What country code format should I use?
Use ISO 3166-1 alpha-2 country codes (e.g., US, CA, MX, GB). The API also accepts full country names.
Does it include maritime borders?
This API focuses on land borders only. Maritime boundaries and exclusive economic zones are not included.
How are island nations handled?
Island nations with no land borders return an empty borders array. This is accurate - they share no land boundaries with other countries.
How current is the border data?
Border data reflects current internationally recognized boundaries. We update the data when geopolitical changes occur.
Can I query by country name instead of code?
Yes, you can use either the ISO 2-letter code or the full country name as the parameter.
Does this include disputed territories?
The API uses internationally recognized borders. Disputed territories may vary based on recognition status.
