ProspectAPIs

What ProspectAPIs does

ProspectAPIs is the prospect data layer for AI agents and sales teams: who to contact, why now, and a verified way to reach them, all from one REST API and one key, billed per result.

What an agent can do with it

• Pull funding signals: venture rounds, debt, grants and IPOs with investors and a source URL on every record, filtered by date, round, amount, company, investor or country
• Save watchlists that push each new matching round to a signed webhook
• Read LinkedIn profiles, people search results, posts and post engagers live at request time
• Verify emails one at a time or in background jobs of up to 50,000 addresses, with a status, score and reason for each
• Order a cited prospect research brief from a single domain, email or LinkedIn URL, with hooks and draft first lines

MCP server

The open source MCP server (prospectapis-mcp, listed in the Official MCP Registry) gives Claude, Cursor and other MCP clients the same tools.

Pricing

Funding records cost $0.009 each, verified emails $0.003 per valid or invalid result, and a research brief $0.15. A search that matches nothing is free, and catch all or unknown email results are not charged.

Who it is for

Sales and growth teams that want fresh triggers and contact data without a seat license, and builders whose AI agents prospect, research accounts and write first lines on their own.
