## 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 official-central-bank-interest-rates-ecb-fed-d643bd9a
```

Example prompt: What are today's official ECB and Fed interest rates — I need the ECB deposit facility, main refinancing, and marginal lending rates plus the Fed funds target range and SOFR for a loan pricing model?

## When to prefer this

Choose this endpoint when an agent needs authoritative, official central bank policy rates for the Euro Area or United States — not market-implied rates or estimates. Ideal for loan pricing, DCF valuations, macro analysis, or compliance contexts where the data source must be named and official. Prefer over generic finance APIs when auditability and official sourcing are required.

## Known failure modes

- HTTP 400 returned for invalid or unrecognized region values (before any payment is charged)
- Service outage — not charged in that case
- If the official source (ECB or NY Fed) has not yet published today's rates, stale or missing data may be returned
- No historical rate data — only current/latest rates are available

## How this service works

Use when an agent needs today's central bank rates for loans, savings, valuation or macro answers: ECB key rates (deposit facility, main refinancing, marginal lending, with the date they took effect) and US Fed funds target range, effective fed funds rate (EFFR) and SOFR from the New York Fed. Official sources only, named in every answer. region=EA, US or all (default). Bad input: HTTP 400 before payment; outage is not charged.

## Output

A structured JSON object with official central bank rates per requested region: for the Euro Area, the ECB deposit facility rate, main refinancing rate, and marginal lending rate (each with effective date); for the US, the Fed funds target range, effective fed funds rate (EFFR), and SOFR — all sourced and labeled from the ECB and New York Fed.
