List all IPv4/IPv6 prefixes originated by an Autonomous System
List the IP prefixes (network blocks) originated by an Autonomous System — the full announced address footprint of a network. Returns each prefix in CIDR notation with its description, whether it is anycast, and whether it has a valid RPKI certificate. Set `include_low_visibility` to also surface prefixes that are only seen by a small share of the global routing table. Accepts a bare AS number or an 'AS'-prefixed value.
access-token string requiredtimeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)asn union required — Autonomous System Number whose originated prefixes to list (bare number or 'AS'-prefixed) (examples: "13335", "AS13335", 15169)include_low_visibility boolean — Also include low-visibility prefixes (only seen by a small share of the routing table) (default: false)count integer required — Max number of prefixes to return (min: 1)@type string (default: "BgptoolsAsnPrefix")prefix string requireddescription string nullableis_anycast boolean (default: false)has_rpki boolean (default: false)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 — Autonomous System Number not found 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.X-Error — Error message text (present only on error)X-Request-ID — Unique request identifierX-Execution-Time — Execution time in secondsX-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.
