`limit=100000` → `HTTP 400`, `{"code":3200,"message":"Incorrect request [limit must be a number greater than 0 and maximum is 100]","line_number":142,"property":"limit"}`. - **UK Find a Tender** — same default/cap **100** rows, same OCDS 1.1 payload shape, but `limit=10000` → `HTTP 400`, `{"timestamp":"...","status":400,"error":"Bad Request","message":"'limit' must not exceed the maximum value","path":"...","exception":"Invalid argument"}` — a Spring Boot default-handler shape sharing zero field names with its sibling UK service's `code`/`line_number` shape. - **AusTender** — also caps at **100** rows per page, independent of date-range width (a 4-day window and a ~9-month window both returned exactly 100 releases); its own refusal uses a third, unrelated shape: `{"errorCode": 102, "message": "Date: Invalid Date Value [...]"}`. - **CanadaBuys** — opts out entirely in the direction of *more*: a single unbounded 6.2 MB CSV bulk export, no pagination parameters at all, the whole current dataset every time. - **Open Contracting Data Registry** (the cross-national directory meant to help a client discover all of the above) — opts out in the direction of *none*: no JSON API exists at all behind its search UI; `Accept: application/json` and `format=json` are both silently ignored and full HTML is returned regardless, despite the product's own description promising JSON/Excel/CSV as *download* formats for the datasets it indexes. Three governments converged on roughly the same ~100-row-per-request ceiling for OCDS release- package search — a real, useful fact for anyone budgeting request counts against a procurement monitoring job — but implemented the refusal for exceeding it with three structurally incompatible JSON error bodies (`code`+`line_number`+`property`; Spring's `timestamp`+`status`+`error`+`path`+ `exception`; `errorCode`+`message`), meaning generic "read the 400 body for the limit" error- handling code cannot be shared across them even though the success-path OCDS payload is identical by design (it's the same open standard). Meanwhile the two outliers bracket the pattern from opposite ends: CanadaBuys never needs pagination because it publishes everything as one file, and the Open Contracting Data Registry — despite sitting conceptually "above" all of these national APIs as a discovery layer — has no query API of its own at all, so a client cannot discover the national endpoints programmatically; it has to already know the direct URLs this lane's other records document.
