## 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 fx-rate-ecb-currency-exchange-rate-cdbc93b0
```

Example prompt: What's the official ECB reference exchange rate from USD to EUR today?

## When to prefer this

Choose this endpoint when you need an authoritative, official exchange rate backed by the European Central Bank — ideal for compliance, accounting, invoicing, or any scenario requiring a benchmark rather than a live market price. Prefer this over crypto price feeds or live interbank rates when regulatory or audit-grade FX data is needed.

## Known failure modes

- Unsupported currency pair returns an error — ECB only covers major currencies
- Weekend or holiday dates may return the most recent available rate rather than exact date
- Missing or malformed currency code parameters result in a 400 bad request
- Network latency from Cloudflare Workers edge may vary; ECB data updates once per business day

## How this service works

Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
