## 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 milestone-refund-calculator-mcp-e4b86a3e -d '<json body>'
```

Example prompt: Calculate the refund amount for a project where 3 out of 5 milestones were completed, total contract value was $5,000, and the client is cancelling the remaining work.

## When to prefer this

Use this endpoint when you need to programmatically compute refund amounts tied to milestone-based contracts or project deliverables, especially in freelance, construction, SaaS, or subscription contexts where partial work completion must be fairly valued and refunded.

## Known failure modes

- Missing or malformed data field returns a validation error
- Ambiguous milestone completion percentages may produce inaccurate results
- Incomplete contract value information may cause computation failure
- Edge cases like 0% or 100% completion may return unexpected outputs if not handled
