lob_verify_address — Verify a single US address for deliverability and return USPS-standardized/corrected components (ZIP+4, DPV codes, county, lat/lon). Pass structured components (primary_line, city, state, zip_code) OR a single freeform `address` string — not both. Example: lob_verify_address({ primary_line: "185 Berry St", secondary_line: "Ste 6100", city: "San Francisco", state: "CA", zip_code: "94107", _apiKey: "your-key" }) or lob_verify_address({ address: "185 Berry St Ste 6100 San Francisco CA 94107", _apiKey: "your-key" })
lob_verify_bulk — Verify a list of US addresses in one request. Each address is an object with primary_line, city, state, zip_code (secondary_line/recipient optional). Returns per-address deliverability + corrected components. Example: lob_verify_bulk({ addresses: [{ primary_line: "210 King St", city: "San Francisco", state: "CA", zip_code: "94107" }], _apiKey: "your-key" })
lob_autocomplete — Autocomplete a partial US address. Given a primary-line prefix (and optional city/state/zip), returns up to 10 full address suggestions. Suggestions are candidates, not guaranteed deliverable — verify with lob_verify_address. Example: lob_autocomplete({ address_prefix: "185 B", city: "San Francisco", state: "CA", _apiKey: "your-key" })
