PostGrid Verify is an API that allows you to autocomplete, verify, and standardize addresses in real-time, supporting both individual and batch address verification.

Vendor: https://app.postgrid.com/

## Tools available

**12** tools available. First 12:

- `POSTGRID_VERIFY_AUTOCOMPLETE_ADDRESS` — Autocomplete Address — Tool to autocomplete a partially specified US or Canada address. Retrieves complete verified address including full postal code. Uses 1 lookup per request.
- `POSTGRID_VERIFY_AUTOCOMPLETE_INTL_ADDRESS` — Autocomplete International Address — Tool to retrieve complete verified international address data using an ID from the preview endpoint. Use when you have an address ID from the preview step and need the full address details.
- `POSTGRID_VERIFY_GET_AUTOCOMPLETE_PREVIEWS` — Get Autocomplete Previews — Tool to get previews of autocompleted US and Canadian addresses. Returns partial address data (line1, city, first 3 digits of postal code) without using any lookups. Use when you need quick autocomplete suggestions for address input.
- `POSTGRID_VERIFY_GET_INTL_AUTOCOMPLETE_PREVIEWS` — Get International Autocomplete Previews — Tool to get previews of autocompleted international addresses. Results are biased based on your current IP address unless disabled. Returns both 'Address' and 'BuildingNumber' types - if type is 'Address', its id can be used in POST /completions; if 'BuildingNumber', use the container id with advanced previews.
- `POSTGRID_VERIFY_GET_LOOKUP_INFO` — Get Lookup Info — Tool to retrieve lookup usage information for your PostGrid account. Use when you need to check how many lookups you have used and your free lookup limit.
- `POSTGRID_VERIFY_LOOKUP_CITY_STATE_FROM_POSTAL` — Lookup City and State from Postal Code — Tool to lookup city and state for a given postal or ZIP code. Use when you need valid city/state combinations for a postal code.
- `POSTGRID_VERIFY_PARSE_ADDRESS` — Parse Address — Tool to break an address apart into its components. Use when you need to extract individual address parts like street number, road, city, state, and postal code from a single-line address string.
- `POSTGRID_VERIFY_SUGGEST_ADDRESSES` — Suggest Addresses — Tool to find addresses similar to the given address. If the address can be verified or corrected, the first element will contain the verified address. Returns unit number ranges in line1 of suggested addresses. Use when you need address suggestions or corrections for US or Canadian addresses.
- `POSTGRID_VERIFY_VERIFY_ADDRESS` — Verify Address — Tool to verify and standardize a US or Canadian address. Supports both freeform addresses (single-line) and structured addresses (with separate line1, city, etc.). Use includeDetails=true for additional metadata or geocode=true for latitude/longitude.
- `POSTGRID_VERIFY_VERIFY_BATCH_ADDRESSES` — Batch Verify Addresses with Mixed Format — Tool to verify up to 2000 US and Canada addresses in a single API call. Accepts both freeform address strings and structured address objects. Each address uses 1 lookup credit.
- `POSTGRID_VERIFY_VERIFY_INTERNATIONAL_ADDRESS` — Verify International Address — Tool to verify and standardize international addresses from 245+ countries. Supports both structured and freeform address inputs. Use includeDetails=true for match levels and geoData=true for coordinates.
- `POSTGRID_VERIFY_VERIFY_INTL_ADDRESSES_BATCH` — Batch Verify International Addresses — Tool to verify up to 2000 international addresses in a single API call. Accepts both freeform address strings and structured address objects. Uses 1 lookup per address.

## How agents use PostGrid Verify

Inside a Definable workflow, PostGrid Verify is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → PostGrid Verify** — the Researcher (GPT-5.5) pulls context from PostGrid Verify (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → PostGrid Verify** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into PostGrid Verify (create record, post message, draft email).
- **Designer / Engineer → Distributor → PostGrid Verify** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via PostGrid Verify (attach file, open PR comment, post status).

The Verifier checks every PostGrid Verify call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
