Request

Endpoint: GET https://api.outscraper.cloud/contacts-and-leads

Parameters

NameInTypeRequiredDescriptionExampleConstraints
query query array<string> Yes Domain or link (e.g., outscraper.com). It supports batching by sending arrays with up to 1000 queries (e.g., query=text1&query=text2&query=text3). It allows multiple queries to be sent in one request and to save on network latency time. - -
preferredContacts query array<string enum> No Preferred contacts. It supports multiple categories (e.g., preferredContacts=technical&preferredContacts=influencers). - -
contactsPerCompany query integer No The parameter specifies the number of Contacts per one company. - default 3
emailsPerContact query integer No The parameter specifies the number of email addresses per one contact. - default 1
skipContacts query integer No The parameter specifies the number of contacts to skip. Used for pagination. - default 3
generalEmails query boolean No The parameter specifies whether to include only general email (info@, support@, etc.) or only not general email (paul@, john@, etc.). - default
fields query string No The parameter defines which fields you want to include with each item returned in the response. By default, it returns all fields. Use &fields=query,name to return only the specific ones. - -
async query boolean Yes The parameter defines the way you want to submit your task to Outscraper. It can be set to false to open an HTTP connection and keep it open until you got your results, or true (default) to just submit your requests to Outscraper and retrieve them later (usually within 1-3 minutes) with the Request Results endpoint. Each response is available for 4 hours after a request has been completed. A good practice is to send async requests and start checking the results after the estimated execution time. Check out this Python implementation as an example. As most of the requests take some time to be executed the async=true option is preferred to avoid HTTP requests timeouts. - default true
ui query boolean No The parameter defines whether a task will be executed as a UI task. This is commonly used when you want to create a regular platform task with API. Using this parameter overwrites the async parameter to true. - default false
format query array<string enum> No The parameter defines the format of the output data. Using this parameter overwrites the ui parameter to true. - -
webhook query string No The parameter defines the URL address (callback) to which Outscraper will create a POST request with a JSON body once a task/request is finished. Using this parameter overwrites the webhook from integrations. - -
