How this service works
HALOWERK buerowerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A JSON response listing, for each input email address, the potential case aliases or alternative address forms that could be associated with it, useful for deduplication, identity resolution, or fraud detection.
Example use cases
Deduplicating a contact database
“I have a list of 200 customer emails from our CRM and I think some are duplicates with different casing or aliases — can you find all the potential alias variants for each so I can merge them?”
Fraud detection alias check
“These 10 email addresses came in as new registrations and I want to know if any of them might be aliases or case variants of each other — can you pull the potential aliases for all of them?”
Email normalization before bulk send
“Before we send this marketing campaign, can you check these email addresses for potential case-variant aliases so we don't accidentally email the same person multiple times?”
Technical details
Endpoint
POSThttps://buero.halowerk.com/v1/baumarkt/mail/potential-case-aliases?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate possible alias or case-variant forms of email addresses in bulk (up to 500 at a time), particularly for deduplication, identity resolution, or fraud prevention workflows. It is distinct from simple email validation — it actively generates or resolves alias candidates.
Side effects
- Empty or missing emails array returns a validation error
- More than 500 emails in the array exceeds the maxItems limit and is rejected
- Individual email strings exceeding 320 characters are rejected
- Malformed email strings may produce empty alias sets or errors
- Payment failure via x402 protocol returns HTTP 402
