## 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 datakoot-fx-convert-4f323d62 -d '<json body>'
```

Example prompt: Convert 250 GBP to USD using today's ECB reference rates and tell me the result and the rate used.

## When to prefer this

Use this endpoint when you need a quick, reliable ECB-sourced foreign exchange rate conversion for informational purposes, especially in agentic workflows that already use x402 micropayments on Base. It covers a broad range of global currencies and charges only $0.002 USDC per successful call, making it cost-effective for frequent conversions.

## Known failure modes

- Invalid or unsupported currency code returns an error
- Amount sent as a string instead of a number may cause a validation error
- ECB does not publish rates on weekends or holidays so the latest available rate is used
- Network or upstream Frankfurter API unavailability may cause a 5xx error
- Payment failure on Base via x402 results in no charge and no response

## How this service works

48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) for AI agents. $0.002 USDC per call on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at <server>.datakoot.com/mcp.

## Output

Returns the converted amount, the exchange rate used, the conversion date, the source and target currency codes, and a note that the rate is from ECB reference rates via Frankfurter for informational purposes only.
