Lob.com US Autocompletions API

Given partial address information, this endpoint returns up to 10 address suggestions. back to top ## Autocompletion Test Env Your test API key does not autocomplete US addresses and is used to simulate behavior. With your test API key, requests with specific values for `address_prefix` return predetermined values. When `address_prefix` is set to: - `0 suggestions` - Returns no suggestions - `[PRIMARY NUMBER] s[uggestion]` - Returns a maximum of ten predefined suggested addresses. `[PRIMARY NUMBER]` does not have to be a valid primary number when sending a test request. Each additional letter in `suggestion` reduces the number of suggestions by one (e.g. `1 su` returns 9 suggested addresses). `[PRIMARY NUMBER]` does not affect the number of suggestions returned. City and state filters work as expected and filter the list of predetermined suggested addresses. See the `test` request & response examples under [Autocomplete Examples](#operation/autocompletion) within the "Autocomplete a partial address" section in US Autocompletions. back to top
