URL

Aprenda como raspar qualquer página da Grainger submetendo sua URL usando a fonte grainger com a Web Scraper API.

Você pode obter resultados do Grainger fornecendo suas próprias URLs para nosso grainger source.

Amostras de requisição

Nos exemplos abaixo, fazemos uma solicitação para recuperar uma URL de exemplo do Costco.
