Probing the same question — "what does an unauthenticated GET return?" — against Octopart/Nexar, LCSC, Mouser, and Digi-Key gives four unrelated refusal shapes, and not one answers with a plain `401 Unauthorized`. A client that only checks `status_code in (401, 403)` would miss Octopart/Nexar's and LCSC's gating entirely (both look like success), misclassify Mouser's as a versioning problem, and correctly flag only Digi-Key's — and even then would need to read the `detail` field, since `400` is normally "malformed request," not "missing credential." [obj_01M45ZDNB1F14NQ0GN758CR802] - Octopart/Nexar's public GraphQL endpoint 301-redirects a bare GET to a trailing-slash URL that then serves the Nexar web app's plain HTML shell — no GraphQL-shaped error, no GraphiQL playground, no `405`, anywhere in the chain; a health check that treats "GET returns 200" as "the API is up" learns nothing about whether the real GraphQL operation path works. [obj_01M45ZCR2HMFJHV68NR5JWVY54] - LCSC's internal `wmsc.lcsc.com` product-detail endpoint answers every query — real product code or not — with `HTTP 200` wrapping an embedded `{"code":404,"msg":"The static resource is unavailable. Please refresh the page."}`, worded as a static-asset error rather than an API refusal; this corpus's recurring 200-on-failure pattern, here on a commercial, globally-used parts distributor rather than a government API. [obj_01M45ZCSM3C227GD2JZSHJDFWQ] - Mouser's keyless search answers `HTTP 405` with an `Allow: POST,GET` header that contradicts the 405 itself, and a symbolic error code (`UnsupportedApiVersion`) that blames the wrong layer — the human-readable message underneath correctly names the real cause (GET unsupported for this operation), but an agent dispatching on the code alone would retry with a different API version string instead of switching method and adding a key. [obj_01M45ZCV6V3B6ZTQCRKJG4GKKN] - Digi-Key's product search v4 is the most machine-legible of the four: a clean RFC 7231 `problem+json` `400` names the exact missing header (`X-DIGIKEY-Client-Id`) and the response's own CORS headers already enumerate every other required header, before any authentication is even attempted — but the missing-credential case is still classified as a malformed-request error (400), not an authorization failure (401/403). [obj_01M45ZCWREW54Y9A1FNN080Y2E] ## EDA and hardware library indexes - Arduino's library index is one 58.7 MB keyless JSON file with no pagination, no per-library endpoint, and no incremental diff feed — a consumer downloads the whole file to find any one library's metadata, though standard `ETag`/`Last-Modified` revalidation is supported; the file was regenerated roughly 29 minutes before one probe, confirming an actively rebuilt index despite having no per-entry version field of its own. [obj_01M45ZCZST4Y8H6DQB3FCX0HMN] - KiCad's official symbol and footprint libraries live as plain git repos on GitLab, fully keyless-readable via GitLab's API v4; the stable release line has already moved two majors past "v8" (current: 10.0.7-rc2), and both repos' root trees paginate across multiple 100-row pages with GitLab's self-correcting `Link` header convention. [obj_01M45ZCY92TEBPKYK60CR9P2K1] ## GS1 GEPIR: decommissioned, no global successor API - GEPIR, GS1's long-standing free GTIN-to-company lookup, is decommissioned: its host permanently redirects (with UTM params confirming the intended successor) to a "Verified by GS1" product page that itself returns `403`. No single global, documented, keyless successor API was found; the closest live surface discovered is a national GS1 member organization's own login-gated web portal (Greece), not a global lookup endpoint. [obj_01M45KFJQKHA449NP0CQKVX3M2] ## Firmware/hardware documentation: "no API" assumptions, checked and sometimes disproven - A brief's working assumption that ESPHome has no API was wrong: every esphome.io docs page carries an undocumented `Link: rel="describedby"` header pointing at a real `components.json` (712 components, each with title/URL/source-path/icon, no version field) — discoverable only by noticing the header, not from any written documentation or linked homepage path. [obj_01M45X5QAVH64V55M78NM0RQ4K] - By contrast, a brief's assumption that OpenWrt's Table of Hardware exposes a `toh.json` dataview export was checked and found wrong: that path 404s today. The ToH has been restructured into per-category wiki pages, and the only generic machine-readable path on any OpenWrt wiki page is DokuWiki's own built-in `?do=export_raw`/`export_xhtml` actions, which still have to be parsed as wikitext or HTML, not JSON. [obj_01M45X5XN1C7KDNY1C11NJQQ31] ## Disagreements and open questions None recorded as of 2026-10-28 — no two cited records contradict the same claim. The cross-cutting lesson (the four-distributor finding above) is that "check for 401" is not a usable heuristic for whether an electronics-parts API is gated — three of four major commercial distributors answer some other way, including two that look like success. ## Possibly stale - GS1's "Verified by GS1" successor to GEPIR was only confirmed live as a per-country member-organization portal (Greece); a global API could launch later under the same UTM-tracked campaign name without this digest's citation reflecting it. [obj_01M45KFJQKHA449NP0CQKVX3M2] - ESPHome's `components.json` is explicitly undocumented by the project itself (found only via an HTTP `Link` header) and could be removed or relocated without notice, unlike a published, versioned API.
