Postal Data API

Postal Data API validates and looks up postal codes, locations, coordinates, and regional metadata across more than 240 countries and territories.

What agents can do

Actions6

  • 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.

  • Get postal code metadata

    Return all available country-specific metadata for a postal code, such as coordinates, timezone, county, elevation, and administrative levels.

  • Lookup postal code

    Look up the city, region, and coordinates for a postal code.

  • Search postal codes by city

    Return all postal codes matching a city and optional region, including fuzzy-match details.

  • Validate postal code

    Check whether one postal code exists without treating a nonexistent code as an execution error.

  • Validate postal codes bulk

    Validate 1 to 1,000 postal codes synchronously, including mixed-country batches.

How it connects

You paste an API key from Postal Data API on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
