## 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 u-s-census-geocoder-parsed-address-census-geographies-for-technology-1ab5ec78 -d '<json body>'
```

Example prompt: Can you geocode 4600 Silver Hill Rd, Washington, DC 20233 using the Census geocoder and give me the parsed address components and all the Census geography codes like tract, block, and county FIPS?

## When to prefer this

Choose this endpoint when you need both standardized address parsing AND Census geographic identifiers (tract, block, FIPS codes) in a single call, particularly for U.S.-based address enrichment workflows, demographic analysis pipelines, or compliance tasks requiring Census geography linkage. Prefer this over general geocoders when Census-specific identifiers are required rather than just latitude/longitude.

## Known failure modes

- Address not found or unrecognizable — returns empty or null geography fields
- Address outside supported coverage (non-US countries) — no result returned
- Ambiguous address matching multiple records — may return multiple candidates or lowest-confidence match
- Missing required fields (e.g. no street) — request may fail validation
- Rural or very new addresses may not yet be indexed in Census geocoder
