What can you build with IPinfo API?
IPinfo API is a Developer Tools API. Developers commonly use developer tools APIs for:
- automating code review and quality checks
- integrating CI/CD pipelines and build systems
- managing feature flags and A/B tests
- monitoring errors and application performance
- generating and validating test data
Bearer token. Your app exchanges credentials for a short-lived token, then sends it as an Authorization header. Tokens expire, so your code needs to handle renewal. IPinfo API is free to use up to a usage limit, making it a low-risk choice to experiment with.
