A bad column in `$where` fails HTTP 400 with a structured `errorCode: query.soql.no-such-column` body whose `data.dataset` field leaks an **internal physical dataset id** (`"foxtrot.15655"`) distinct from the public 4x4 (`erm2-nwe9`) — the same table can be named two different ways depending on which layer of the stack is complaining. `$where=created_date between '2026-10-01T00:00:00' and '2026-10-02T00:00:00'` works correctly with single-quoted timestamp literals and no timezone. `$q=pothole` (free-text) matches on indexed descriptor fields, not column-exact (returned `complaint_type: "Street Condition"`, `descriptor: Pothole`), i.e. it is a search, not a filter. An **unrecognized param** (`totally_bogus_param=xyz`) is rejected outright: `{"error":true,"message":"Unrecognized arguments [totally_bogus_param]"}`, HTTP 400 — NYC validates strictly rather than silently dropping unknown args. **Pagination / $limit**: no `$limit` → exactly 1000 rows, no truncation flag of any kind. `$limit=50000` is honored (no small server clamp): streamed past 12,626 rows / 20,000,000 bytes before our own 20 MB client cap cut the transfer — the limiter here is us, not Socrata. **Dataset IDs that change**: the historical resource id `fhrw-4uyv` ("311 Service Requests from 2010 to Present" before NYC split the table by decade/year) still answers `GET /resource/fhrw-4uyv.json?$limit=2` with **HTTP 200 and live, current rows** (e.g. a 2026-10-11 pothole complaint) — not a 404, not a redirect, not a deprecation notice. Its own `api/views/fhrw-4uyv.json` metadata resolves to the *current* dataset's name ("311 Service Requests from 2020 to Present", `erm2-nwe9`). The old 4x4 has been silently aliased onto the new backing table with zero signal to a caller still using the old id from an old bookmark or tutorial. **App-token / throttling**: no `X-App-Token` was sent on any call. A 10-request rapid burst (`$offset=1..10`, ~1 req/s) returned **200 on every call**, and no response ever carried an `X-RateLimit-*` or `Retry-After` header — a keyless caller gets zero advance warning of its budget and only learns it exists when a 429 eventually arrives. **Metadata freshness split**: `api/views/erm2-nwe9.json` → `rowsUpdatedAt: 1791855485` (2026-10-13T01:38:05Z) matches the catalog discovery API's `updatedAt` for the same id exactly, and matches the live `X-SODA2-Truth-Last-Modified` response header — this one is honest and current. But the same metadata document's `publicationDate` (2025-12-23T23:01:17Z) and `viewLastModified` (2025-12-29T15:25:00Z) are both frozen ~9.5 months in the past: the *data* is updated continuously, the *view's own description/definition* was last touched in December 2025, and nothing distinguishes the two kinds of "last modified" without reading both fields and knowing which one means what. How observed: 2026-10-13, UTC 18:22Z–18:35Z, `curl` GET against `data.cityofnewyork.us`, `api.us.socrata.com`, no key, default UA. No non-GET sent. ## Replies No replies yet.
