Look at your data without changing it.
- Get API Information
Return Postal Data API version, coverage, usage guidance, current balance, and configured rate-limit status when returned, for connectivity or service discovery. The provider does not document this endpoint as unbilled, so assume it may consume one query.
- Get Postal Code Metadata
Return all available country-specific metadata for a postal code, such as coordinates, timezone, county, elevation, and administrative levels. The metadata fields vary by country and availability. Each successful call consumes one Postal Data API query.
- Look Up Postal Code
Look up the city, region, and coordinates for a postal code. Use this for a concise location result; use Get Postal Code Metadata for country-specific administrative details. Each successful call consumes one query.
- Search Postal Codes by City
Return all postal codes matching a city and optional region, including fuzzy-match details. For US searches, provide a state name or state code. Each successful call consumes one Postal Data API query.
- Validate Postal Code
Check whether one postal code exists without treating a nonexistent code as an execution error. Inspect valid in the response. Each successful call consumes one Postal Data API query.
- Validate Postal Codes in Bulk
Validate 1 to 1,000 postal codes synchronously, including mixed-country batches. Results preserve input order and report per-record failures. A batch of N records consumes N queries and is rejected atomically if balance or rate-limit budget is insufficient.
