Transform any US address, coordinate, or ZIP code into more than 200 structured neighborhood signals — including demographics, economic strength, accessibility metrics, and percentile-ranked composite indices.
A limited free tier is available via RapidAPI .
TerraCore resolves any supported US location and returns more than 200 structured enrichment fields across 26 signal groups. Every field is normalized, typed, and engineered for real-world applications — from underwriting to site selection to portfolio analytics.
Population structure, age distribution, income bands, poverty levels, education attainment, labor force participation, housing stability, and insurance coverage — standardized into consistent, developer-friendly fields.
Walkability, grocery proximity, healthcare access, transit density, retail concentration, recreation access, and built-environment density — computed from normalized spatial feature extraction and radial modeling.
Percentile-ranked indices including Economic Strength, Household Stability, Growth Potential, Workforce Quality, Investor Yield, and Insurance Risk — benchmarked across the full national geography set.
Urban / Suburban / Rural classification derived algorithmically from density and infrastructure signals. Spatial metrics are percentile-ranked within peer zones for meaningful cross-market analysis.
fields parameter. Lean payloads. Deterministic scoring. Version-stable schema.
TerraCore powers applications that depend on reliable neighborhood intelligence — without managing data ingestion, spatial joins, or enrichment pipelines.
Enrich listings, valuation models, and investor dashboards with income distribution, housing stability metrics, density classification, school access, and walkability.
Inject deterministic neighborhood context into LLM prompts, enrichment workflows, underwriting engines, and analytics pipelines. Stable schema ensures predictable downstream integrations.
Programmatically enrich geographic datasets with workforce indicators, affordability metrics, economic strength scores, and structured comparisons across markets.
Evaluate candidate locations using transit access, retail density, demographic fit, workforce quality, and composite economic strength scores. Designed for franchise operators and expansion teams.
Append income bands, age structure, education levels, and affluence indicators to address datasets for geo-targeting, segmentation, and campaign optimization.
Model service areas and coverage zones using population density, zone classification, transit proximity, and community access metrics.
TerraCore does not compute enrichment on the fly. All demographic, environmental, and composite signals are precomputed at the census block-group level and served through a deterministic API layer for predictable latency.
Coordinate pair, ZIP code, 12-digit GEOID, or free-form address. All four methods on every endpoint.
High-performance PostGIS spatial containment, ZIP-weighted block-group aggregation, or address geocoding resolves input to a canonical census block group.
Field-group selective retrieval ensures lean payloads. Composite indices and spatial scores are served from precomputed tables — not assembled from raw Census variables at request time.
Flat, typed JSON response. No nested variable codes or downstream joins required.
TerraCore includes a dedicated indices field group of percentile-ranked scores (0–100) computed across ~242,000 US census block groups. Scores are deterministic and version-stable per data release. Higher is always better.
Unlike raw demographic APIs, TerraCore includes a library of derived neighborhood indices that summarize complex demographic and economic conditions into interpretable scores.
"Affluence" / purchasing power signal. Built from income strength, higher-income concentration, education attainment, labor conditions, and poverty inverse.
economic_strength_index
Neighborhood stability + lower-risk housing profile. Built from owner occupancy, vacancy pressure, income stress indicators, and housing value context.
household_stability_index
Rental fundamentals signal. Uses gross rent yield, renter concentration, vacancy inverse, and neighborhood income context to highlight yield-friendly areas.
investor_yield_index
Forward-looking "momentum" proxy. Built from prime-age concentration, education attainment, and work-pattern indicators that correlate with growth and demand.
growth_potential_index
Skilled labor availability proxy. Built from education levels, labor force participation, unemployment inverse, and commute accessibility indicators.
workforce_quality_index
Risk profile proxy using coverage and economic stress signals. Built from insurance coverage, poverty inverse, lower-income inverse, and ownership stability indicators.
insurance_risk_index
Housing affordability signal. Built from rent-to-income ratios, housing cost burden, and local income context.
affordability_index
Education attainment signal. Built from bachelor's and higher degree share, school access, and workforce education levels.
education_index
Family-centric neighborhood signal. Built from under-18 share, family household composition, owner occupancy, and single-family housing presence.
family_orientation_index
diversity_index, gross_rent_yield, vacancy_rate,
pct_owner_occupied, pct_renter_occupied, and full income bracket splits.
