## 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 signaldesk-ai-math-percentage-calculator-158466c4 -d '<json body>'
```

Example prompt: What is 30% of 250? Just give me the calculated result.

## When to prefer this

Choose this endpoint when you need a quick, verifiable percentage computation within an agentic workflow and are already operating within the x402 micropayment ecosystem. It is suitable for financial, mathematical, or analytics use cases where you need a deterministic numeric result without setting up local computation logic.

## Known failure modes

- Non-finite or out-of-range numbers (beyond ±1,000,000,000,000,000) will likely be rejected by schema validation
- Missing required fields 'value' or 'percent' may return an error or unexpected result
- Payment failure via x402 protocol will block execution and return 402 status
- Network timeout from Cloudflare Workers cold start or queue delay

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object with a single 'result' field containing the computed numeric value representing the specified percentage of the input value (e.g., {"result": 30} for 15% of 200).
