## 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 ecb-key-interest-rates-str-db75f245 -d '<json body>'
```

Example prompt: What are the current ECB key interest rates — deposit facility, main refinancing, and marginal lending — and can you show me the last 12 changes to the deposit rate in basis points?

## When to prefer this

Use this endpoint when you need official, up-to-date ECB policy rates and recent rate-change history in a single call. It is preferable to scraping ECB's website or using general financial data APIs when you specifically need all three ECB key rates plus €STR and a structured basis-point history of deposit rate decisions.

## Known failure modes

- ECB Data Portal temporarily unavailable — upstream data fetch fails
- historial parameter out of range (must be 1–40) — may return error or default
- No data if ECB has not updated rates recently
- Network timeout if upstream ECB portal is slow

## How this service works

European Central Bank key rates (deposit facility, main refinancing, marginal lending) with the date they took effect, the history of deposit-rate changes in basis points, and the latest €STR overnight rate. Official ECB data.

## Output

A JSON object containing: (1) tipos — the three current ECB key rates (facilidad_deposito, operaciones_principales, facilidad_marginal) each with tipo_pct and desde date; (2) estr — the latest €STR overnight rate with its date; (3) ultimos_cambios_deposito — an array of recent deposit rate changes with date, change in basis points (cambio_pb), and resulting rate (deposito_pct); (4) fuente — source attribution string.
