Three ways to validate

No new workflows. No new tools.

Upload a CSV, call the API, or connect your CRM. Same validation engine, same results.

CSV Upload

Upload a file. Get clean data back.

Upload any spreadsheet with addresses, emails, or phones. DQVerify processes every row and returns an enriched file with validation status — no code required.

No IT project · No setup · Results in minutes
REST API

One call. Three validations.

A single POST returns validated address, email, and phone in one JSON response. Sub-150ms. SDKs for Node.js, Python, PHP, and Go.

curl -X POST https://api.dqverify.com/v1/validate \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"address":"350 5th Ave, New York NY",
