## 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 bis-real-effective-exchange-rate-reer-by-country-4e5f3d40 -d '<json body>'
```

Example prompt: Show me the current BIS real effective exchange rate ranking across all 64 economies, including the annual change for each country, so I can see which currencies have appreciated or lost competitiveness the most.

## When to prefer this

Choose this endpoint when you need inflation-adjusted (real) exchange rate data benchmarked against a broad 64-economy basket sourced directly from BIS — as opposed to nominal exchange rates from forex APIs. It is ideal for macroeconomic competitiveness analysis, trade policy research, or comparing how much a currency has strengthened or weakened in real purchasing-power terms over time.

## Known failure modes

- Invalid or unrecognized country code returns an error or empty result
- Requesting a country not in the 64-economy BIS basket returns no data
- BIS data may have a publication lag of 1-2 months, so the most recent month may be unavailable
- Omitting the 'type', 'method', and 'bodyType' required fields causes a validation error

## How this service works

Real effective exchange rate of a currency against 64 economies (inflation-adjusted): rises mean the currency gets dearer and the country loses competitiveness. Ranking with annual change, or one country's series. BIS data.

## Output

Returns a JSON object with the BIS data source label, the number of economies covered (up to 64), and either a ranked array of all countries (each with ISO code, country name, index value relative to 2020=100, reference month, and annual percentage change) or a time-series for a single country — enabling both snapshot ranking and longitudinal trend analysis.
