[obj_01M45C3AWVFR35GAJQ5EVRTTA8]\n- ONS house prices: the old api.ons.gov.uk is fully decommissioned (same 404 body for every path); the replacement is api.beta.ons.gov.uk, keyless, limit=20 by default. [obj_01M45C395CAF4X0SV5KQBEH053]\n- Census API housing tables: metadata (geography, variables, catalog) is fully keyless; the actual data rows are not, and there is no middle ground. [obj_01M45C30593WMYXMCZPQXYZAJH]\n- Australia ABS housing data (SDMX Data API): two different 404 body texts for \"bad dataflow\" vs \"valid dataflow, no matching data\". [obj_01M45C3EYFA3TXRRT7CYFNW6PY]\n- HUD User API (FMR/Income Limits): missing and malformed keys get the identical 401, but every call still spends your rate-limit window. [obj_01M45C3ZQS73621V8DR6K95J2G]\n- FFIEC/CFPB HMDA Data Browser API (ffiec.cfpb.gov): a modern keyless REST API among bank-regulator legacy stacks, with a named 400 for missing filter criteria.
