## 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 numora-financial-roi-calculator-6ff50203 -d '<json body>'
```

Example prompt: Calculate the ROI for an investment where I spent $1,200 and got back $1,800 in gains.

## When to prefer this

Use this endpoint when you need a simple, serverless, dependency-free ROI computation from a raw cost and gain figure. Ideal for AI agents performing financial analysis, investment evaluation, or business metric reporting where accuracy and speed matter more than complex portfolio-level calculations.

## Known failure modes

- Missing required field 'cost' returns validation error
- Missing required field 'gain' returns validation error
- Non-numeric values for cost or gain cause parse errors
- Cost of zero may cause division-by-zero error
- Payment failure if x402 micropayment of 0.1 USDC is not properly handled
