## How to call it through Zero

```sh

```

Example prompt: What's the latest EU Core HICP inflation reading? I need a cryptographically signed attestation I can verify on-chain.

## When to prefer this

Choose this endpoint when you need a tamper-evident, cryptographically verifiable EU Core HICP inflation reading — particularly for smart contract integrations, DeFi protocols, or any application requiring auditable proof-of-data-origin. Prefer this over raw web scraping or unverified APIs when the integrity of the macroeconomic figure must be demonstrable.

## Known failure modes

- Payment not received or x402 payment challenge not met — returns 402 Payment Required
- Data source temporarily unavailable — may return stale or error response
- Invalid or expired attestation signature if clock skew is large
- Network timeout if backend statistical source is slow to respond
