# PayAI Macro Compare — Cross-Country Indicator Comparison

> PayAI Macro Compare — Cross-Country Indicator Comparison is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Returns the latest value of a single macroeconomic indicator for multiple countries side-by-side, with computed signals: rank, highest, lowest, spread, mean, and source citations.

## 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 payai-macro-compare-cross-country-indicator-comparison-fdba086b
```

Example prompt: Compare inflation_cpi for the US, Germany, Japan, and Brazil — give me the latest value for each country, ranked highest to lowest, plus the spread and mean.

## When to prefer this

Use this endpoint when you need to compare a single macroeconomic or development indicator across multiple countries simultaneously and want computed signals (rank, spread, mean) rather than raw time-series data. Prefer this over the single-country time-series endpoint when the task is benchmarking or ranking countries rather than tracking trends over time for one country.

## Known failure modes

- Unknown indicator key returns an error or empty result
- Invalid or unrecognized country code/name causes missing data for that country
- No data available for the requested indicator/country/year combination
- Requesting fewer than two countries may not produce meaningful comparison signals
- Year parameter too far in the past may have no data for some indicators

## How this service works

One indicator compared across several countries: the latest value for each plus computed signals — rank, highest and lowest, spread and mean. Each value is cited to its source.

## Output

A JSON object containing: the latest available value of the requested indicator for each specified country, a ranking of countries by that value, the highest and lowest values with corresponding countries, the spread (max minus min), the mean across all countries, and a source citation for each data point.
