## How to call it through Zero

```sh
zero fetch --capability gocreative-roman-numeral-converter-9bb197ef
```

Example prompt: What's 2024 written in Roman numerals?

## When to prefer this

Use this endpoint when an agent needs a quick, reliable, pay-per-call Roman numeral conversion without setting up an API key or signing up for a service. Ideal for one-off conversions inside an agentic workflow that already handles x402 micropayments in USDC on Base.

## Known failure modes

- Non-integer or non-numeric input may return an error or unexpected result
- Numbers outside the valid Roman numeral range (typically 1–3999) may fail or return an error
- Missing or malformed {arg} path parameter returns a 4xx error
- Payment failure via x402 prevents the call from completing

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns a JSON object with the original integer input, the computed Roman numeral string (e.g. 'XLII' for 42), and a source field indicating the value was computed server-side.
