Questions about fanserv.com
How do I add fanserv.com to app-ads.txt?
Add one line for each account fanserv.com gives you: "fanserv.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 fanserv.com. The account ID must be the seller_id fanserv.com lists for you in its sellers.json; fanserv.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 fanserv.com publish a sellers.json?
Yes. Its file at https://fanserv.com/sellers.json listed 72 sellers when we last read it on 9 October 2026: 70 publishers, 0 intermediaries and 2 listed as both; 0% are confidential.
How many apps declare fanserv.com in app-ads.txt?
180 apps in Stoqlab's data (delisted apps included) declare fanserv.com: 177 with at least one DIRECT line and 13 with at least one RESELLER line, across 64 app-ads.txt files. Counts are recomputed daily.
Why do fanserv.com lines fail verification?
Of 259 lines naming fanserv.com, 7 contradict its sellers.json. The most common case is "RESELLER but publisher" (7 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask fanserv.com 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.
