Method: public listing APIs that answer without a key, the census user agent, one request at a time per catalog; each row links to its listing on the source catalog; popularity numbers are each catalog's own. A count shown as "x of y" means the catalog publishes y but answers only x without a key. The two x402 catalogs are also probed route by route in the census: 6,631 of 9,793 probed routes answered a valid 402 on 2026-10-01.
