# ECB Currency Converter

> ECB Currency Converter is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

## 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 api-x402node-dev-7f4cfd9b
```

Example prompt: Can you convert 100 USD to EUR at the current ECB rate and tell me the exact rate and date it's from?

## When to prefer this

Choose this endpoint when you need a reliable, ECB-sourced exchange rate for financial quoting or price display across currencies, especially for EUR-adjacent pairs. Prefer it over scraping or general-purpose APIs when you need a trusted institutional rate with a known date stamp and minimal latency for agent workflows.

## Known failure modes

- Unsupported or invalid currency codes (e.g. non-ISO 4217 codes) may return an error
- Amount parameter missing or non-numeric causes a bad request response
- ECB rate data temporarily unavailable causes a service error
- Rate may be from previous business day if ECB hasn't published today's rate yet
- Payment failure ($0.005 USDC) blocks the request entirely
