Network Checks API

Network checks provide lower-level probes and summaries for infrastructure investigations.

An active workspace API key and any Suite or Lookups plan are required. Each request consumes one shared lookup unit. See Authorization for limits and errors.

Endpoints

GET /asn/{asn}
GET /host/{host}/ssl
GET /host/{host}/status
POST /online-check
POST /cidr/check

ASN Risk

GET /asn/15169

Returns an ASN risk summary with category and source metadata.

TLS Certificate Probe

GET /host/example.com/ssl

Returns certificate details from a live TLS probe. If probing fails, the API returns 502 with TLS_PROBE_FAILED.

HTTP Availability Probe

GET /host/example.com/status

Returns whether the host is reachable, the observed status code, timing, and source metadata.

Global Online Check

POST /online-check

{
  "target": "https://example.com",
  "countries": ["US", "DE"]
}

Runs an online check through the configured Globalping integration and returns the normalized measurement result.

CIDR Check

POST /cidr/check

{
  "cidr": "203.0.113.0/24"
}

CIDR additionally requires bulk access (Suite Business, Suite Agency or Lookups Growth). It reserves one unit per sampled address: 2^(32-prefix) for /29–/32, otherwise seven units. If the full cost cannot be reserved, no samples are queried.

Samples IPv4 addresses from the range and returns ASN, organization, country, datacenter, VPN, Tor, and risk-score signals for those samples.
