Know who just raised, and what to say to them.
ProspectAPIs is a REST API that gives sales teams and their agents fresh funding rounds and a sourced brief on any company, from one key. Every claim carries its source, so nothing you say on a call is a guess.
Per our API reference, a funding search takes 9 filters and returns up to 100 records a page, each with the URL where the round was announced.
Search funding rounds on demand, get new matches pushed to your webhook, and research what to say to them. Your agent can call all three through the MCP server, on npm now.
Venture rounds, debt, grants and IPOs, newest first. Filter by date, round, amount, investor and country.
Save funding filters and a webhook. Each new matching round is pushed to you, signed, as it lands.
One call turns a domain, email, LinkedIn URL or name into a cited brief for account research, a call or outreach.
Every API as tools for MCP clients such as Claude Code and Cursor. Published on npm as prospectapis-mcp (MIT); run it with npx -y prospectapis-mcp.
Submit a prospect, poll by id, and read a brief where every field names the page it came from.

}From the call that starts in five minutes to the outbound list that refreshes every morning.
Send the domain from the calendar invite with purpose pre_call and your product as context. The brief comes back with why they would care, likely objections and discovery questions.
Every statement is tagged fact, interpretation or angle, so a sales suggestion never reads as something the prospect said.
purpose outreach returns what changed at the company and three to five hooks. Each hook is a dated, cited fact, what it suggests, the angle and a draft first line.
No hook without a source, so a message built on them cannot read as templated.
Run the default account_research purpose across a named account list to get company, traction, competitors, news, people, risks and regions for each.
A field the sources do not support is null, never a guess, so a thin account shows up as thin.
Save a watchlist with round, amount and country filters and a webhook. Each new matching round is pushed to you as it lands, so outreach starts the day budgets open.
Each delivery costs one record and is charged only when your webhook answers 2xx.
Look up a domain to attach every round we hold, the lead investors and the announced date to the account in your CRM.
domain is an exact match and investor is a case-insensitive exact name, so the join is predictable.
Install the MCP server (npx -y prospectapis-mcp) and your MCP client searches rounds, starts research briefs and manages watchlists in plain language, with the same key and credits as the REST API.
Five tools write: research_submit spends credits, the watchlist create, test and delete tools change state, and feedback_send reports to the team. Every other tool only reads, so a client can ask before it spends.
Send it to the team from your own code or agent with POST /v1/feedback. It is free, and reports go straight to the people who build the API.
Every endpoint is a tool your MCP client can call. Published on npm as prospectapis-mcp (MIT); run it with npx -y prospectapis-mcp.
Install
Add it to Claude Code with one command, or to any MCP client as npx -y prospectapis-mcp with your API key in PROSPECTAPIS_API_KEY. Setup for each client is on the MCP page.
Pricing
Each tool bills exactly like the API call it makes: funding_search like GET /v1/funding, research_submit like POST /v1/research.
Tools
One tool per endpoint
The same filters, limits and errors as the REST routes they wrap.
Prices in the tool text
Each tool states what it costs, and account_balance reports your balance and prices.
Submit, then poll
research_submit returns an id at once; research_get reads it until completed or failed.
Standard transport
It speaks plain MCP over stdio, so it is not tied to one client.
A brief reads the company's own pages, searches the news and joins our funding table. Then it keeps only what a source states.
Prefer to research an account by hand first? Our guide to sales prospect research lists the nine facts worth finding before a first message, and the blog has more.
What a source states
Always cited, with the URL, title, kind and when it was read.
What the facts suggest
Kept apart from facts so it never reads as something the prospect said.
A suggestion for you
Only with your context, shaped by pre_call, outreach or account_research.
