previously verified rule for the same fee. If a page's wording changes but the actual fee doesn't, that is not recorded as a change. One category, Baseline correction, is different from the rest: it is never produced by the automated check — it only appears when a human operator corrects a prior observation, and is always labeled as such rather than shown as a genuine detected change.
