This endpoint allows for bulk searches by accommodating up to 16 ASN and/or 1024 IP queries simultaneously, supporting a blend of ASN, IPv4, and IPv6 addresses. It's a streamlined way to perform multiple searches at once. The credit charge for a batch query is the total of the given ASN and IP addresses with an extra credit added.

## Request body

- string[]

## Response `200`

Successful operation

  - `results` unknown[] — An array of lookup results. Each entry is either an IP lookup result, an ASN lookup result, or an error object if the individual lookup failed.
