FREE, unmetered. GET /v1/calendar for this brand's continent. Optional country (ISO 3166-1 alpha-2) and series. Derives reverify_by from last_confirmed + update_cycle_days (the same window that sets stale) and, only when current.effective_to is a non-empty string, next_effective_known with basis effective_to. status unknown omits that date. Never parses notes. Does not invent MPC, budget, or wage-review dates. next_effective_known is the recorded end of the current value, not a promised gazette event. A 402 is a gate bug — do not pay. Past changes stay on get_changes.

PAID ($0.02). One series (e.g. vat, policy-rate, minimum-wage, corporate-tax) across up to 10 countries of this brand in one call; each row carries its own source, dates and labels, and countries without the series are listed under missing. Malformed requests are refused free. Pass api_key if you have one; otherwise the response explains how to pay via x402. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.05) on this series so a later gazette does not silently retire the value.
PAID ($0.01). Country brief: every reference series we hold for one country (policy rate, VAT/GST, CPI, taxes, minimum wage, holidays...) in one call, each with value, unit, effective and last-confirmed dates, official source and confidence label. Cheaper than buying the series one by one. Pass api_key if you have one (card checkout at /pricing); otherwise the response explains how to pay via x402. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.05) on this series so a later gazette does not silently retire the value.
PAID ($0.003). Offline format and check-digit validation of a business tax ID or VAT number for one country of this brand: valid/invalid, normalised form, id type, check level (checksum only where the authority publishes the algorithm) and why it failed, with official sources. Does not confirm registration; follow official_lookup for that. Countries without a sourced rule answer free with status 'unknown'.

The start date is day 0 and never counted; n = 0 returns the date itself if it is a business day, otherwise the next one. Lists every non-business day skipped and why. Uses the country's national public-holiday calendar and its statutory weekend rule (Gulf Friday+Saturday, Israel Saturday-only, India 2nd/4th Saturdays, Nepal's 2026 change, China's multi-day breaks and make-up working days). A date in a year whose holidays we do not hold is refused with error year_not_held and the years_held list; it is …

Where a rule's source does not say which way a weekend deadline moves, the date is flagged roll_unverified rather than guessed. Countries or taxes we could not ve…
