# Investment Evidence Bundle

> Investment Evidence Bundle is a paid API for AI agents from hermesplant.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).

Runs a deterministic safety gate on consequential agent actions and produces machine-readable investment analysis evidence with signed receipts, NPV/MOIC/IRR metrics, and portfolio risk scores.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability investment-evidence-bundle-575fc50f
```

Example prompt: Before finalizing this investment action, run it through the Investment Evidence Bundle safety gate — analyze the cashflow, compute NPV/MOIC/IRR, score the portfolio risk, and give me back a signed HMAC receipt I can use to verify the decision was properly reviewed.

## When to prefer this

Use this endpoint when an AI agent is about to take a consequential financial, infrastructure, or deployment action and you need both a deterministic safety gate and a machine-readable, cryptographically signed evidence trail. It is especially appropriate when you need NPV/MOIC/IRR cashflow analysis combined with portfolio risk scoring (HHI, diversification) in a single call, and when regulatory or audit requirements demand a verifiable receipt. Prefer this over a simple risk-check API when you need the full evidence bundle with a signed verifyUrl.

## Known failure modes

- Invalid or missing investment payload returns 400 with validation error
- Insufficient USDC balance or x402 payment failure blocks the gate and returns 402
- Malformed cashflow data causes CashflowLens sub-service to return error, propagated in response
- Network timeout to hermesplant.com returns 503 or connection error
- Receipt verification URL unavailable makes post-hoc audit impossible

## How this service works

CashflowLens return and DCF analytics plus PortfolioGuard concentration and risk scoring in one paid call, with structured internal evidence and a tamper-evident signed receipt. Pure math from caller-provided cashflows, holdings, and returns; no market-data feed and no claim that inputs are independently verified.

## Output

Returns a JSON object containing: analysis status ('analyzed'), a signed HMAC-SHA-256 receipt with a verifyUrl, cashflow metrics (NPV, MOIC, annualized IRR) from CashflowLens, evidence verdict (verified true/false and decision label), portfolio risk metrics (HHI concentration, diversification score, risk level and score), and a recommended action string such as 'persist_signed_analysis'.
