## Content type distribution and API traffic share on Cloudflare Radar

[Radar](https://developers.cloudflare.com/radar/)

Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/changelog/post/2026-05-20-radar-content-type-and-api-traffic/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

[**Radar**](https://developers.cloudflare.com/radar/) now includes two new charts on the [traffic page ↗︎](https://radar.cloudflare.com/traffic) that provide deeper insights into the composition of HTTP traffic: a content type distribution chart and an API traffic share chart.

#### Content type distribution

The new [**Content type** ↗︎](https://radar.cloudflare.com/traffic#content-type) chart displays the distribution of HTTP response content types, grouped into high-level categories. A traffic type selector allows filtering by human, bot, or all traffic. The existing [**Bot vs. Human** ↗︎](https://radar.cloudflare.com/traffic#bot-vs-human) chart also gained a content type category filter, allowing users to see the bot/human split for specific content categories.

Content type categories:

- **HTML** — Web pages ( `text/html`)
- **Images** — All image formats ( `image/*`)
- **JSON** — JSON data and API responses ( `application/json`, `*+json`)
- **JavaScript** — Scripts ( `application/javascript`, `text/javascript`)
- **CSS** — Stylesheets ( `text/css`)
- **Plain Text** — Unformatted text ( `text/plain`)
- **Fonts** — Web fonts ( `font/*`, `application/font-*`)
- **XML** — XML documents and feeds ( `text/xml`, `application/xml`, `application/rss+xml`, `application/atom+xml`)
- **YAML** — Configuration files ( `text/yaml`, `application/yaml`)
- **Video** — Video content and streaming ( `video/*`, `application/ogg`, `*mpegurl`)
- **Audio** — Audio content ( `audio/*`)
- **Markdown** — Markdown documents ( `text/markdown`)
- **Documents** — PDFs, Office documents, ePub, CSV ( `application/pdf`, `application/msword`, `text/csv`)
- **Binary** — Executables, archives, WebAssembly ( `application/octet-stream`, `application/zip`, `application/wasm`)
- **Serialization** — Binary API formats ( `application/protobuf`, `application/grpc`, `application/msgpack`)
- **Other** — All other content types

The `CONTENT_TYPE` dimension and `contentType` filter are available on the HTTP [summary](https://developers.cloudflare.com/api/resources/radar/subresources/http/methods/summary_v2/), [timeseries groups](https://developers.cloudflare.com/api/resources/radar/subresources/http/methods/timeseries_groups_v2/), and [timeseries](https://developers.cloudflare.com/api/resources/radar/subresources/http/methods/timeseries/) endpoints.

#### API traffic share

The new [**API traffic** ↗︎](https://radar.cloudflare.com/traffic#api-traffic) chart shows the percentage of dynamic (non-cacheable) HTTP request traffic that is API-related. API traffic is identified by JSON or XML response content types (`application/json`, `application/xml`, `text/xml`) on HTTP requests that returned a 200 status code. A traffic type selector allows switching between human traffic, bot traffic, or all traffic.

The `API_TRAFFIC` dimension is available on the existing HTTP [summary](https://developers.cloudflare.com/api/resources/radar/subresources/http/methods/summary_v2/) and [timeseries groups](https://developers.cloudflare.com/api/resources/radar/subresources/http/methods/timeseries_groups_v2/) endpoints. An `apiTraffic` filter (`API` or `NON_API`) can also be applied to [HTTP timeseries](https://developers.cloudflare.com/api/resources/radar/subresources/http/methods/timeseries/) requests to retrieve raw request counts for API-only or non-API traffic.
