Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 datanexusai-ecb-monetary-policy-stance-d296d71a
```

Example prompt: What is the ECB's current liquidity stance — is it balanced, tight, or loose — and what's the corridor width between their key rates right now?

## When to prefer this

Choose this endpoint when you need a pre-computed, classified summary of ECB monetary policy stance rather than raw ECB rate data. It is ideal for agents that need a single structured signal (balanced/tight/loose) plus quantitative corridor metrics without performing their own rate arithmetic. Prefer it over raw central bank data feeds when you want derived analytics delivered as a low-cost micropayment API call.

## Known failure modes

- Payment failure: if USDC micropayment via x402 is not completed, the request is rejected with HTTP 402
- Data unavailability: if ECB rate data sources are temporarily unavailable, the endpoint may return an error or stale indicator
- Rate limit exceeded: excessive calls may result in HTTP 429
- Malformed request: non-GET methods return HTTP 405

## How this service works

Public data API for SEBRA payments, PTP road accidents, Hearthstone cards, EU agri-food prices, and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). Docs and discovery endpoints are free.

Machine-readable discovery: `https://api.datanexusai.org/openapi.json`, `https://api.datanexusai.org/llms.txt`, `https://api.datanexusai.org/.well-known/x402`.

Human docs: `/docs` and `/api/`.

## Output

A JSON object with a 'derived' block containing: 'liquidity_stance' (a string classification such as 'balanced', 'tight', or 'loose'), 'corridor_width_pp' (the ECB interest rate corridor width in percentage points), and 'estr_minus_dfr_pp' (the spread between ESTR and the ECB deposit facility rate in percentage points). Also includes an 'endpoint' identifier string confirming the data source.
