## 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-rates-d9cab7e6 -d '<json body>'
```

Example prompt: What are today's ECB reference exchange rates for EUR, GBP, and JPY against USD?

## When to prefer this

Use this endpoint when you need real-time ECB reference FX rates for one or many currency pairs in a single call, particularly when you want a pay-per-use model (no subscription) and are already operating in a crypto-native or x402-compatible payment environment. Prefer it over subscription FX APIs when usage is sporadic or when you need a broad basket of currencies cheaply. Not suitable for live transaction benchmarking or high-frequency trading where tick-level accuracy is required.

## Known failure modes

- Invalid 3-letter currency code returns an error or empty rates object
- Unsupported or misspelled currency symbol in the symbols field may be silently omitted or return an error
- ECB reference rates are only updated on business days — weekend/holiday queries return the most recent available date
- Network or upstream Frankfurter outage returns a 5xx error
- Payment failure via x402 means the call is not charged and no data is returned

## 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

A JSON object containing the base currency, the date of the rates, and a map of target currency codes to their exchange rates (e.g. {"base":"USD","date":"2026-10-02","rates":{"EUR":0.89087,"GBP":0.75753,"JPY":157.67}}). Rates are ECB reference rates sourced via Frankfurter and are for informational purposes only, not transaction benchmarks.
