## When to prefer this

Use this endpoint when you need to validate, parse, or normalize a single postal address string before storing it in a database, sending mail, or displaying it to users. Ideal for data cleaning pipelines, e-commerce checkout validation, or CRM address enrichment where address accuracy is important.

## Known failure modes

- Invalid or non-existent address returns validation failure or error flag
- Ambiguous address string may result in low confidence or multiple candidates
- Missing required address fields in input may return a parsing error
- Non-US addresses may not be supported or may return incomplete validation
- Malformed input string may return a 400 bad request error
