Fun with RSS

The OP API outputs RSS for almost any query. Here are some combinations worth bookmarking.

v0.5

This page has been octothorped with these terms



BACKLINKS

Every OP query endpoint has an RSS variant — just add /rss before the query string. Everything you can filter in JSON, you can filter in a feed. These are live links; click any to open the feed.

The base pattern:

https://octothorp.es/get/[what]/[by]/rss?[params]

Follow a hashtag

The simplest feed: all pages tagged with a term.

get/pages/thorped/rss?o=cats

Fuzzy matching catches variant spellings — #indieweb, IndieWeb, indie-web:

get/pages/thorped/rss?o=indieweb&match=fuzzy


Combine tags

Comma-separate terms to get pages tagged with any of them:

get/pages/thorped/rss?o=indieweb,cats


Exclude a domain

Useful for following a tag without getting your own posts in the feed:

get/pages/thorped/rss?o=demo&nots=demo.ideastore.dev

Multiple domains, comma-separated:

get/pages/thorped/rss?o=smallweb&nots=demo.ideastore.dev,docs.octothorp.es


Exclude a tag

Get pages tagged with one thing but not another:

get/pages/thorped/rss?o=demo&noto=testing


Any page that octothorpes its outgoing links becomes a subscribable blogroll. This feed updates whenever the source page is re-indexed with new links:

get/pages/linked/rss?s=https://docs.octothorp.es/old-ways/blogrolls

Use feedtitle to give the feed a readable name in your reader:

get/pages/linked/rss?feedtitle=OP-blogroll&s=https://docs.octothorp.es/old-ways/blogrolls


Webring member posts

All indexed pages from sites in a webring:

get/pages/in-webring/rss?s=https://demo.ideastore.dev/demo-webring

Narrow it to webring members who also tagged a specific term:

get/pages/in-webring/rss?s=https://demo.ideastore.dev/demo-webring&o=demo


Date filtering

Recent posts only (last two weeks):

get/pages/thorped/rss?o=smallweb&when=recent

After a specific date:

get/pages/thorped/rss?o=smallweb&when=after-2024-01-01

Between two dates:

get/pages/thorped/rss?o=smallweb&when=between-2024-01-01-and-2024-12-31


Putting it together

A practical feed for following the indieweb and smallweb scenes, excluding a few high-volume domains, limited to recent posts:

get/pages/thorped/rss?o=indieweb,smallweb&nots=demo.ideastore.dev&when=recent&feedtitle=Indie%20%26%20Small%20Web

For the JSON equivalent of any of these feeds, just drop the /rss from the path.
