# EconSignalPulse GDP Tracker

> EconSignalPulse GDP Tracker is a paid API for AI agents from econsignalpulse.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Compares real GDP growth data from World Bank against IMF forward projections for 190+ countries, with revision analysis, peer benchmarking, and growth decomposition

## Facts

- Endpoint: GET https://econsignalpulse.vercel.app/api/econsignal/gdp-tracker
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/econsignalpulse-gdp-tracker-289b7944
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_g8VdBBHrrmx6znDHxIEZ5

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 econsignalpulse-gdp-tracker-289b7944
```

Example prompt: Pull the GDP tracker for Brazil — show me the World Bank real growth figures versus IMF forward projections for the last 5 years, including any revision history and how Brazil compares to its EM peers.

## When to prefer this

Use this endpoint when you need to cross-reference official GDP actuals (World Bank) with forward-looking IMF projections in one call, particularly for revision analysis or EM/frontier peer benchmarking. Prefer this over generic data APIs when you need structured decomposition of growth drivers and forecast accuracy metrics rather than raw time-series data alone.

## Known failure modes

- Country not found or unsupported — endpoint covers 190+ countries but fringe territories may return empty data
- IMF projection data lag — projections may not reflect the most recent WEO update
- Date range out of bounds — historical data may be limited for very early years or very recent quarters
- API returns 402 if x402 payment header is missing or USDC payment fails
- Rate limiting or timeout if too many countries requested simultaneously

## How this service works

Real GDP growth (World Bank) versus IMF forward projections for 190+ countries — revision analysis, peer comparison and growth decomposition. For macro and EM research agents.

## Output

Returns real GDP growth figures from the World Bank alongside IMF forward projections for the requested country or countries, including revision analysis showing how forecasts changed over time, peer group comparisons against similar economies, and a growth decomposition breaking down the drivers of GDP performance.
