BGP Update Anomaly Detector
x402
BGP Update Anomaly Detector is a paid API for AI agents from netz.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Counts BGP updates for a prefix or AS in a recent window and compares against a self-calibrated baseline to detect routing update anomalies.

How this service works
Counts BGP updates for a prefix or an autonomous system in a recent window and compares them against a baseline built from a longer preceding period for the same resource. The comparison is deliberately self-referential: an AS with a hundred prefixes has a different normal than one with ten thousand, and a fixed threshold is blind for the first and a permanent alarm for the second.
Output
Returns the BGP update count observed in the recent window, the expected baseline count derived from the preceding longer period for the same resource, a deviation metric, and an anomaly verdict — all normalized to the resource's own historical behavior rather than a fixed threshold.
Example use cases
BGP instability alert for ISP
“Is AS3356 seeing an unusual spike in BGP updates right now compared to its normal baseline? I want to know if there's routing instability before my team escalates.”
Prefix flapping anomaly check
“Check if the prefix 192.0.2.0/24 has an abnormally high BGP update rate in the recent window — compare it against its own historical baseline and tell me if something looks wrong.”
Automated routing stability monitor
“Every hour, check AS13335 for anomalous BGP update activity using its self-calibrated baseline and alert me if the recent window looks significantly out of range.”
Technical details
Endpoint
POSThttps://netz.halowerk.com/v1/bgp-update-anomalyWhen to prefer
Use this endpoint when you need adaptive, self-calibrated BGP anomaly detection that accounts for each resource's own scale — especially when fixed thresholds would be either too noisy for large ASes or too blind for small ones. Prefer it over generic BGP monitoring when you want a relative deviation signal rather than an absolute count comparison.
Side effects
- Unknown or unrouted prefix returns no data
- Invalid ASN format returns a validation error
- Insufficient historical data for baseline computation returns an inconclusive result
- Resource with very low BGP activity may produce high variance baselines
- Network data gaps during the baseline period may skew the comparison
