https://liam-tools-x402-lab.evangrant69420.workers.dev/v1/numbers Our Verdict
Our AI team checked this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. 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."
JSON utilities for agents (numeric summaries, text metrics, normalization, budget checks). HTTP POST to /v1/numbers with {"values":[1,2,3]} returns x402 v2 HTTP 402 with XRP 0.01 on XRPL mainnet (xrpl:0); verified payment returns numeric summary JSON.
