About

Easily search millions of clients and companies. Use our extensive range of filters to zero in on your audience. Gather prospects with verified contact details from a rich database that is always updating. Segment audiences and export them to specific campaigns. Our lightning-fast database uses multiple sources to ensure that information is accurate. We verify all email addresses before your campaign begins. An extensive range of filters allows you to drill down to your ideal prospects, connecting you with the people who matter. Exclude prospects at company or domain level, to exclude people who have asked not to be contacted and avoid current customers. Segment different cohorts to maximize outreach and test messaging. Upload your own custom audiences. Create multiple templates for initial outreach and follow up emails, before assigning them to campaigns.

About

ProspectAPIs is a hosted REST API and Model Context Protocol (MCP) server for sales teams, outbound teams, founders and developers building prospecting workflows or AI agents. It provides searchable company funding rounds with announcement-source URLs, filters for round, date, amount, company, investor and country, plus signed webhook watchlists for new matching rounds. Its prospect-research endpoint returns a sourced brief about a company or person for account research, call preparation or outreach. The service also includes email verification and related email-data endpoints. MCP clients can call the API tools using the same key and prepaid balance. Funding records cost $0.02 each, completed research briefs $0.15, and customers start with a one-time $1 balance; pricing is prepaid per result rather than per seat or subscription.
