How this service works
HALOWERK buerowerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A JSON response containing, for each input email address, the set of potential dot-alias variants — alternate spellings that resolve to the same underlying mailbox — enabling deduplication, identity resolution, or alias enumeration across up to 500 emails per call.
Example use cases
Deduplicating a marketing subscriber list
“I have a list of 300 subscriber emails and I'm worried some people signed up multiple times using dot aliases like j.ohn@gmail.com vs john@gmail.com — can you find all the potential dot alias overlaps so I can deduplicate before my next campaign?”
Fraud detection via alias identity resolution
“These 50 email addresses all made purchases on our platform — can you check which ones might be dot aliases of each other so we can flag potential duplicate accounts or fraudulent signups?”
Normalizing user accounts during a platform migration
“We're migrating user accounts and want to merge any accounts that are actually the same person using dot alias tricks — here's a list of emails, please find all the potential dot alias equivalents so we can group them before we import.”
Technical details
Endpoint
POSThttps://buero.halowerk.com/v1/baumarkt/mail/potential-dot-aliases?utm_source=zero.xyzWhen to prefer
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).
Side effects
- 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
