The Founder API gives founders programmatic access to their own company on Caplia: your CRI score and its per-domain breakdown, the rubric’s concrete improvement recommendations, your traction metrics, your data room, and a private deck-scoring loop that lets an AI agent rewrite your pitch deck until it clears Caplia Verified (CRI ≥ 700) - all without an investor ever seeing the score thrash along the way.
Live. The Founder API is available in production (api.venture.caplia.ai, mcp.venture.caplia.ai), with a sandbox (api-sandbox.venture.caplia.ai, mcp-sandbox.venture.caplia.ai) for safe testing. Mint a company-scoped key in the founder portal - see Authentication.
Founder, not investor? This is the right place. If you’re a VC, accelerator, angel, or corp-dev team reading other people’s deal flow, you want the Venture API instead. The two are separate surfaces with separate keys.

What you can do

See your CRI and what to fix

Pull your live CRI score (0-1000), its six domain breakdowns, and the rubric’s ranked, concrete recommendations - the same signals investors see, plus exactly how far you are from Caplia Verified.

Iterate your deck to 700

Submit a deck draft, get a private CRI score back, regenerate, resubmit - loop until you clear 700, then publish one clean public update. Investors never see the drafts.

Keep your profile current

Update your company name, website, industry, stage, and problem statement, and upload documents to your data room - so the record investors read stays accurate.

Drive it from Claude

Connect Claude (or any MCP client) to the Caplia MCP server and run the whole loop in natural language - pair it with Canva or your deck tool and let the agent rebuild the deck between scores.

​
How the Founder API is different

The Founder API and the Venture API run on the same hosts (api.venture.caplia.ai, mcp.venture.caplia.ai) but behave differently depending on which kind of key you present: A founder key is locked to your company. Every /v1/me/* endpoint resolves the company from the key itself, so there’s no company id to pass and no way to read or change anyone else’s data.

Environments

Cross-environment leaks fail closed: a live key hitting a -sandbox URL returns 401, and a test key hitting a production URL returns 401.
