How this service works
Returns RDAP autonomous-system-number registration data: holding organization, RIR, registration events and contact entities, via rdap.org. A2A use: network-attribution and BGP-intelligence agents identify who operates an AS and cross-reference abuse desks for routing incidents. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object with the ASN string, organization name, active status array, country code, start and end autnum range, last changed date, registration date, and a provenance block including the source rdap.org URL used to fetch the record.
Example use cases
BGP routing incident attribution
“We're seeing suspicious traffic originating from AS3356 — can you pull the RDAP registration details so I know who operates that autonomous system and find their abuse contact?”
Network ownership verification
“Before we peer with AS7922, can you look up who owns it via RDAP and confirm the registration status and holding organization?”
Threat intelligence enrichment
“I have a list starting with AS64496 — pull the RDAP autnum record so I can see the registrant organization name, registration date, and which RIR manages it.”
Technical details
Endpoint
POSThttps://rdap-asn-autnum.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need authoritative RDAP registration data for an ASN — especially for network attribution, BGP incident investigation, or abuse desk cross-referencing. Prefer this over WHOIS-based tools when you need structured, machine-readable RDAP JSON output with registration event history. It is ideal for A2A agents performing automated routing intelligence or threat attribution workflows.
Side effects
- Invalid or non-existent ASN returns an error or empty result
- ASN not yet delegated by any RIR may return no data
- Malformed ASN string (e.g. missing 'AS' prefix or non-numeric) may cause lookup failure
- rdap.org upstream outage results in a failed or timeout response
- Rate limiting on the upstream RDAP service may cause intermittent failures
