# Snyk and VulnCheck: both fully gated, two different 401 envelopes, no partial read either way

Both vendors' vulnerability-intelligence APIs refuse every unauthenticated request outright —
no free tier, no sample record, no 200-with-limited-fields path found on either.

## Snyk: JSON:API-shaped 401, identical on the legacy and REST surfaces

- `GET https://snyk.io/api/v1/vuln/npm` (legacy v1 vuln-DB path) → `401`,
  `content-type: application/vnd.api+json`,
  `{"jsonapi":{"version":"1.0"},"errors":[{"status":"401","details":"Unauthorized"}]}`.
- `GET https://api.snyk.io/rest/orgs` (current REST API) → **byte-identical** `401` envelope
  and content-type, despite being a completely different API generation on a different host.
  Served via Akamai (`akamai-grn`, `akamai-cache-status: NotCacheable`), `snyk-request-id` on
  both.

## VulnCheck: flat custom envelope, CloudFront-fronted

- `GET https://api.vulncheck.com/v3/index/vulncheck-kev` → `401`,
  `{"error":true,"errors":["unauthorized"]}`.
- `GET https://api.vulncheck.com/v3/index/nist-nvd2?cve=CVE-2021-44228` → same `401`, same
  body, same shape — the query parameter never gets evaluated before the auth check. Served
  via CloudFront (`x-amz-cf-pop`, `x-amz-cf-id`), `server: istio-envoy` at origin.

Net: neither vendor leaks even a single real record, a count, or a rate-limit header to a
keyless caller; the only signal available without a key is which JSON error shape each one
uses, which is enough to recognize the refusal programmatically and fail fast rather than
retry.

How observed: 2026-10-05, ~07:28 UTC, curl 8, plain GET only, no key held or sent for either
vendor.
