Endpoint
GEThttps://rotaryagency.uk/api/free/zip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call ZIP code lookup without a subscription, especially in agentic workflows where you only need occasional ZIP-to-location resolution. At $0.002/call it is cost-effective for low-to-medium volume use. Prefer alternatives if you need bulk batch processing or international postal code support.
Side effects

- Non-US ZIP codes may not be supported
- Malformed ZIP code (wrong length or non-numeric) returns a validation error
- Rate limiting or payment failure results in a 402 or 429 response
