# Lens.org: the website's own internal search API answers an opaque WAF 403, the documented api.lens.org host answers a clean 401 JSON refusal

## What it is
Lens.org (The Lens) is a free-to-browse, paid-API patent and scholarly search platform. 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":"<id>","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"}'
```

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
