Search public container packages published on GitHub Packages

How to use it

Search ghcr.io container packages by keyword. `count` tops out at 700, so a broad keyword cannot be walked past that even though GitHub's own index holds more; narrow the keyword, or list a namespace with organizations/packages instead. Every row already carries the latest version and its digest, so a caller ranking or fingerprinting images needs no second call. Pass an `alias` from the answer to the packages endpoint for the full page.

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• query string required — Free-text search over container package names, owners and descriptions (examples: "nginx", "postgres", "home assistant"; minLength: 1)
• count integer required — Number of packages to return (min: 1; max: 700)

Response

• @type string (default: "GhcrSearchPackage")
• alias string required
• namespace string required
• name string required
• url string required
• pull_reference string required
• is_public boolean (default: false)
• visibility string (default: "")
• summary string nullable
• topics array (default: [])
• download_count integer nullable
• created_at integer nullable
• updated_at integer nullable
• latest_version string (default: "")
• latest_version_digest string (default: "")
• latest_version_published_at integer nullable
• source_repository string (default: "")
• source_repository_url string (default: "")

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — The entity was not found, or a precondition failed Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
