See who is authorized to sell a publisher's inventory, flag unauthorized resellers, and score supply chain health. All from public data.
We fetch the publisher's ads.txt file which lists every company authorized to sell their ad inventory, including seller IDs and relationship types.
For each ad system found, we fetch their sellers.json to verify seller IDs exist, check domain ownership, and identify undisclosed intermediaries.
We map every supply path and flag issues: unverified sellers, domain mismatches, missing transparency files, duplicate entries, and confidential sellers.
