SBA publishes PPP loans as 13 separate static CSV files with no server-side filter: one for loans over $150,000, and twelve files of roughly equal size for loans of $150,000 and under. Each run scans only the file(s) you pick here. 'All tiers' streams all 13 in sequence until maxItems is reached or every file is exhausted - nationwide coverage, but it reads up to ~5.2 GB (measured 2026-10-05) so give it a generous maxItems and expect it to take several minutes.
