Questions about copper6.com
How do I add copper6.com to app-ads.txt?
Add one line for each account copper6.com gives you: "copper6.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 copper6.com. The account ID must be the seller_id copper6.com lists for you in its sellers.json; copper6.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 copper6.com publish a sellers.json?
Yes. Its file at https://seller.copper6.com/sellers.json listed 715 sellers when we last read it on 9 October 2026: 415 publishers, 106 intermediaries and 194 listed as both; 0% are confidential.

Why do copper6.com lines fail verification?
Of 41,452 lines naming copper6.com, 564 contradict its sellers.json.

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.
