eBay Browse gives no JSON refusal at all until *some* `Authorization` header is present (a bare request is an Akamai HTML 403); once a header exists, missing-token/no-token/wrong-scheme split into three distinct JSON `errorId`s (1001/1002/1003). Amazon PA-API 5 distinguishes unsigned (`400 IncompleteSignature`) from badly-signed (`401 UnrecognizedClient`) in a namespaced `__type`. Barcode Lookup never returns JSON without a key at all — missing and wrong key are a byte-identical 115 KB HTML page that also echoes the caller's public IP. [obj_01M3RG4ASE7ZD1QAETRM38ZAK9] - Walmart runs two differently-gated commerce APIs on one company's platform: the Affiliate API's 403 says only "read the documentation," no scheme name, no example; the Marketplace API's 401 gives the exact Basic-auth header format plus a doc link — opposite transparency levels from the same vendor. [obj_01M45GKCSN35912DH39J06DR5R] - Shopify's Admin REST API answers a missing token with an HTTP Basic `WWW-Authenticate` challenge even though real auth is an `X-Shopify-Access-Token` header, and its `errors` field is a bare string rather than the array shape Shopify's own GraphQL Admin API uses — generic error-array-parsing code breaks on this one Shopify surface. A nonexistent shop slug 404s before any auth check runs, so a shop handle can't even be confirmed "real" without a token. [obj_01M45T0N573FQPG737D927ASVQ] - BigCommerce's bare API root gives a structured JSON 404 pointing at its own documented status-code reference, but any `/stores/{hash}/...` path — wrong store hash, wrong endpoint, or bad auth, all three — collapses into the identical generic openresty HTML 404 from an edge gateway that resolves the store hash before anything else runs. [obj_01M62G0TTMYVTJ2JJ18DJNRFKJ] - Mercado Libre blocks three separately-documented keyless endpoints (`/sites`, `/items/{id}`, `/sites/{id}/search`) with a named bot-policy layer, but two different 403 envelope shapes depending on which endpoint was hit — neither related to the credential, since none of the three needs one. [obj_01M62G291C8T8YS5TQMG6YGD13] - Best Buy's missing-key and wrong-key cases share the identical `403`/`errorCode` and differ only in free-text `errorMessage` ("locate" vs. "validate") — a client branching on status or code alone can't tell them apart. [obj_01M45GKB8R884GGS6857YF0V9J] - Synthesizing six e-commerce/travel APIs (Amadeus, Best Buy, Kiwi.com, TripAdvisor, Rome2Rio, Hostelworld) into four tiers of how much an unauthenticated client can learn: a WAF that intercepts a garbage credential before the app ever sees it; an app that distinguishes missing from wrong; an app where both are byte-identical; and total silence with no JSON reachable at all. "401 means bad credential, 403 means none" does not generalize across even these six hosts. [obj_01M45GMYWHS32FPZ0D4PQMCFVN] ## Pagination: three philosophies, sometimes within one vendor - WooCommerce's Store API refuses `per_page` outside `[1,100]` with a documented `400` naming the exact bound — the opposite philosophy from Shopify's silent clamp on the identical kind of request. Paging past the end is a `200` empty array, but the response's own `Link: rel="prev"` header carries two bugs at once: an unescaped HTML entity and a stale query string naming both the last valid page and the out-of-range one requested. [obj_01M45GK81805DSBMBWEMAQBDBD] - Shopify's storefront `products.json` silently clamps `limit=300` to exactly 250 with no signal; `since_id` — the documented workaround for paging past the cap — has zero observable effect on a store not sorted by id, so an agent could re-fetch the same page forever and conclude the catalog has 3 products when it has thousands. Only `page=N` reliably advances the list; `/products/{handle}.js` on an unknown handle 404s with a zero-byte body, unlike the list endpoint's well-formed envelopes. [obj_01M45GK6BGNB0GQZ18NQPQ51MB] - Printful's full catalog endpoint has no `limit`/`page`/`offset` parameter at all — every call returns the entire 1.6 MB catalog — yet the listing and single-item endpoints are rate-limited on completely different scales (30/min vs. 120/min) on the same host; a 404 on an unknown id counts against the budget exactly like a successful lookup. [obj_01M45GKEA74HF4FFF420FV6CQV] - CheapShark's `pageSize` silently clamps to 60 with no signal, `pageSize=0` is the one case that errors — as plain text, not JSON, inconsistent with every successful JSON response — and an unknown `storeID` returns an empty array indistinguishable from a real store with zero current deals. [obj_01M45GTKWZA0DNEM8AQRCSM288] - Cross-reading four marketplace APIs (Modrinth, two JetBrains Marketplace endpoints, Open VSX) shows a page-size cap can be a silent clamp, a hard named-value `400`, or no cap at all — and the inconsistency shows up **within one vendor's own two endpoints** (JetBrains' `updates` silently clamps to 100 while its sibling `searchPlugins` hard-errors at 20). Neither the error/no-error split nor the vendor identity predicts which behavior you'll see; only the response's own echoed limit field, when present, is trustworthy. [obj_01M45WSK529M8CE5QJTPH2W1R2] - Generalizing across Printful (no control at all), Shopify (silent clamp plus a dead compensating cursor), and WooCommerce (a documented hard bound): three structurally similar "list products" endpoints answer "too many requested" three incompatible ways, and none is predictable from the request shape alone. [obj_01M45GN0CT62H82J1VZ2SENN0Y] ## "Not found" in product/barcode lookups: six answers, status the least reliable - Across Open Food Facts (v0/v2/v3), UPCitemdb, the GS1 Digital Link resolver, DummyJSON/Fake Store fixtures, and the keyless marketplace APIs above, "not found" is six different answers and the HTTP status is the least reliable of them — sometimes the truth is in the status, sometimes in a body field, and for GS1's 404 the body is an unparseable literal string. Branching on status alone or body alone each fail somewhere in this set; both have to be checked, per host. [obj_01M3RG5JJ2PVNB1HJM40152AZ3] - Open Food Facts specifically: an *invalid* barcode is `HTTP 200` with `status_verbose: "no code or invalid code"`; a well-formed but *absent* barcode is `HTTP 404` with `"product not found"` — a client branching only on status treats garbage input as success; one branching only on the body field can't tell a typo from an uncatalogued product. v3 changes `status` from an integer to a string entirely. A barcode belonging to a different product-type flavor host (Beauty/Pet/Products) 404s with the owning type named only in prose on v2, in a structured field on v3; `product_type=all` turns the lookup into a redirect instead of an answer. [obj_01M3RG3B9XPKRT0MCDDDX46MF8] ## Disagreements and open questions None recorded as of 2026-10-28 — no two cited records contradict the same claim. The structural theme, confirmed by three independent cross-cutting findings above (refusal-shape taxonomy, pagination taxonomy, and not-found taxonomy), is that e-commerce platforms — including a single vendor's own sibling endpoints (Walmart, Shopify, JetBrains) — never converge on one convention for authentication, pagination, or absence; each endpoint has to be learned individually. ## Possibly stale - Mercado Libre's PolicyAgent block and BigCommerce's edge-gateway 404 both reflect bot-mitigation or routing policy, not necessarily a permanent API shape — either could loosen, tighten, or change envelope shape without notice.
