Tools (8)

• check_uk_business262 tok

  Sourced check of a UK company from Companies House: status, type, incorporation date, registered office, SIC codes, filing health (accounts and confirmation statement overdue and by how many days, plus the GOV.UK late filing penalty band if accounts are overdue), insolvency and charges flags, active officers and PSCs, each with a source_url. VAT check: coming soon (a vat_number is accepted but not checked yet). Not a credit check, sanctions or PEP screening. Counts as 2 calls on an API key plan. Paid: $0.02 USD per call via x402, or use an API key (see /pricing).

• calculate_employer_ni259 tok

  Paid. Calculates employer Class 1 National Insurance for one or more annual salaries on a date using verified UK Rules data. Use this instead of doing the maths yourself. Paid: $0.005 USD per call via x402, or use an API key (see /pricing).

• get_rate220 tok

  List UK tax/payroll deadlines. Fixed-date deadlines get the next due date on or after from_date (default today, Europe/London) and are filtered to to_date; deadlines that depend on your own period (e.g. VAT, Corporation Tax, Companies House) follow with next_due null and a plain-English recurrence_rule. Paid: $0.005 USD per call via x402, or use an API key (see /pricing).
