## Probe

```
GET https://www.pantone.com/api/v1/colors
User-Agent: nh-b29b-pwx-scout/1.0
```

## Observed

HTTP 404, `content-type: text/html; charset=utf-8`, `x-powered-by: Next.js`. Body is the
site's Next.js client-side error shell (`<html id="__next_error__">...`), not a JSON error —
the request hit the Next.js app router and got its generic not-found page, meaning
`/api/v1/colors` is not a route this app serves at all, guessed or otherwise.

A second probe followed Pantone's own in-app link text ("Connect API"):

```
GET https://www.pantone.com/connect/api
```

HTTP 301 → `Location: /na/en-us/color-finder/api` — a plain marketing page slug under the
"Color Finder" section, not an API base path. Following it lands on human-readable product
copy for Pantone Connect (a paid subscription product with an SDK/plugin, not a documented
public REST endpoint reachable without an account).

The 404 page itself carries `<meta name="robots" content="noindex"/>` and
`cache-control: private, no-cache, no-store, max-age=0, must-revalidate` — the site is
explicitly telling crawlers and caches not to keep this response, consistent with a
genuinely-missing route rather than a cached stale miss. The response is served through
CloudFront (`x-amz-cf-pop: SFO53-P8`, `x-cache: Error from cloudfront`), i.e. the 404
reached the Next.js origin and came back through the CDN uncached.

## Conclusion

No live, public, keyless Pantone color-lookup REST API was found at either the guessed
technical path or the vendor's own in-product link. Pantone Connect exists as a commercial
product (API access requires a paid account and is not exercised here — refused, not
asserted). Pantone color data for this corpus's purposes is therefore a **refusal**: there
is nothing to probe without credentials this lane does not hold, and the site actively
marks its own 404 page non-cacheable and non-indexable rather than serving a generic static
error.

How observed: 2026-10-05T09:26:24Z–09:26:25Z, curl GET (plain, `-A` identifying UA), both
requests anonymous, no retries needed — both responses were immediate and deterministic.

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.
