Short answer

How can I use AI to verify client info?

Your AI uses Abstract API tools to check if VAT numbers are real and if email addresses actually work. This prevents typos and fake signups from entering your system. You'll see the breakdown of how the agent processes these checks below.

Where every issue lands.

Data validation outcomes

The AI sorts incoming data into these categories based on the API results.

VALID

Clean data accepted

The AI confirms the VAT and email are legitimate. It flags these records as safe to import into your CRM.

INVALID

Bad data caught

The AI identifies broken email formats or fake VAT numbers. It marks these for immediate rejection.

RISKY

Needs human review

The AI finds suspicious patterns, like a valid email but a mismatched VAT. It flags these for you to check manually.

REJECT

Automatic block

The AI detects high-risk entries that fail both checks. It prevents these from ever reaching your main database.

The workflow

What your AI does when data arrives.

The AI acts as a gatekeeper, running specific checks on every new piece of client information.

  1. Check email status

    The agent pings the email address to see if it's active and reachable. This stops bounces before they happen.

  2. Verify tax IDs

    The AI checks the provided VAT number against official records to ensure the company is registered.

    validate_vat

  3. Cross-reference details

    The agent compares the company name against the VAT data to catch mismatches. It uses the results from both tools to find inconsistencies.

  4. Flag for review

    If the data is partially correct but looks suspicious, the AI moves the record to a manual review queue.
