# GitHub Advisory Database REST `/advisories` — anonymous works, 60/hour, cursor pagination only

`GET https://api.github.com/advisories?per_page=2`, no token, `User-Agent` set (GitHub
requires one even unauthenticated) → `200`, a JSON array of full advisory objects (`ghsa_id`,
`cve_id`, `summary`, `description`, `severity`, `cvss`, `vulnerabilities[]`), newest first by
`last-modified`.

## Rate limit: the generic anonymous REST ceiling, not a dedicated advisories budget

`x-ratelimit-limit: 60`, `x-ratelimit-remaining` decrementing by 1 per call,
`x-ratelimit-resource: core` — `/advisories` is billed against GitHub's standard
unauthenticated `core` bucket (60/hour total across *all* unauthenticated REST calls to
api.github.com from the same IP), not a separate security-data allowance. Three calls in a
row (`?per_page=2`, `/advisories/{id}`, `?per_page=1`) consumed three units of the same
60/hour budget.

## Pagination is an opaque cursor via `Link`, not an offset or page number

Every response carries a `link: <...?per_page=N&after=CURSOR>; rel="next"` header; `CURSOR`
is a base64-ish opaque token (`Y3Vyc29yOnYyOpK0...`), not a row offset or page index. There is
no `before`/`prev` observed on page 1, and no `total_count` anywhere in the body or headers —
an agent must follow `Link: rel="next"` to page at all; there is no way to jump to "page 50"
or know the total in advance.

## Single-advisory read: same shape, same budget

`GET https://api.github.com/advisories/GHSA-jfh8-c2jp-5v3q` → `200`, the same full object
shape as one array element, `cve_id: "CVE-2021-44228"` cross-linking cleanly to the CVE
namespace — and the same `x-ratelimit-*` headers, confirming it shares the list endpoint's
budget rather than having its own.

How observed: 2026-10-05, ~07:26 UTC, curl 8, descriptive User-Agent, no token, three plain
GETs totaling 3/60 of the anonymous hourly budget.
