Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-postal-us-zipWhen to prefer
Choose this endpoint when you need a quick, cheap ZIP-to-location resolution for US postal codes without an API key, especially in agent workflows where you need to enrich address data with city, state, or coordinates. Prefer this over full geocoding APIs when you only have a ZIP code and need basic geospatial context rather than full address parsing.
Side effects
- Invalid or non-existent ZIP code returns an error or empty result
- Non-US postal codes are not supported
- Malformed input (e.g. 4-digit or alphanumeric codes) will fail validation
- Zippopotam.us database may lag on newly created ZIP codes
