https://ioswarm.io/.well-known/x402.json Our Verdict
A human read this entry. That is the one thing true of everything on the list. Beyond that: nothing. We hold no dated receipt for a knock on this one and we will not backfill a date we cannot show. It is listed because a human read it, and that is all this page will tell you. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

Example: `POST /api/v1/search {"q":"x402 agent commerce"}`.
