Overview

Graph Countries API provides rich country data including currencies, languages, flags, bordering countries, and regional groupings via GraphQL. It is completely free with no authentication required, making it ideal for learning or building geography-based features. Send a GraphQL query to retrieve exactly the fields you need.

💡

Beginner Tip

This API uses GraphQL instead of REST, so you send a POST request with a JSON body containing your query. Use the GraphQL playground at the GitHub project to explore available fields before writing code.

Common Errors & Troubleshooting

✓ Validate your query in the GraphQL playground. Ensure you use double quotes inside the query and escape them correctly in shell.
null field value Requested a field that is not available for a particular country.
✓ Check the schema in the playground to see which fields are available. Handle null values gracefully in your code.
Network Error / CORS Browser-side requests may be blocked depending on the endpoint used.
✓ Use server-side requests or look for an alternative REST mirror of this dataset if CORS is an issue.
