## 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 delx-gross-margin-31edc316 -d '<json body>'
```

Example prompt: What's the gross margin and gross profit if my product costs $42.50 to make and I'm selling it for $79.99?

## When to prefer this

Use this endpoint when you need a fast, cheap, deterministic gross margin calculation as a preflight or analysis step inside an agent workflow — especially when you want stateless, local-only computation with no data retention. Prefer this over general-purpose LLM math when you need machine-readable JSON output, consistent precision, and a guaranteed formula rather than an approximated answer.

## Known failure modes

- Missing required field (cost or price) returns a validation error
- Non-numeric values for cost or price return a type error
- Price of zero may cause division-by-zero handling in margin calculation
- Negative cost or price values may return unexpected or undefined results

## How this service works

Calculate gross profit, gross margin, and profitability. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production co…

## Output

Returns a deterministic JSON object containing gross profit (price minus cost), gross margin percentage, and profitability indicators — all computed locally with no external calls or data retention.
