## 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 euro-memoryapi-org-7e359d4f
```

Example prompt: What's the latest M3 money supply figure for the Euro Area from the ECB, and can you also pull the most recent TARGET2 interbank balance data?

## When to prefer this

Choose this endpoint when you need authoritative ECB-sourced monetary data specifically for the Euro Area — M3 money supply aggregates or TARGET2 interbank balances. Prefer this over general economic statistics APIs when the focus is on monetary aggregates or central bank settlement data rather than GDP, inflation, or trade figures (use sibling endpoints for those).

## Known failure modes

- Requested time period out of available data range — returns empty or error response
- Invalid data type parameter (not M3 or TARGET2) — returns 400 bad request
- ECB data source temporarily unavailable — returns 503 or timeout
- Payment not processed (x402 protocol failure) — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests

## How this service works
