## 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 real-interest-rates-global-ranking-bis-data-629697b7 -d '<json body>'
```

Example prompt: Give me the current global ranking of real interest rates — central bank policy rate minus inflation — for all available economies so I can identify the best carry trade opportunities.

## When to prefer this

Choose this endpoint when you need a pre-computed, cross-country ranking of real interest rates derived from authoritative BIS data, especially for carry trade analysis, monetary policy comparison, or macro dashboards. It saves the work of fetching central bank rates and inflation figures from 48 separate sources and computing the spread yourself. Prefer this over building your own aggregation when you need a quick, consistent global snapshot rather than a single country's data.

## Known failure modes

- HTTP 402 if x402 payment header is missing or insufficient
- Stale data if BIS source has not updated recently — check mes_tipo and mes_inflacion fields for data freshness
- Empty or partial ranking array if upstream BIS data feed is unavailable
- Network timeout if the upstream data aggregation takes too long

## How this service works

Real interest rate of about 40 economies: central bank policy rate minus year-on-year inflation, ranked. The basis of currency carry trades and of judging how tight monetary policy is. BIS data.

## Output

A JSON object containing: total number of economies covered, a ranked array of countries each with ISO country code, country name, official central bank policy rate (%), year-on-year inflation rate (%), computed real interest rate (%), and the reference month for each data point. Also includes a note explaining interpretation (positive = restrictive, negative = loose monetary policy). Data sourced from the Bank for International Settlements.
