FAQ

Does Cosmic Herald 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 640 of their articles and lets you filter by date, language and section.

How many articles does Cosmic Herald publish per day?

10 on a median day, measured across 28 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.
