Who You Are Writing To
x402 List is operated by Cosimo Miccolis, an individual based in Italy. The directory is run by one person, which is why there is one address and no support desk.
One Address
Everything reaches the same inbox: info@x402-list.com. It is read by a person, not a ticketing system. There is no phone number and no chat widget, and we would rather have one channel that is actually answered than several that are not.
Getting a Listing Removed
Write from any address and name the service. Roughly half the directory was discovered from public x402 indexes rather than submitted by the operator, and every one of those entries says so on its own page, with a removal link next to it. You do not need to prove ownership to ask for removal, and we do not ask why.
If instead you want to keep the listing and fix what it says, you can edit the descriptive
fields yourself from /services/<slug>/update. Measured data such as
uptime, pricing, and on-chain volume stays read-only for everyone, including us: correcting
it means correcting what we measure, so tell us what looks wrong and we will look at the
measurement.
Privacy Requests
To ask for a copy of your data, correct it, delete it, or object to how it is used, write to the same address. We reply within one month, which is the deadline the law sets. What we hold, why, and for how long is set out in the privacy policy.
Security Reports
Same address, and it is also published in /.well-known/security.txt per RFC 9116. There is no bug bounty: this is a small independently operated directory. Report it anyway, and please give us a reasonable window before publishing.
Press and Data Reuse
The directory data is published under CC BY 4.0, so you can reuse it with attribution without asking us first: see the API docs for the machine-readable feeds and the exact attribution string. Write only if you need something the public endpoints do not already give you.
