## 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 return-on-average-assets-single-calculation-ec848bdc -d '<json body>'
```

Example prompt: Can you calculate the return on average assets for a company with net income of $4,500,000 and average total assets of $60,000,000? I want the formula, units, and any limitations noted.

## When to prefer this

Choose this endpoint when you need a fast, deterministic single-record ROAA calculation with the formula and units explicitly returned — ideal for spot checks, agent pipelines, or embedding in a financial reporting workflow. Prefer this over batch or distribution endpoints when you have exactly one observation to evaluate and want a structured JSON result with methodology documentation included.

## Known failure modes

- average_assets must be greater than zero (exclusiveMinimum enforced); zero value returns validation error
- net_income or average_assets exceeding ±1,000,000,000,000 will be rejected out of bounds
- Missing required fields (net_income or average_assets) return a schema validation error
- Non-numeric input types cause a type validation failure
- Payment of 0.01 USDC not received or declined results in 402 Payment Required
