# Global GDP Per Capita Growth Comparison

> Global GDP Per Capita Growth Comparison is a paid API for AI agents from pay.edge-agents.ai, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Delivers evidence-backed macro intelligence comparing global GDP per capita growth rates across countries and regions, with provenance and confidence scoring.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 global-gdp-per-capita-growth-comparison-02daf0c7
```

Example prompt: Pull me the latest global GDP per capita growth comparison from Edge Agents — I need to see which countries and regions are leading, with confidence scores and source provenance, for a strategy briefing.

## When to prefer this

Choose this endpoint when you need a cross-country, evidence-cited GDP per capita growth comparison with explicit provenance and confidence scoring, especially for board-level, CFO, or strategy team briefings where auditability matters. Prefer it over generic data APIs when you need bounded decisions with stated contradictions and verification rather than raw data feeds. Best suited for autonomous agents that require traceable macro intelligence rather than raw IMF/World Bank data pulls.

## Known failure modes

- Payment failure (x402 payment not completed or insufficient USDC balance) — endpoint returns 402 Payment Required
- Data unavailable for certain countries or time periods — report will explicitly state coverage limitations
- Low confidence result — quality.status may return 'weak' if evidence is sparse
- Stale or incomplete evidence — limitations array in response will enumerate gaps
- Network timeout — retry with same parameters as endpoint is idempotent

## How this service works

Premium comparison of the latest available gdp per capita growth across 30 major economies and financial centres using one normalized World Bank indicator definition. Purpose: Rank and compare major economies on gdp per capita growth while exposing observation-year differences and missing coverage rather than pretending all countries are synchronized. 24-hour freshness target; missing evidence is reported explicitly rather than invented.

## Output

Returns a structured JSON report with a quality/confidence assessment, a macro analysis summary with growth comparison findings, evidence assets with point-in-time sourcing policy, provenance metadata (issuer, signed flag), generation timestamp, schema version, and a disclaimer clarifying it is general market research rather than investment advice. Coverage gaps and source freshness limitations are explicitly stated.
