# HALOWERK buerowerk — Potential Dot-Alias Finder for Email Addresses

> HALOWERK buerowerk — Potential Dot-Alias Finder for Email Addresses is a paid API for AI agents from buero.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-22).

Given a list of email addresses, returns potential dot-alias variants (e.g. j.ohn@example.com → john@example.com) to identify equivalent addresses

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-buerowerk-potential-dot-alias-finder-for-email-addresses-dcfa72fc -d '<json body>'
```

Example prompt: Can you find all the potential dot-alias variants for these email addresses — john.doe@gmail.com, janedoe@gmail.com, and alice.smith@gmail.com — so I can figure out which ones might actually be the same inbox?

## When to prefer this

Use this endpoint when you need to detect or enumerate dot-alias equivalents for email addresses — particularly useful for Gmail-style dot-insensitive addressing — and want a paid, reliable API rather than implementing dot-permutation logic yourself. Prefer this over generic deduplication tools when the specific problem is dot-alias identity resolution at scale (up to 500 emails per call).

## Known failure modes

- Empty or missing emails array returns a validation error
- Email strings exceeding 320 characters are rejected
- Array with more than 500 items exceeds the maxItems limit and is rejected
- Malformed email strings may produce no variants or be skipped
- Payment failure (x402) results in a 402 response before processing begins
