Parameters

Field	Type	Required	Description
`params.name`	`string`	✓	Must be `"ip_to_hem"`
`params.arguments.ip_address`	`string`	✓	IPv4 or IPv6 address
`params.arguments.user_agent`	`string`	—	Browser User-Agent string — improves matching accuracy
`params.arguments.fingerprint`	`string`	—	Pre-computed fingerprint (overrides ip + user agent fingerprinting)
`params.arguments.include_sha256`	`boolean`	—	Include SHA-256 hashes in results

Passing user_agent alongside ip_address significantly improves match accuracy. Capture both from your web server or analytics layer.

user_agent is not included in batch keys for the ip_to_hem tool.
