Four ways to pull nautil.us

All four are ours, all four are live, and none of them needs a key.

What this outlet covers, by share of its recent output:

Call the API

A live request. Paste it into a terminal and Nautilus headlines come back as JSON.

curl "https://freenewsapi.ai/v1/search?host=nautil.us&size=5"

Publishing volume

Articles per day over the last 73 days. The busiest hour is 12:00 UTC — that is when the newsroom pushes its main batch.

The 1 hatched days are gaps in the upstream news archive, not quiet days at Nautilus: the whole corpus dips on those dates. They are excluded from the median above.

Publishing rhythm

When Nautilus actually publishes, by hour of day (UTC) and by day of week — measured from 793 timestamps, not from a schedule they advertise.

Sections

Sections come from the publisher's own markup, present on 80% of their articles.

Languages

The site identifies itself under Nautilus, nautil.us — separate editions publishing under one domain.

Latest articles

The 18 most recent Nautilus articles in the index — the same rows the API returns, rendered for humans.

FAQ

Does Nautilus have an official API?

Not a public one. This endpoint is the practical alternative: their articles as structured JSON, with title, lead, publication time, section, byline and a link back to the original.

How do I get their RSS feed?

Most publishers expose one at /rss or /feed, but feeds carry only the last few dozen items and drop them within hours. This index keeps 793 of their articles and lets you filter by date, language and section.

How many articles does Nautilus publish per day?

6 on a median day, measured across 73 days.

Can I use this commercially?

The API is free and unauthenticated. What you may do with the content is between you and the publisher: we return metadata, a lead paragraph and a link, not a licence.
