xARP enables a commercially viable way to host and maintain x402 endpoints on a decentralised register. It is perfect for AI Agents to search and interact with x402 autonomously.
This submission comes with a developer friendly CLI to add endpoints to the registry (for a fee) and update their endpoint in case the price or req / res body has changed.
Also, a custom action provider for CDP Agents was created so they can autonomously search for endpoints, then pay for them.
CDP v2 SDK was not working with x402 action provider. I then pivoted to use v1 which worked. besides that, no issues - github examples were very useful.
Also, I originally tried to have an x402 endpoint which extracts tables from PDFs, and uses form data + file to post to endpoint. However, it was non-trivial to make this easily usable hence the pivot to focus on registry and basic endpoints.
