Tools (8)

`calculate_employer_ni`read-only	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).
`check_uk_business`read-only	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).
`get_rate`read-only	Get the UK rate/threshold in force for a key on a date (default today, Europe/London). Returns value, unit, effective dates and source. Paid: $0.005 USD per call via x402, or use an API key (see /pricing).
`get_rate_history`read-only	Get every version of a rule, ordered by applies_from. Paid: $0.005 USD per call via x402, or use an API key (see /pricing).
`list_deadlines`read-only	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).
`list_topics`read-only	List rule topics (e.g. income_tax, vat) with the number of rules in each.
`search_rules`read-only	Free. Finds rule keys. Use get_rate (paid) to get the value in force on a date.
`search_uk_company`read-only	Search Companies House for UK companies by name. Free. Returns up to 10 matches (name, company number, status, incorporation date) so you can pick the right company_number for check_uk_business.
