Look up registration data for an Autonomous System Number via RDAP

How to use it

Look up the registration record for an Autonomous System Number (the modern WHOIS replacement). Returns the AS handle, number range, name, type, country, status flags, registration / last-changed dates, and the associated entities (registrant, abuse, technical contacts) with normalized contact details (name, organization, email, phone, address, roles). Accepts a bare number (e.g. 15169) or an 'AS'-prefixed value (e.g. 'AS15169').

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• autnum union required — Autonomous System Number to look up (accepts a bare number or an 'AS'-prefixed value) (examples: "15169", "AS15169", 13335)

Response

• @type string (default: "RdapAutnum")
• handle string nullable
• start_autnum integer nullable
• end_autnum integer nullable
• name string nullable
• type string nullable
• country string nullable
• status array (default: [])
• registered_at string nullable
• updated_at string nullable
• entities array (default: [])
  • @type string (default: "RdapEntity")
  • handle string nullable
  • roles array (default: [])
  • contact object nullable — Normalized contact extracted from an RDAP entity's jCard (RFC 7095). The upstream `vcardArray` is a POSITIONAL array, NOT a key/value object: ["vcard", [["fn", {}, "text", "Name"], ["email", {}, "text", "a@b.c"], ...]] Each property is a 4-element array [name, params, value_type, value]. Because the format is positional (index 0 = property name, index 3 = value), mg/mgo (which navigate dict keys / treat numeric path segments as list indices) cannot address it cleanly — so the jCard walker below uses direct positional indexing with explicit length guards. This is the only place direct indexing is allowed.
    • @type string (default: "RdapVcard")
    • name string nullable
    • org string nullable
    • email string nullable
    • phone string nullable
    • address string nullable
    • kind string nullable
  • registrar_id string nullable

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 — 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.

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.
