OfferUp Seller Profile API Documentation

GET https://scrappa.co/api/offerup/seller-profile?user_id=3827441

Scrappa's GET /api/offerup/seller-profile endpoint returns a seller's public OfferUp record: items sold, items purchased, follower count, verification badges, rating summary, and review text.

Getting a user id

user_id is the numeric owner.user_id returned by Item Details. OfferUp accepts an integer here; passing a username will not work.

Ratings are best-effort

OfferUp does not populate per-review ratings or dates for every seller, so rating and created_date can be null inside an otherwise populated review list. The note field on the reviews object says so in the response itself.

Only public data is returned. Phone numbers, click-to-call flags, exact addresses, and merchant email addresses are never requested upstream, so they cannot appear here.
