Questions about xtrmqb.com

How do I add xtrmqb.com to app-ads.txt?

Add one line for each account xtrmqb.com gives you: "xtrmqb.com, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through xtrmqb.com. The account ID must be the seller_id xtrmqb.com lists for you in its sellers.json; xtrmqb.com will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.

Does xtrmqb.com publish a sellers.json?

Yes. Its file at https://ads-rtb.ortb.tech/sellers.json listed 27 sellers when we last read it on 10 October 2026: 5 publishers, 21 intermediaries and 1 listed as both; 44% are confidential.

How many apps declare xtrmqb.com in app-ads.txt?

1,792 apps in Stoqlab's data (delisted apps included) declare xtrmqb.com: 33 with at least one DIRECT line and 1,759 with at least one RESELLER line, across 92 app-ads.txt files. Counts are recomputed daily.

Why do xtrmqb.com lines fail verification?

Of 105 lines naming xtrmqb.com, 105 contradict its sellers.json. The most common case is "Seller ID not found" (105 lines): Ask xtrmqb.com for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.

What is the difference between DIRECT and RESELLER?

DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
