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.
