Questions about SpotX
How do I add SpotX to app-ads.txt?
Add one line for each account SpotX gives you: "spotx.tv, YOUR_ACCOUNT_ID, DIRECT, 7842df1d2fe2db34". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through spotx.tv. The account ID must be the seller_id SpotX lists for you in its sellers.json; SpotX 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 SpotX publish a sellers.json?
We could not reach it (last attempt 8 October 2026). Lines naming spotx.tv stay unchecked until it answers again.
How many apps declare SpotX in app-ads.txt?
118,464 apps in Stoqlab's data (delisted apps included) declare spotx.tv: 7,922 with at least one DIRECT line and 117,906 with at least one RESELLER line, across 16,088 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for SpotX?
97% of the app-ads.txt lines naming spotx.tv carry "7842df1d2fe2db34" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
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.
