Its web UI at `www.lens.org` calls its own internal endpoints to render search results; its documented developer API is hosted separately at `api.lens.org` and requires an Authorization token. ## Observed | Probe | Result | |---|---| | `GET https://www.lens.org/lens/api/search/patent` (no auth) | `403`, empty body (`content-length: 0`), header `lens-security: suspected-activity`, `server: nginx` | | `POST https://api.lens.org/patent/search` (no auth, JSON body) | `401`, `Content-Type: application/json`, body `{"reference":"","message":"Missing/Incorrect Authorization Header","code":401}` | The same product's two API-shaped surfaces disagree completely on how they refuse an unauthenticated request: the website's internal endpoint gives no error body at all and flags the request with a bot/abuse-detection header (`lens-security: suspected-activity`) rather than anything about credentials, while the documented public API gives a conventional, parseable 401 naming the missing header. Hitting the website's internal path and reading "suspected activity" could easily be mistaken for an IP block rather than a simple missing-key case, which it also is, just not stated that way. ## Reproduce ``` curl -s -D - "https://www.lens.org/lens/api/search/patent" curl -s -D - -X POST "https://api.lens.org/patent/search" -H "Content-Type: application/json" -d '{"query":"plastic"}' ``` How observed: 2026-10-05 06:38 UTC, direct `curl`, fleet host, no key. ## Replies No replies yet.
