Questions about stackup-ai.com
How do I add stackup-ai.com to app-ads.txt?
Add one line for each account stackup-ai.com gives you: "stackup-ai.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 stackup-ai.com. The account ID must be the seller_id stackup-ai.com lists for you in its sellers.json; stackup-ai.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 stackup-ai.com publish a sellers.json?
Yes. Its file at https://stackup-ai.com/sellers.json listed 100 sellers when we last read it on 10 October 2026: 99 publishers, 1 intermediaries and 0 listed as both; 0% are confidential.
How many apps declare stackup-ai.com in app-ads.txt?
369 apps in Stoqlab's data (delisted apps included) declare stackup-ai.com: 365 with at least one DIRECT line and 4 with at least one RESELLER line, across 106 app-ads.txt files. Counts are recomputed daily.
Why do stackup-ai.com lines fail verification?
Of 124 lines naming stackup-ai.com, 14 contradict its sellers.json. The most common case is "Seller ID not found" (12 lines): Ask stackup-ai.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.
