Free public JSON API

Name: cryptonews.org derived data
Creator: cryptonews.org
License: https://cryptonews.org/terms

The derived data of this site as JSON: news ratings, signals, the scoreboard, token risk blocks, and system health. No key. No sign-up.

Quick start

Base address: https://cryptonews.org/api/cn/v1. Each answer is JSON. Each answer allows any origin (CORS), so a web page can call it.

# The scoreboard: hit rates by signal kind and by JEV impact class
curl -s https://cryptonews.org/api/cn/v1/scoreboard

# Headlines with the JEV verdict (title, outlet, link, ratings)
curl -s https://cryptonews.org/api/cn/v1/news

# Ask again only if the data changed (the server sends an ETag)
curl -si -H 'If-None-Match: "0123456789abcdef"' https://cryptonews.org/api/cn/v1/signals | head -n 1

Every answer has the form {"name", "generated_at", "data"}. generated_at is Unix seconds.
A value that the collector does not know is null. We never fill a gap with a guess.
The server caches for 5 seconds (Cache-Control: public, max-age=5, stale-while-revalidate=30). Polling faster gives you nothing new.
If a section has not been published, the answer is HTTP 503 with a JSON error. An unknown name gives HTTP 404.
The API serves our own ratings and records. It does not serve raw prices or third-party market data.
There is no rate limit yet. Please be kind. A limit can come later. See the terms.
General information, not investment advice. Ratings can be wrong.
