## 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 latamref-compare-cross-country-reference-data-series-6974e026
```

Example prompt: Compare VAT rates across Brazil, Mexico, Argentina, Colombia, Chile, and Peru — I need each country's current rate with the official source and effective date.

## When to prefer this

Use this endpoint when you need to compare a single official government reference metric (VAT, policy rate, minimum wage, CPI, corporate tax, etc.) across multiple Latin American countries in one call with authoritative source citations. Prefer this over general web search or news APIs when you need structured, dated, officially-cited data for compliance, financial analysis, or policy benchmarking across LatAm — especially when you need up to 10 countries simultaneously with consistent formatting.

## Known failure modes

- Invalid series ID — returns error if the series slug is not in the /catalog
- Invalid or unsupported country code — returns error for codes not covered by the 22-country dataset
- More than 10 countries requested — request rejected
- Missing required parameters (series or countries) — validation error
- Data temporarily unavailable for a specific country/series combination
- Network timeout or upstream government source unavailability

## How this service works

Compare one government reference series (VAT, policy rate, minimum wage, CPI, corporate tax...) across up to 10 Latin American countries in one call, each row cited to its official source with effective and last-confirmed dates

## Output

A structured JSON array with one row per requested country, each containing the current value of the requested series, the effective date, the last-confirmed date, and a citation to the official government or central bank source. Up to 10 countries returned in a single response.
