Adagio bot - Crawler

If you have issue with Supply Chain Validation

Requirements

Adagio needs to be able to crawl your (app-)ads.txt and sellers.json to validate:

• whether Adagio is allowed to sell the inventory, and which of its demand partners also are allowed

• whether you have access to this inventory

Therefore, ensuring that Adagio's bot has access conditions the monetisation performance of your account.

Adagio platform complies with the Supply Chain Validation from IAB.

In some situations, your web server might not allow bots to connect and get the content from these files, you can whitelist our bot by:

• Allowing requests with a User-Agent header containing Adagiobot (our bot's complete User-Agent is: Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Adagiobot/1.0) Chrome/112.0.5615.137 Safari/537.36

• Allowing the CIDR range (IP adresses) listed in this file

The (app-)ads.txt and sellers.json file size is limited to 15MiB. If the crawled file exceeds this limit, it will be considered invalid.

Here's a documentation section you can drop straight in, written for non-technical readers:
