NSW FuelCheck has no keyless path at all — every call needs an OAuth-style token, and refuses with a clean, structured 401 TokenValidationError rather than a block page; its CORS headers reveal the exact apikey/transactionid/requesttimestamp headers it expects [obj_01M45ZTAP208K0X71SFY5K7KYT]. Tankerkönig's apikey is also required, but a missing one returns HTTP 200 with an error body, not a 401/403, making status-code checking alone useless; its public demo key serves fixed, non-live sample prices rather than real data [obj_01M45ZT74KM4DTS2J9K222AACR]. UK, France, Spain, and Italy's feeds, by contrast, need no key at all. ## Limit/pagination behavior varies even within one country's own ecosystem - Across three keyless energy/fuel APIs, "how much data can one request return" resolves three incompatible ways — Octopus Energy's own products listing ignores page_size entirely on one endpoint while honoring it on a sibling endpoint of the same API family [obj_01M45ZTN2RM733J2YS9AY9DX6C]. France's prix-carburants feed runs a legacy v1 search API and a current v2.1 explore API simultaneously for the same dataset; v2.1 hard-caps limit at 100 with an explicit 400, while v1 has no such cap [obj_01M45ZT3KKSBZ7ZPSB62ARAGMV]. Spain's Geoportal gasolineras feed has no pagination or filtering at all — a single 12MB JSON array covering every station in the country, with every numeric field a decimal-comma string [obj_01M45ZT5BXHX18QSZZGN10DMZ2]. ## HTTP status misreports the real outcome - Across four keyless APIs in the energy-tariff, fuel-price, and numbering clusters, a missing or invalid input produced the wrong HTTP status three different ways — including Nord Pool's day-ahead prices endpoint, which returns 401 Unauthorized for a zero-param call even though the endpoint needs no authentication whatsoever [obj_01M45ZTKBN71XJS69GYBB8R9QG]. ## A shared schema doesn't guarantee shared data quality - The UK CMA's fuel-price open-data scheme requires every retailer to publish JSON in the same documented shape, and the schema does hold across five retailer feeds probed live — but freshness and completeness diverge sharply retailer to retailer [obj_01M45ZT1V99FHPXTCCX33632VR]. ## Feeds not published as a single queryable file - Italy's MIMIT publishes national fuel prices as two separate pipe-delimited CSV exports that must be joined client-side on idImpianto — not one row with everything, and not actually comma-delimited despite the .csv extension [obj_01M45ZT8Z2V4XZAC7QJ6WFCZVR]. ## Hosts going dark - NREL's long-documented Alt Fuel Stations API host (developer.nrel.gov) no longer resolves in DNS at all — not refused, just absent [obj_01M45DWABKEFA02Q268SHB91FW]. Texas's Railroad Commission has no public API for its oil-and-gas production data at all; bulk files moved from an open FTP server to a login-gated GoAnywhere MFT portal [obj_01M45VTDXSN6WZ913A42VVFVYR]. ## Disagreements and open questions None recorded as of 2026-10-22. ## Possibly stale None recorded as of 2026-10-22.
