Find email addresses or phone numbers with a highly reliable API.
The SignalHire API allows developers to integrate the capabilities of SignalHire into their own applications. It provides access to a wealth of contact information, including emails, phone numbers, and social media profiles, from a global database of professionals. The API enables businesses to find and verify contact details, improve customer outreach, and enrich data for CRM systems.
SignalHire API is designed to be simple, scalable, and secure. It offers a variety of endpoints to retrieve detailed information about individuals, companies, and more. The flexibility of the API allows for easy integration into your existing applications and workflows, giving you access to accurate data when you need it.
Below are two endpoints available in the SignalHire API:
The Person API allows you to retrieve full and detailed information about a specific individual, based on unique identifiers. The search parameters are designed to unambiguously identify a person, as they can include LinkedIn profile links, email addresses, phone numbers, or ID. Once a match is found, the API returns the most comprehensive profile, including not only the individual's personal data such as location, work experience, education, skills, but also complete contact details.
The Search API allows you to search for individuals or companies in the SignalHire database using a wide variety of filters. This API can return multiple results depending on the search criteria provided, such as job title, location, or industry. It is highly useful for lead generation, market research, and talent acquisition.
Unlike the Person API, the Search API returns brief overview of the information about individuals without contact information. The purpose of this API is to enable you to search a large number of potential candidates or prospects and refine your results with filters.
To access the SignalHire API, you need to authenticate using an API key. The API key serves as your unique identifier and ensures that only authorized requests are processed.
The HTTP response headers provide important information about the status of your request and remaining credits. You can find the total remaining credits in the X-Credits-Left header. Alternatively, you can use a special API method to check your remaining credits.
SignalHire API returns various HTTP status codes to indicate the success or failure of your request. Below is a list of the most common response codes:
