## 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 synthora-ecb-macro-d74c563c -d '<json body>'
```

Example prompt: Can you pull the latest ECB macro snapshot — HICP inflation, the MRR policy rate, and the 10-year eurozone government yield — and tell me which ones have moved and in what direction since last period?

## When to prefer this

Choose this endpoint when you need official, authoritative ECB-sourced eurozone macro data (HICP inflation, MRR rate, 10Y yield) with change and direction metadata in a single call, without managing ECB API keys or parsing the ECB Data Warehouse directly. Ideal for macro/rates agents, prediction markets, and dashboards that require a low-latency, structured snapshot of the three core eurozone indicators.

## Known failure modes

- ECB Data Warehouse unavailable or returning stale data — endpoint may return cached or error response
- Upstream ECB API rate limits or maintenance windows causing request failures
- Malformed response if ECB changes data schema without endpoint update
- Payment failure via x402 protocol causing 402 rejection before data is returned
