## What this connects

AddressZen provides address autocomplete and verification services, offering real-time address suggestions and validation to ensure accurate and deliverable addresses.

Vendor: https://addresszen.com/

## Tools available

**2** tools available. First 2:

- `ADDRESSZEN_KEY_AVAILABILITY` — Key Availability — Tool to get public information on an API key, including whether it is currently usable. Use when you need to verify that a key is valid and available before making further API requests.
- `ADDRESSZEN_RESOLVE_ADDRESS_USA` — Resolve Address USA — Tool to resolve an address autocompletion by its address ID and return the full address in US format. Use after obtaining an address suggestion ID from the autocomplete endpoint.

## Auth

Auth schemes: `API_KEY`.

## How agents use Addresszen

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

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

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