## 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 fittings-address-standardizer-913d0ed3
```

Example prompt: Can you standardize this address into proper USPS format and pull out the individual components — I have '123 main st apt 4, new york ny 10001'?

## When to prefer this

Choose this endpoint when you need to normalize and parse a raw, user-entered US address string into structured USPS-compliant components — particularly useful for data cleaning, form validation, and pre-processing before geocoding. Prefer it over geocoding endpoints when lat/lng coordinates are not needed and the goal is purely address standardization and component extraction. It is faster and cheaper than full geocoding for address formatting tasks alone.

## Known failure modes

- Address cannot be parsed or recognized — returns an error or empty result
- Non-US address submitted — coverage is US-only, international addresses will fail
- Address string exceeds 200 characters — rejected by input validation
- Ambiguous or incomplete address (e.g. missing city/state/ZIP with no context) — may return low-confidence or no result
- Malformed or gibberish input — returns parse error

## How this service works

Normalize a free-text US street address into its USPS-style standardized one-line form plus parsed components: house number range, directionals, street name, suffix, city, state and 5-digit ZIP.

## Output

Returns the USPS-style standardized one-line address string alongside individually parsed components: house number or range, pre-directional and post-directional, street name, street type suffix, city name, two-letter state abbreviation, and 5-digit ZIP code.
