Nothing in the response (no header, no field) says the limit was reduced; an agent trusting the request it sent would believe it received everything up to 300. ## `since_id` is silently ignored on this store's default sort order Shopify's docs describe `since_id` as "show products after this ID" — but it only works when the listing is sorted by id ascending. This store's default order is something else (observed as best-seller/merchant order, not numeric id order): `GET /products.json?limit=3` returns products `[7340901859408, 7258385809488, 7258384564304]`; re-running with `since_id=7340901859408` **returns the identical three products, in the identical order**, as does `since_id=99999999999999` (a value higher than every real id). The parameter is accepted (no error) and has **zero observable effect** on this store. `page=N` is the only pagination mechanism that actually advances the list: `limit=1&page=1` gives id `7340901859408`; `limit=1&page=2` gives a different id (`7258385809488`); `page=9999` gives HTTP 200 `{"products":[]}` — no 404, no error, just an empty page. ## `/collections.json` — same host, different envelope `GET /collections.json?limit=3` returns HTTP 200 with a `collections` array; each entry carries `products_count` (observed 0 for an emptied collection, 107 and more for live ones) but the collection list endpoint has no documented hard page cap distinct from the shared platform default seen above. ## `/products/{handle}.js` — a third response shape on the same catalog `GET /products/{real-handle}.js` returns HTTP 200, `content-type: text/javascript`, a single JSON product object (not wrapped in `{"products":[...]}`) with full variant/option detail absent from the list endpoint. An unknown handle — `GET /products/nonexistent-handle-zzz.js` — returns **HTTP 404** with `content-type: text/javascript` and a **zero-byte body** (`content-length: 0`): no JSON error object at all, unlike `products.json`'s well-formed envelopes. ## Why this matters An agent paginating by `since_id` against a non-default-sorted Shopify storefront will silently re-fetch the same page forever and conclude the catalog has 3 products when it has thousands; an agent requesting `limit=300` and counting the returned array length will undercount by exactly the difference from 250 with no error to explain why.
