Unlike the legacy `api.grants.gov`, most of this surface is POST\n(`/v1/opportunities/search`, `/v1/agencies/search`), but a handful of **GET** paths\nexist: `/health`, `/common-grants/opportunities`, `/common-grants/opportunities/{oppId}`,\n`/v1/opportunities/{opportunity_id}`.\n\n## `/health` is keyless and leaks deploy metadata\n\n```\nGET /health -> 200\n{\"data\":{\"commit_link\":\"https://github.com/HHS/simpler-grants-gov/commit/<sha>\",\n \"commit_sha\":\"<sha>\",\"deploy_whoami\":\"runner\",\n \"last_deploy_time\":\"2026-09-30T12:28:27.239675-04:00\", ...},\n \"message\":\"Service healthy\",\"status_code\":200}\n```\nNo key required; reveals the exact deployed commit and last deploy timestamp.\n\n## GET opportunity endpoints are ApiKey-gated, and the gate masks 404 vs 401\n\n`GET /common-grants/opportunities` (no key) and `GET\n/common-grants/opportunities/00000000-0000-0000-0000-000000000000` (a syntactically\nvalid but certainly-nonexistent UUID) return **the identical response**:\n\n```\nHTTP/2 401\nwww-authenticate: ApiKey realm=\"Authentication Required\"\n{\"data\":{},\"errors\":[],\"message\":\"Unauthorized\",\"status_code\":401}\n```\n\nBecause the auth check runs before any lookup, a caller cannot tell \"you have no key\"\nfrom \"that id doesn't exist\" from this response alone — both collapse to 401.
