## How to call it through Zero

```sh
zero fetch --capability scriptmasterlabs-fx-currency-converter-9ccb89cd
```

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call FX conversion without committing to a subscription, especially within x402-compatible agent pipelines. It is well-suited for low-volume or sporadic conversion needs where per-call micropayment pricing (0.001 USDC) is more cost-effective than a monthly API plan. Prefer alternatives with higher crawl quality scores or verified exchange rate providers for high-stakes financial applications.

## Known failure modes

- Invalid or unsupported currency codes (e.g. non-ISO 4217 codes) may return an error
- Missing required query parameters (from, to, amount) result in a 400-style error
- Non-positive or non-numeric amount values may be rejected
- Payment failure via x402 protocol results in 402 response before conversion is performed
- Network or upstream FX data feed outages may cause intermittent failures

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

Returns a JSON object containing the source currency code, target currency code, original amount, converted amount (as a decimal string), and a status field indicating success. Example: {"from":"USD","to":"EUR","amount":"100","converted":"85.25","status":"ready","product":"SML FX Convert"}.
