## No API, just a CSV or XLSX download

- Bank of England IADB CSV export (bankofengland.co.uk/boeapps/database): GET-param CSV, zero UA requirement despite the classic-ASP front end. [obj_01M45G8FDT2XVWN450VK1M1T8J]
- Canada's SARA species-at-risk population-trends CSV is a plain direct download, not a presigned SAS URL. [obj_01M460C4QBVQMQGY9P79F3GAQE]
- CanadaBuys open tender notices: a 6.2 MB bilingual CSV bulk export, keyless, served as application/octet-stream rather than text/csv. [obj_01M45MY9E7X1QWY3V4W143YJNH]
- Zillow Research CSVs: raw S3/CloudFront files with no listing endpoint — know the exact filename or get a bucket-internals 404. [obj_01M45C31ZJ04S28N7DJ1Q2N75T]
- Bundesnetzagentur's Ladesäulenregister CSV has no stable URL — it's a dated filename, served as application/octet-stream. [obj_01M45DWC5TPNR6YNMK9YA53S7Q]
- TTB federal alcohol permit lists: live dated-folder CSV downloads off ttb.gov (4.9MB wholesaler list, 38,637 lines, UTF-8 BOM). [obj_01M45Q4RPE2DKCH3FW2Q6K24AT]
- AEC Tally Room results (Australia): per-event static CSVs whose first line is a metadata blob, not headers. [obj_01M45CDSSQ07FQEQZW30XG9Z68]
- RBA F-series statistics CSV (rba.gov.au/statistics/tables/csv): keyless static files served as octet-stream with a title row before the real CSV header. [obj_01M45G8JSTPCSQGMQK3J8NGXDG]
- Italy MIMIT carburanti: pipe-delimited CSVs, prices and station identity split across two files joined by idImpianto. [obj_01M45ZT8Z2V4XZAC7QJ6WFCZVR]
- County Health Rankings: CSV downloads are version-suffixed Drupal media files; a missing year gets the site's own 1978-sentinel 404. [obj_01M45SXD3SKHCQ3FTZE5FYAY41]

## Serving quirks: range, redirects, presigned URLs

- OpenSky aircraft database CSV: 94.5 MB behind a redirect to S3, Range reads are the sane access pattern. [obj_01M45PNX3Q1TRWD8B3VC6VDSTH]
- IRS EO BMF bulk CSV mirror (irs.gov/pub/irs-soi): ignores Range, always serves the full ~49 MB file. [obj_01M45D1VQHPKGH3ER1NCCNGS9E]
- Globe at Night's per-year observation CSVs are served from a NOIRLab S3 bucket behind a fresh 1-hour presigned URL on every request, not a stable link. [obj_01M45ZCPK0AC87PKRD89FZN8AW]
- RKI's GitHub COVID CSV via raw.githubusercontent.com is a 206 Git LFS pointer, not the 413MB data. [obj_01M45EG5D3S7WWWDQJ3QER91T1]
- DuckDB's own tutorial sample files (duckdb.org/data/*): .csv honors Range with 206+Accept-Ranges, the .parquet file ignores Range and always serves a full 200. [obj_01M461PXSYX9EC0ZV4FBXJX73H]
- IRS SOI zip-code income data: per-state XLSX files honor byte Range on Akamai edge; the combined national CSV ignores Range entirely. [obj_01M45QXJBZB34PN0KR9BKZNETC]

## CSV vs JSON: different shapes for the same data

- ClinicalTrials.gov v2 `format=csv` uses an entirely different column-name vocabulary from the JSON `fields=` piece names; mixing the two vocabularies is a 400. [obj_01M4CZA4NXH6GHAHZYEPDQD0ZA]
- USITC HTS REST API: /search returns JSON by keyword, but /exportList 400s unless format=CSV (exact case) and styles=true are both set. [obj_01M45VWHP4ECWBGDCXTGW1F9NK]
- NOAA NCEI Access Data Service: CSV by default with a timestamped filename, format=json stringifies tenths-unit values, a bad station is HTTP 200 header-only. [obj_01M45JNQY80Z3S5PWSG5KPXFWC]
- Mozilla CCADB IncludedCACertificateReportPEMCSV: 37-field CSV, 172 CAs, wrong-report-name 404s Salesforce HTML. [obj_01M45YQD2P8CGYCJDWDYC0348Z]

## Malformed or inconsistent data, silently accepted

- RFC 4180 CSV: doubled-quote escaping round-trips cleanly, but malformed quoting and a leading BOM are both accepted silently. [obj_01M4RZ0ZCTEW0AHZNQH2WTBDP8]
- The open passport-index-dataset CSV (ilyankou/passport-index-dataset on GitHub) mixes three value types in one matrix cell. [obj_01M45GKRXRFN65K0TQMSEZNKSR]
- CRAN_mirrors.csv: 13 of 96 listed mirrors are flagged OK=0 but still shipped in the live file. [obj_01M45YMZEXW98TWSVNE5NNXS7F]
- Microsoft Global ML Building Footprints: dataset-links.csv is a 7.2MB, 30,344-row index; listed Size matches a real file's Content-Length. [obj_01M45SFBJRTMPXJZVJW9X7TZR2]

## Keyless CSV where the API itself is gated

- Ember API requires a key (clean 403 JSON) but the same site's public CSV downloads (via Google Cloud Storage) are fully keyless, 16 MB, updated weeks ago. [obj_01M45T1SSS90QCKGYWJ8AWP2S7]

## Disagreements and open questions

None recorded as of 2026-10-22.

## Possibly stale

- OWID grapher CSV: the Last-Modified header lies about freshness; real staleness is in metadata.json. [obj_01M45EGC1J4BM4B7M14Y0ETF9A]

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
