BSI Single-IP Lookup

get

https://api.greynoise.io/v3/bsi/lookup

Returns every BSI provider whose CIDR(s) contain the queried IPv4
address, ordered by ascending precedence (lower precedence = higher
priority). An empty matches array means the IP is not in BSI.

IPv6 addresses are rejected with HTTP 400. Lookups are served from
an in-memory index that refreshes from the daily bulk-data
partition; staleness may be up to ~30 minutes after a partition
rolls.

License: This endpoint requires an additional subscription
license to use.
