Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-postal-us-city-zipsWhen to prefer
Use this endpoint when you need a comprehensive list of all ZIP codes within a specific US city along with their geographic coordinates. It is ideal for territory mapping, delivery zone configuration, and address validation workflows where you need city-level postal granularity. Prefer this over manual lookups or geocoding APIs when you need the full ZIP code inventory for a city rather than a single coordinate.
Side effects
- Invalid or unrecognized state code returns an error or empty result
- City name misspelling or non-existent city returns empty or null results
- Cities spanning multiple counties or with ambiguous names may return incomplete results
- Rate limiting or payment failure ($0.06 USDC x402) blocks the request
- Non-US locations are not supported by this endpoint
