Kallax.io has a public REST API that is described by an OpenAPI specification. Use it to build your own tools on top of Kallax.io data, or to give an AI assistant a way to call Kallax.io.
The API is read-only and only returns what anyone could see on Kallax.io without signing in. You don’t need an account or an API key.
Where to find the specification
The OpenAPI specification is available as JSON:
Import the address into any tool that understands OpenAPI, such as Postman, Insomnia or a code generator.
This API is provided as-is. No guarantees are made about general availability. It may be updated, changed, or removed at any time without prior notice.
Using the API
The API base address is https://kallax.io. Every endpoint returns JSON. The specification is always up to date, so it is the place to look for the available endpoints, parameters and responses.
