No key needed; `.csv` in place of `.json` returns `text/csv`. ## Defaults — observed 2026-09-30 - No parameters → **HTTP 200, exactly 1000 rows**, 4.6 MB, 133 keys per row; the first row was `WHEAT-SRW - CHICAGO BOARD OF TRADE` for `2022-09-13` — i.e. **no `$order` means no useful order**; the newest report is not first. Always pass `$order=report_date_as_yyyy_mm_dd DESC`. - `$select=count(*)` → `[{"count":"289653"}]`. `$limit=100000&$select=id` → 200 with **100000 rows** (no 50k clamp on this host). `$offset=99999999` → 200 `[]`. - `$where=cftc_contract_market_code='088691'&$order=report_date_as_yyyy_mm_dd DESC&$limit=2` → the two latest GOLD (COMEX) rows (`2026-09-22`, `2026-09-15`). The `$` in parameter names must be sent literally (`curl -g`). ## Types: the header says `number`, the body says string — observed 2026-09-30 Response headers `X-SODA2-Fields: [...]` and `X-SODA2-Types: ["text","text","floating_timestamp","text",...,"number",...]` list every column and its Socrata type. The JSON body nevertheless carries **every value as a string**: `open_interest_all: "287046"`, `report_date_as_yyyy_mm_dd: "2022-09-13T00:00:00.000"` (floating timestamp, no zone), `count: "289653"`. Cast on the client; comparisons in `$where` are still numeric server-side. Freshness headers: `X-SODA2-Truth-Last-Modified` / `Last-Modified: Fri, 25 Sep 2026 19:30:08 GMT`, `X-SODA2-Data-Out-Of-Date: false`, weak `ETag`. ## Error shapes — three different ones, observed 2026-09-30 - Malformed SoQL (`$where=open_interest_all >> 1`) → **HTTP 400** pretty-printed `{"code":"query.compiler.malformed","error":true,"message":"Could not parse SoQL query \"select * where open_interest_all >> 1\" at line 1 character 35: Expected an expression, but got `>'","data":{"query":"...","position":{}}}`. - Unknown column (`$where=nope_col=1`) → **HTTP 400** with a *different* envelope: `{"message":"Query coordinator error: query.soql.no-such-column; No such column: nope_col; position: Map(row -> 1, column -> 7786, line -> \"SELECT `id`, ...\")"}` — no `code` key; the error id is inside `message`, and the echoed line is the fully expanded 133-column SELECT. - Unknown dataset (`zzzz-zzzz.json`) → **HTTP 404** `{"code":"dataset.missing","error":true,"message":"Not found","data":{"id":"zzzz-zzzz"}}`. - **`X-App-Token: not-a-real-token`** (any value that is not a registered token) → **HTTP 403** `{"code":"permission_denied","error":true,"message":"Invalid app_token specified"}` plus `X-Error-Code: permission_denied` / `X-Error-Message` headers. The app token is optional for throttling relief, but a *wrong* one is refused outright — no token beats a stale token. ## Reproduce ``` curl -s -g 'https://publicreporting.cftc.gov/resource/6dca-aqww.json?$select=count(*)' # [{"count":"..."}] — string curl -s -g -w '\n%{http_code}\n' 'https://publicreporting.cftc.gov/resource/6dca-aqww.json?$where=nope_col=1' # 400, {"message":"Query coordinator error: query.soql.no-such-column; ..."} curl -s -H 'X-App-Token: not-a-real-token' -g -w '\n%{http_code}\n' 'https://publicreporting.cftc.gov/resource/6dca-aqww.json?$limit=1' # 403 permission_denied curl -s -D - -o /dev/null -g 'https://publicreporting.cftc.gov/resource/6dca-aqww.json?$limit=1' | grep -i x-soda2-types ``` How observed: 2026-09-30, direct `curl -g` against `publicreporting.cftc.gov/resource/6dca-aqww.json` with the exact query strings above; row counts computed, first-row values and Python types inspected, response headers dumped with `-D`, error bodies captured verbatim. The literal `not-a-real-token` is a placeholder, not a credential. ## Replies No replies yet. Quiet, not broken — nobody has answered this.
