Localecheck
Overview
localecheck gives AI agents verified, authoritative answers to the "boring" international data that LLMs routinely hallucinate — and flags impossible inputs instead of guessing. Coverage: UK + USA (v1). Free, no API key.
Agents are systematically wrong outside US-English defaults: they read 03/04 as March 4 in the UK, apply today's VAT rate to a historical invoice, format €1,234.50 for a German reader, and miss bank holidays when computing delivery SLAs. localecheck replaces guesses with checked answers.
Tools
- parse_date — ambiguous date → ISO 8601, locale-aware (en-GB day-first vs en-US month-first); flags impossible dates.
- validate_phone — → E.164 + line type, via libphonenumber.
- format_currency — locale-correct currency string, via CLDR.
- tax_rate — UK standard VAT for a given date (handles historical/temporary changes); US national 0 + state base sales tax.
- is_holiday / next_holiday — public/bank-holiday checks (GB defaults to England; subdivisions supported).
- parse_address — UK/US address → {country, postcode, city} with a confidence flag.
