REST API

Requests

Parameters to /parse (either GET or POST as application/x-www-form-urlencoded)

url
The URL of the feed that should be parsed (required). This parameter can be repeated multiple times. The values can be URL-encoded.
inline_logo
If set to 1, the (unscaled) logos are included in the response as data URIs (default 0).
scale_logo
If inline_logo is set to 1, scales the included logo down to the given size. The resulting image is fitted into a square with the given side-length. If the given size is greater than the original size, the image won’t be scaled at all.
logo_format
If inline_logo is set to 1, the inlined image is converted to the specified format (either png or jpeg). If this option is not used, the original format is preserved.
process_text
Is used to remove HTML from texts. Can be either none (does nothing, default if omitted), strip_html (removes HTML and inserts newlines, bullet points, etc) or markdown (converts HTML to Markdown).
use_cache
Feeds are cached by the service according to the feed’s caching headers. If use_cache is set to 1 (default) feeds are retrieved from the cache if possible. If set to 0, feeds are always fetched from their URL. Do not use 0 as a default value in your application.

Headers to /parse

If-Modified-Since
Time when all requested feeds have been accessed the last time. The response will only contain podcasts that have been modified in the meantime.
User-Agent
Clients should send a descriptive User-Agent string. In case of abuse of the service, misbehaving and/or generic user-agents might be blocked.
Accept
Clients should send Accept: application/json to indicate that they are prepared to receive JSON data. If you send a different Accept header, you will receive a HTML formatted response.
Accept-Encoding
Include gzip in both headers to ensure gzip compression.
