All projects on Base matching “units”

Takes two documents, by URL, inline base64 or raw text, extracts the text of each and compares them. Paragraphs are the unit: the answer lists every block that was removed, added, or kept but reworded, and for reworded blocks it names the individual words that went and came, so a single changed number in a long clause is visible instead of the whole clause being flagged. Alongside the content diff

Catalog of the macro liquidity series x402 serves (Fed net liquidity, global central bank balance sheets), with unit, source and update frequency ($0.01).

Check any x402 paid endpoint before paying it: does it return a valid 402 challenge, which networks/tokens/prices it accepts (decoded to USD), whether amounts are valid atomic units, payTo sanity, testnet-only offers, missing Bazaar input schema, redirects and latency.
