Every signal links to the filing it came from.
Fundz is a buying signals API and MCP server for sales agents: dated funding rounds and SEC 8-K events, each one carrying the source document. It is a company event API rather than a contact database — the trigger data for AI SDRs that tells an agent why now, with a link a human can open before anything gets sent.
Two lanes, both primary-filed:
sec.gov.Nothing is inferred. If Fundz has no dated event for a company in your window, it says so instead of guessing — an empty answer is a real answer, and it is the reason the evidence is quotable.
Dated evidence with a source URL on every item, the resolved company, and a
resolution_confidence score so you can refuse to act on an uncertain match. Usage comes back in
X-Fundz-Units headers on every response.
No contacts. No emails. No phone numbers. Fundz answers which companies just did something worth calling about, not who to call. Pair it with your own contact source.
It is also not a prediction product. predicted_next is explicitly experimental — treat lift as
a ranking aid, not a validated rate.

Streamable HTTP at https://api.fundz.net/v1/agent/mcp. initialize and tools/list need no
key; tools/call does.
⛔ That is a subpath, not the REST prefix. /v1/agent reads its last path segment as a tool name,
so an MCP handshake posted there is answered 404 unknown tool 'agent'.

An API that returns events — a company raised money, filed an 8-K, changed leadership — rather than static firmographics. The event is the reason to reach out, and the date is what makes it timely. Fundz returns the event plus the document it came from.
Those are databases you search. This is an API an agent calls per company, per run, and every item comes back with a source URL. Fundz is also priced per unit rather than per seat.
No. Fundz has no contacts, emails, or phone numbers. It tells you which companies just did something; you bring your own contact source.
Form D private-offering filings parsed from EDGAR — filing entity, offering amount normalised to
USD, state, and a sec.gov source URL per record — alongside funding announcements from news.
Yes. Every 8-K item carries the sec.gov document URL. That is the point: a rep can open the
filing before quoting it to a prospect.
Call watchlist_diff with your account book on a schedule and act only on companies that come
back changed. It bills 0.1 units per company checked, so a 400-company book costs 40 units — the
same whether you send it whole or in chunks.
Yes — this one. Streamable HTTP, four tools, works in Claude Desktop, Cursor, and any client that
speaks MCP over HTTP. Discovery (initialize, tools/list) is keyless so a client can inspect it
before you hand over a credential.
You get an empty evidence array and a last_event telling you when the most recent one actually
was. Fundz does not manufacture a reason to call.
400 domains per request. The limit is the edge, not the API: bodies over 8,192 bytes are refused before they reach us.
