# Founder API

> See your CRI score, read the rubric's improvement guidance, and iterate your pitch deck to Caplia Verified - programmatically, for your own company.

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.

<Note>
  **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/authentication).
</Note>

<Info>
  **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](/quickstart) instead. The two are separate surfaces with separate keys.

## What you can do

<Columns cols={2}>
  <Card title="See your CRI and what to fix" icon="gauge-high" href="/founder/quickstart">
    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.
  </Card>

  <Card title="Iterate your deck to 700" icon="arrows-rotate" href="/founder/deck-loop">
    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.
  </Card>

  <Card title="Keep your profile current" icon="pen-to-square" href="/founder/api-reference/introduction">
    Update your company name, website, industry, stage, and problem statement, and upload documents to your data room - so the record investors read stays accurate.
  </Card>

  <Card title="Drive it from Claude" icon="plug" href="/founder/mcp">
    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](/quickstart) run on the **same hosts** (`api.venture.caplia.ai`, `mcp.venture.caplia.ai`) but behave differently depending on which kind of key you present:

|                             | Founder API                                          | Venture API                             |
| --------------------------- | ---------------------------------------------------- | --------------------------------------- |
| Who it's for                | A founder, on their own company                      | Investors reading their deal flow       |
| Key prefix                  | `cap_fnd_live_*` / `cap_fnd_test_*`                  | `cap_inv_live_*` / `cap_inv_test_*`     |
| Scope                       | **One company** - the company the key was minted for | The caller's whole pipeline             |
| How a company is identified | Resolved from the key - no company id in any request | By id, in the path                      |
| Namespace                   | `/v1/me/*`                                           | `/v1/companies/*`, `/v1/search`, etc.   |
| Headline feature            | Private deck-scoring loop → Caplia Verified          | Submit and score inbound decks at scale |

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.

## Base URL

```
https://api.venture.caplia.ai/v1
```

## Environments

|            | Production                             | Sandbox                                        |
| ---------- | -------------------------------------- | ---------------------------------------------- |
| REST       | `https://api.venture.caplia.ai/v1/...` | `https://api-sandbox.venture.caplia.ai/v1/...` |
| MCP        | `https://mcp.venture.caplia.ai/`       | `https://mcp-sandbox.venture.caplia.ai/`       |
| Key prefix | `cap_fnd_live_*`                       | `cap_fnd_test_*`                               |
| Data       | Your real company                      | Sandbox / test company                         |

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