Caplia API - Caplia Docs

Caplia has two API surfaces. They share the same hosts but serve opposite sides of the table - pick the one that’s you so you’re reading the right docs.

I'm an investor

Venture API. Read your deal flow, submit and score inbound pitch decks, pull CRI and thesis-fit scores, metrics, and data rooms across your whole pipeline. For VC funds, accelerators, angels, and corp-dev teams.Keys: cap_inv_* · Namespace: /v1/companies, /v1/search, …

I'm a founder

Founder API. See your own company’s CRI score and the rubric’s improvement guidance, and iterate your pitch deck privately until it clears Caplia Verified (CRI ≥ 700). For founders raising on Caplia.Keys: cap_fnd_* · Namespace: /v1/me/*

Not sure which you are?

If you want to…	You want the…
Read and triage other companies’ deals in your pipeline	Venture API
Score inbound decks at scale, or embed an upload form on your site	Venture API
Improve your own company’s score and pitch deck	Founder API
Connect Claude to rewrite your deck until you’re Caplia Verified	Founder API

Both surfaces run on api.venture.caplia.ai and mcp.venture.caplia.ai. Your API key prefix - cap_inv_* or cap_fnd_* - decides which one you get; they’re not interchangeable.

Common to both

REST + MCP. Everything is available as a REST API and as MCP tools for Claude, Cursor, ChatGPT, and other agents.
v1, additive only. All paths are prefixed with /v1. We don’t break v1.
Sandbox for safe testing. A -sandbox host with *_test_* keys mirrors production against isolated data. Cross-environment leaks fail closed.
