Street Address Parser API

About the Street Address Parser API

Street Address Parser works by analyzing the US street address provided and parsing the components. It uses advanced algorithms to parse the street address and returns the parsed components such as street number, street name, city, state, and more.

What people use it for

Mailing Label Printing

To prepare bulk shipping labels, fulfillment software isolates street numbers, street types, and ZIP codes from freeform buyer text.

Real Estate Ingestion

When property portals ingest raw MLS remarks, backend pipelines extract city and state abbreviations to index homes into regional search databases.

Voter Registration Intake

Separate unformatted residential entries into discrete building numbers and street names to match voter registrations against county records.

Tax Jurisdiction Lookup

Accounting platforms assign municipal sales tax rates by breaking customer billing strings into standardized city names and state codes.

Request parameters — GET /v1/streetaddressparser

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

curl "https://api.apiverve.com/v1/streetaddressparser?address=1600%20Amphitheatre%20Parkway%2C%20Mountain%20View%2C%20CA%2090210" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Response — GET /v1/streetaddressparser

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Zero-code embed — one snippet, no backend

Drop an interactive Street Address Parser form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.

Changelog — Street Address Parser API

Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
