French companies from the State's Recherche d'entreprises API - the one behind annuaire-entreprises.data.gouv.fr: INSEE's Sirene and INPI's national register (RNE), free, no key, about seven calls a second. For glitchr/omnistate.

$company = (new AnnuaireEntreprises($httpClient))->company('901821074');   // or a SIRET
$company->name, $company->legalForm, $company->status, $company->activity, $company->category,
$company->headcount, $company->headOffice, $company->establishments, $company->managers,
$company->finances, $company->labels /* ess, rge, qualiopi... */, $company->collectiveAgreements,
$company->vatNumber /* from its SIREN */, $company->raw /* the whole answer */;

Too many calls throw UnavailableException with the Retry-After the API gave.
