Archive.org vs Urban Observatory
The Internet Archive's Advanced Search and Metadata APIs let you query and pull structured records for its 99+ million digitized books, web captures, audio, video, and software items. Reads are keyless for both the search endpoint (archive.org/advancedsearch.php) and per-item metadata (archive.org/metadata/{identifier}), returning JSON, XML, or CSV depending on the requested output format.
Urban Observatory, run by Newcastle University, streams one of the UK's largest real-time urban sensor networks, covering air quality, traffic, flooding, and weather, from thousands of fixed and mobile sensors across Newcastle and partner cities. Its v2 API is fully keyless and exposes sensor locations and readings as JSON, CSV, or Shapefile, with bounding-box filtering for GIS tools. It's an academic, publicly funded service with no commercial tiers.
