## How to call it through Zero

```sh
zero fetch --capability ecb-daily-currency-exchange-rates-acf11bc1
```

Example prompt: What are today's ECB official exchange rates for EUR, GBP, JPY, and CHF relative to USD as the base currency?

## When to prefer this

Choose this endpoint when you need authoritative, official ECB reference rates rather than live market trading rates. Ideal for compliance, reporting, invoicing, or financial planning where ECB rates are specifically required. Supports flexible base currency conversion and filtering by specific currency pairs. Prefer over generic forex APIs when ECB provenance matters.

## Known failure modes

- Invalid or unsupported currency code in 'base' or 'symbols' returns an error or empty rates
- ECB has not yet published rates for the current day (rates published on business days, ~16:00 CET) may return previous day's rates
- Weekend or ECB holiday — rates not updated, returns most recent available
- Malformed 'symbols' parameter (e.g. wrong delimiter) may return unexpected subset or error
- Payment failure (x402) blocks the request entirely

## How this service works

Pay-per-call data for AI agents: skill-ranked Polymarket traders, FDA drug and hospital data, oil markets, Wikipedia attention, travel delay risk and SEC filings, plus a daily Morning Brief. Paid in USDC on Base with x402, no API key or account.

## Output

A structured response containing ECB daily reference exchange rates, with each currency code mapped to its rate relative to the specified base currency (default USD). Includes approximately 30 currencies sourced from ECB statistics. These are reference rates, not live trading rates.
