# Content Types By default the MapaKalamidad API returns [JSON](http://www.w3schools.com/json/) for all calls and expects any POST requests to supply JSON formatted bodies unless otherwise advised. [UTF-8 encoding](https://en.wikipedia.org/wiki/UTF-8) is used on all requests and responses. Where Geographic data is returned this is will be encoded as [TopoJSON](https://github.com/topojson/topojson/wiki) by default. [GeoJson](http://geojson.org/) is also supported if required, by supplying `format=topojson in the API call. More details of this can be found in the specific API route documentation. In addition to TopoJSON and GeoJson we provide a public feed of real-time flood information using the`[`Common Alerting Protocol`](https://en.wikipedia.org/wiki/Common_Alerting_Protocol)`standard.` --- # 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.mapakalamidad.ph/master/general/encoding.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.
