How this service works
US address metadata for agents and apps. Census tracts, congressional districts, school districts, and more.
Output
Returns a JSON object with the standardized address, state, county, zip code, timezone, lat/lng coordinates, state and county FIPS codes, census tract, census block, census block group, urban/rural classification, school district name, congressional district code and name, and the data sources used.
Example use cases
Find congressional district for address
“I need to know what congressional district 742 Evergreen Terrace, Springfield, IL 62701 falls in — can you look that up along with any other civic metadata?”
Get census tract and FIPS codes
“Can you pull the census tract, FIPS codes, and urban/rural classification for 350 Fifth Avenue, New York, NY 10118? I need it for a demographic analysis.”
Look up school district for home address
“We're helping a family figure out which school district their new home at 4829 Lacey Oak Loop, San Antonio, TX 78253 belongs to — can you find that along with the timezone and county info?”
Technical details
Endpoint
POSThttps://www.dorothydata.com/api/v1/enrich/paid?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured US government geographic identifiers (census tract, FIPS codes, congressional district, school district) for a single US address. Prefer this over generic geocoding APIs when civic, demographic, or policy-related metadata is required alongside coordinates.
Side effects
- Invalid or unrecognizable address returns an error or empty data object
- Non-US addresses are not supported and will fail
- Ambiguous addresses (e.g. missing city or state) may return incorrect or no results
- Payment failure via x402 protocol results in a 402 response and no data
- Rate limiting or service outage returns 5xx errors
