Example prompt: Can you check whether my online business has sales tax nexus obligations? I've made $120,000 in sales and 250 transactions into Texas this year — do I need to register and collect sales tax there?

## When to prefer this

Use this endpoint when you need to programmatically determine sales tax nexus obligations for a business based on transaction volume, revenue, or physical presence — particularly for e-commerce sellers operating across multiple U.S. states. Prefer this over manual lookup when automating compliance checks at scale or when building tax compliance workflows.

## Known failure modes

- Incomplete or ambiguous input data string may result in incorrect nexus determination
- Missing state-specific revenue or transaction count figures may prevent accurate threshold comparison
- API may return generic response if business type or industry is not clearly specified
- Outdated nexus threshold data if the service's reference data is not current with recent state law changes
