# Fallback

Glossary · Agents

Canonical page: https://datasdk.ai/glossary/fallback

A fallback is the behavior used when the preferred result is unavailable.

## Why it matters

Keep a workflow usable when lookups fail or fields are missing.

## Illustrative example

An interface shows no company match instead of inventing a business name.

## What to check

A sample record must stay labeled and must not masquerade as a live match.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
