FLATFILES requests
The interactive builder above generates per-contract MDDS (request/response) snippets. Whole-universe FLATFILES requests use a different parameter set — (sec_type, req_type, date) instead of (symbol, start, end) — and ship as a separate surface in the SDK. Below is the same snippet shape for FLATFILES so you can construct calls in the same builder pattern.
Parameters
| Parameter | Values | Required |
|---|---|---|
sec_type | OPTION, STOCK, INDEX | yes |
req_type | EOD, QUOTE, OPEN_INTEREST, OHLC, TRADE, TRADE_QUOTE | yes |
date | YYYYMMDD string | yes |
format | csv, jsonl | optional (defaults to csv for the on-disk path; the in-memory path returns typed rows) |
output_path | filesystem path | optional (the on-disk paths only) |

# Python — typed terminal:
rows = tdx.flat_files.option_quote(date="20260428")
rows.to_polars() # or .to_pandas() / .to_arrow() / .to_list()
# Python — bytes on disk:
tdx.flatfile_to_path("OPTION", "QUOTE", "20260428", "out.csv", "csv")ts
// TypeScript:
const rows = await tdx.flatFiles.optionQuote('20260428');
rows.toArrowIpc();bash
# CLI:
tdx flatfile quotes 20260428 --format csv -o spy_quotes.csv
