How To Remove Unwanted Data Like CreatedAt, UpdatedAt, CreatedBy from the API response

Hey @guilheermeff if you want top remove that data you can customize the controller or services by using entity services from strapi

/**
 * contact-us service
 */

module.exports = {
    getContactUsData: async () => {
      try {
  
        const entries = await strapi.entityService.findMany(
          "api::contact-us.contact-us",
          {
            fields: ['id'],
            populate: {
              hero: {
                fields: ['title'],
                populate: {
                    image: {
                        fields: ['url', 'alternativeText','width', 'height'],
                    }
                }
              },
              contact: {
                fields: ['title', 'description'],
                populate:  {
                    form: {
                        fields: ['*'],
                    },
                    button: {
                        fields: ['title', 'href', 'target'],
                    },
                }
              },
              address: {
                fields: ['address', 'email', 'phone']
              }
            }
          }
        );
  
        return entries;
      } catch (err) {
        return err;
      }
    },
  };
