# Adagio bot

Adagio platform complies with the [Supply Chain Validation](https://iabtechlab.com/software/supply-chain-validation/) from IAB.

In order to do so, we need to be able to fetch the `ads.txt` and/or `sellers.json` files hosted on your domain.

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 an `User-Agent` header containing `Adagiobot`
* Allowing the CIDR range listed in [this file](https://assets.adagio.io/adagiobot-ipv4.txt)
