Questions about mlion.io

How do I add mlion.io to app-ads.txt?

Add one line for each account mlion.io gives you: "mlion.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 mlion.io. The account ID must be the seller_id mlion.io lists for you in its sellers.json; mlion.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 mlion.io publish a sellers.json?

Yes. Its file at https://www.mlion.io/sellers.json listed 33 sellers when we last read it on 9 October 2026: 12 publishers, 21 intermediaries and 0 listed as both; 0% are confidential.

How many apps declare mlion.io in app-ads.txt?

41,790 apps in Stoqlab's data (delisted apps included) declare mlion.io: 14,517 with at least one DIRECT line and 41,790 with at least one RESELLER line, across 4,152 app-ads.txt files. Counts are recomputed daily.

Why do mlion.io lines fail verification?

Of 8,043 lines naming mlion.io, 751 contradict its sellers.json. The most common case is "RESELLER but publisher" (725 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask mlion.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.
