# EconSignalPulse Nightlights GDP Divergence Analyzer

> EconSignalPulse Nightlights GDP Divergence Analyzer is a paid API for AI agents from econsignalpulse.theaslangroupllc.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-14).

Compares VIIRS satellite nighttime-lights data against official GDP figures to detect statistical divergence between reported economic activity and satellite-observable evidence across 100+ countries.

## Facts

- Endpoint: GET https://econsignalpulse.theaslangroupllc.com/api/econsignal/nightlights
- Price: $0.15/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/econsignalpulse-nightlights-gdp-divergence-analyzer-7c07bc51

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-nightlights-gdp-divergence-analyzer-7c07bc51
```

Example prompt: Can you check whether China's official GDP figures line up with what VIIRS satellite nighttime-lights data is showing — I want to know if there's a significant divergence between the two and what the gap looks like?

## When to prefer this

Use this endpoint when you need to cross-validate official GDP or economic activity figures for a specific country against independent satellite evidence, particularly for countries with questionable data reporting quality (authoritarian regimes, frontier markets, sanctioned states). Prefer this over general macro endpoints when the core question is data integrity or statistical divergence rather than forecasting.

## Known failure modes

- Country not in supported list (100+ supported — rare but possible for micro-states)
- Insufficient satellite data coverage for the requested period
- Official GDP data not yet available for the requested time window
- Invalid or unrecognized country identifier returns 400 error
- Rate limiting or payment failure returns 402 or 429 error

## How this service works

VIIRS satellite nighttime-lights analysis versus official GDP — detects divergence between reported activity and satellite evidence across 100+ countries. For hedge-fund and intelligence agents.

## Output

Returns a comparison of VIIRS satellite nighttime-lights intensity versus official GDP figures for a specified country, including a divergence metric or score indicating whether reported economic activity is statistically consistent with satellite-observable evidence, flagging potential over- or under-reporting.
