How this service works
Returns population and weighted median household income for a geographic area around a US address or coordinates.

Example use cases
Example prompt

Technical details
Endpoint
GEThttps://x402datasource.com/api/v1/demographicsWhen to prefer
Use this endpoint when you need a quick, lightweight demographic snapshot (population + income only) for a geographic area around a specific US address or coordinates. It is faster and cheaper than the full detailed demographics endpoint. Ideal for real estate analysis, site selection, market sizing, or any scenario where only population count and median household income are needed.
Side effects
- Address cannot be geocoded — returns error if the address is invalid or outside the US
- Missing required input — returns error if neither address nor lat/lon is provided
- Invalid vintage year — returns error if a non-supported ACS year is specified (only 2022, 2023, 2024 available)
- No census tracts found in radius — may return null or zero values if radius is too small or in unpopulated area
- Payment failure — x402 payment of $0.01 USDC not completed, request rejected
