The Caplia API gives external tools - CRMs, Slack apps, scheduled scripts, MCP clients - programmatic access to the rich data surface inside Caplia: companies, CRI and thesis-fit scores, traction metrics, data room documents, theses, and pipeline views.

​
What you can do

Read your pipeline

List companies in any of your pipeline views, fetch a company profile, pull its CRI score, thesis matches, traction metrics, and data room contents.

Push deals in

Send pitch decks from anywhere - they flow into the same intake pipeline as your web uploads and email forwards, auto-extracted and scored on arrival.

Poll for results

The deck upload is async. Poll the jobs endpoint to watch the company appear, then the CRI score, then the thesis matches - surface partial results to your users as they land.

Use it from AI agents

A Model Context Protocol (MCP) server at mcp.venture.caplia.ai lets Claude Desktop, Cursor, Windsurf, and other MCP-aware clients call Caplia tools directly.

Embed a deck-upload form

Drop the Venture Form Widget into your Webflow, WordPress, or HTML site to push pitch decks straight to Caplia from a public form — no API key in the browser. Built for VC inbound, accelerators, awards, and corp-dev intakes.

Cross-environment leaks fail closed: a live key hitting a -sandbox URL returns 401, and a test key hitting a production URL returns 401. Same code on both — only the data and the accepting key prefix differ.
