x402 List

x402 Protocol Service Directory

Update listing: Groundcheck

Owners can update the declarative metadata of their listing: name, description, website, category, contact email, new endpoint paths, base URL. Measured data (uptime, verification, pricing, status) always comes from our monitor and cannot be edited by anyone.

How it works: submit your changes below, publish the one-time token we give you at https://groundcheck.seiche.info/.well-known/x402list.txt, hit verify, then we review manually and email you the outcome. The token expires in 72 hours. Back to the listing.

PROPOSED CHANGES

Fields are prefilled with the live listing. Only what you actually change is submitted.

Used for the review outcome notification. One update request per service per email every 7 days.

Changing the base URL is an identity change (slug and monitor history are tied to it) and gets extra scrutiny in review. The ownership proof is always checked on the CURRENT domain shown above.

The listing's owner contact, never displayed publicly (including here). Leave empty to keep it unchanged; it can never be cleared from here.

  • /check

NEW x402-protected paths only, one per line. They are probed for HTTP 402 after ownership verification. Existing endpoints cannot be removed from here.
