Common errors with anzu.io lines
-
Seller type BOTH
535 lines
The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
-
RESELLER but publisher
359 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask anzu.io why the account is listed as PUBLISHER.
-
Seller ID not found
258 lines
Ask anzu.io 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.
-
DIRECT but intermediary
1 line
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask anzu.io to list it as PUBLISHER.

Questions about anzu.io
How do I add anzu.io to app-ads.txt?
Add one line for each account anzu.io gives you: "anzu.io, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through anzu.io. The account ID must be the seller_id anzu.io lists for you in its sellers.json; anzu.io 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 anzu.io publish a sellers.json?
Yes. Its file at https://admins-api.anzu.io/sellers.json listed 1,196 sellers when we last read it on 9 October 2026: 1,137 publishers, 58 intermediaries and 1 listed as both; 0% are confidential.
How many apps declare anzu.io in app-ads.txt?
84,565 apps in Stoqlab's data (delisted apps included) declare anzu.io: 14,491 with at least one DIRECT line and 84,433 with at least one RESELLER line, across 10,625 app-ads.txt files. Counts are recomputed daily.
Why do anzu.io lines fail verification?
Of 53,379 lines naming anzu.io, 618 contradict its sellers.json. The most common case is "RESELLER but publisher" (359 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask anzu.io why the account is listed as PUBLISHER.
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.
