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 structured report including VIIRS-derived nighttime light intensity metrics, official GDP figures, a computed divergence score, and anomaly signals indicating whether reported economic activity appears consistent with satellite evidence — covering the requested country from a 100+ country dataset.
Example use cases
Validate emerging market growth claims
“Check the nighttime-lights data against the official GDP for Vietnam over the last year — I need to know if their reported economic expansion is actually showing up in the satellite imagery.”
Screen for statistical reporting fraud
“Run the VIIRS analysis on Russia and Belarus — I want to identify if their official GDP figures are consistent with what the satellite data shows about actual nighttime economic activity on the ground.”
Detect hidden economic contractions
“Compare the satellite nighttime-lights trends to the official numbers for several African nations — flag any countries where the lights are dimming but GDP is still reported as growing.”
Technical details
Endpoint
GEThttps://econsignalpulse.vercel.app/api/econsignal/nightlightsWhen to prefer
Use this endpoint when you need to cross-validate official GDP or economic activity figures against independent satellite evidence — particularly for countries with questionable statistical reporting, authoritarian governments, or opaque data agencies. Prefer this over pure GDP lookup endpoints when the goal is detecting data manipulation, economic deception, or unreported contractions.
Side effects
- Unsupported or unrecognized country code returns an error or empty result
- Satellite data lag may cause divergence readings to be behind latest GDP releases
- Payment not processed (x402 flow failure) returns 402 with payment instructions
- Temporary satellite data unavailability may return stale or cached readings
- Highly small or data-sparse countries may have low-confidence nightlight signals
