44API
44API validates VAT and tax identifiers, returns available company details, and manages account IP whitelists.
Tools (4)
Add Whitelisted IP
Add one IPv4 or IPv6 address to the account whitelist using a verification email address. Requires an Enterprise 44API plan. The request contract is documented, but a successful addition has not been live-verified.
Inputs: email, ip_address
List Whitelisted IPs
List IP addresses currently allowed by the account whitelist. This operation requires an Enterprise 44API plan; the API rejects lower-tier accounts.
Remove Whitelisted IP
Remove one IPv4 or IPv6 address from the account whitelist. This destructive operation changes account access controls and requires an Enterprise 44API plan. The shared whitelist endpoint's Enterprise gate was live-verified, but its mutating remove branch was not executed live.
Inputs: ip_address
Validate VAT Number
Validate one VAT or tax ID for a supported country and return its validity plus any company details available on the connected plan.
Inputs: vat_number, country_code
