# Earthscale HTTP API This is the API that can be used to add and list datasets. We recommend to use the [Python API](/python-api/getting-started.md) for this, since it makes it easier to authenticate. If you need help with using the HTTP API directly, please contact . Dataset responses from this API return the URLs of the tilers that can be used to retrieve raster tiles or pixel information. The available tilers depend on the dataset type and whether or not the dataset has been accelerated already: * The [dynamic tiler](/http-api/dynamic-tiler-http-api.md) works for any dataset. * Performance depends on the source data structure * The [fast tiler](/http-api/fast-tiler-http-api.md) is only available for accelerated (pre-processed) datasets * Always high-performance Both of these tilers use API keys to authenticate, so they are easy to integrate into your applications. The easiest way to obtain URLs for them is from the Earthscale web application (see [Use Earthscale in Your Products](/earthscale-documentation/use-earthscale-in-your-products.md)) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.earthscale.ai/http-api/earthscale-http-api.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
