Cada endpoint retorna dados de conversão de tamanhos para sapatos, anéis, chapéus e roupas, incluindo medidas em várias unidades (mm, cm, in) e etiquetas de tamanho em diferentes sistemas (EUA, Reino Unido, UE, Japão)
Os campos principais incluem "categoria" (tipo de item) "entrada" (tamanho e sistema do usuário) "tamanhos" (tamanhos convertidos em vários sistemas) e "faixa" (variância de tamanho) Cada campo fornece informações essenciais para conversões de tamanhos
Os parâmetros incluem "tamanho" (o tamanho original), "sistema" (o sistema de tamanho utilizado) e para alguns endpoints, "tipo" (por exemplo, mulheres, homens). Os usuários podem especificar esses para personalizar seus pedidos de conversão
A resposta é estruturada com uma categoria principal, detalhes de entrada e um objeto de tamanhos contendo tamanhos convertidos para vários sistemas Cada entrada de tamanho inclui o tamanho, valor, rótulo e faixa para clareza
Os dados são derivados de padrões e fórmulas de tamanho estabelecidos, como ISO para anéis e práticas comuns de dimensionamento para vestuário e calçados. Isso garante consistência e confiabilidade nas conversões
Casos de uso típicos incluem plataformas de e-commerce que precisam de conversões de tamanhos para clientes internacionais, varejistas de moda fornecendo guias de tamanhos e aplicativos ajudando os usuários a encontrar seus tamanhos corretos entre marcas
Os usuários podem utilizar os dados retornados referenciando o objeto "tamanhos" para encontrar tamanhos equivalentes em diferentes sistemas garantindo um ajuste preciso ao comprar itens de várias regiões ou marcas
A precisão dos dados é mantida através da adesão a padrões de dimensionamento e atualizações regulares com base nas práticas da indústria A API também leva em conta as variações de marcas para refletir as discrepâncias de dimensionamento do mundo real
