How nip24pl/nip24-php-client works

NIP24 Client for PHP combines local Polish/EU identifier validators with authenticated online company and tax-data lookups. A caller invokes the client API, which sends HTTP requests to NIP24 and parses responses into result models; the library also exposes validation, account, invoice, registry, VAT/VIES, whitelist, and IBAN capabilities. The sampled code confirms request/response handling and serializer behavior, but does not show every endpoint method, so those capability branches are grouped at the client level.
