Cointelegraph API: Get Crypto News as JSON Without a Key

Cointelegraph doesn't publish a documented news API. Its website, though, loads articles from a GraphQL endpoint at https://conpletus.cointelegraph.com/v1/ that answers plain POST requests with no key. One query gives you the latest articles or keyword search results as JSON: title, publish time, lead text, category and view count. Full article bodies need a second query per article, by slug. For just the headlines, https://cointelegraph.com/rss is simpler.

This guide shows both routes with code that ran against the live endpoints on 2026-09-29. It also covers the quirks that trip people up: the empty bodyText, the CORS lock, and a language code that doesn't mean what it looks like.

Two free sources, and when to use each

Source	URL	Gives you	Limits
RSS feeds	https://cointelegraph.com/rss, /rss/tag/bitcoin, /rss/category/analysis	The latest items as XML	30 items per feed in testing; no search; no paging back in time
GraphQL	https://conpletus.cointelegraph.com/v1/ (POST)	Latest articles, keyword search, single articles with body HTML, view counts, 14 working language editions	Undocumented and internal, so it can change without notice

RSS is the stable, sanctioned option for "what's new right now". GraphQL is what you need for keyword search, history, view counts or full text.

The GraphQL shape

Everything hangs off locale(short: "<code>"). Inside it, three queries matter:

• posts(order: "postPublishedTime", offset, length) returns the latest articles, newest first
• postsSearch(offset, length, query) returns keyword search results
• post(slug) returns one article, including its body

Both list queries return { data: [Post], hasMorePosts }. The fields you'll use on a Post:

Field	Type	Notes
id	string	Article ID
slug / url	string	url is a relative path such as /news/...
views	int	View count
postTranslate.title	string	Headline
postTranslate.published	string	ISO-8601 with UTC offset
postTranslate.leadText	string	The summary paragraph
postTranslate.bodyText	string (HTML)	Filled in by post(slug) only (see below)
postTranslate.publishedHumanFormat	string	Came back null in every test
category.slug	string	For example markets or latest-news
postBadge.label	string or null	Badge label, often null
author.authorTranslates[].name	string	Byline

Python: search Cointelegraph and save CSV

This needs only requests:

import csv
import time
import requests

ENDPOINT = "https://conpletus.cointelegraph.com/v1/"

QUERY = """
query Search($short: String!, $offset: Int!, $length: Int!, $query: String!) {
  locale(short: $short) {
    postsSearch(offset: $offset, length: $length, query: $query) {
      hasMorePosts
      data {
        id
        url
        views
        postTranslate { title published leadText }
        category { slug }
        postBadge { label }
      }
    }
  }
}

Node.js: latest articles with full text

The list and search queries return bodyText as an empty string. I checked posts and postsSearch, for both recent and older articles. To get the body, ask for each article by slug:

// Node 18+ (built-in fetch). Latest articles + full body text.
const ENDPOINT = "https://conpletus.cointelegraph.com/v1/";

async function gql(query, variables) {
  const res = await fetch(ENDPOINT, {
    method: "POST",
    headers: { "content-type": "application/json", origin: "https://cointelegraph.com" },
    body: JSON.stringify({ query, variables }),
  });
  if (!res.ok) throw new Error(`HTTP ${res.status}`);
  const { data, errors } = await res.json();
  if (errors?.length) throw new Error(errors[0].message);
  return data;
}

const LATEST = `
  query Latest($short: String!, $offset: Int!, $length: Int!) {
    locale(short: $short) {
      posts(order: "postPublishedTime", offset: $offset, length: $length) {
        hasMorePosts
        data { id slug url views postTranslate { title published } }
      }
    }
  }`;

const ONE_POST = `
  query One($short: String!, $slug: String!) {
    locale(short: $short) {
      post(slug: $slug) { postTranslate { bodyText } }
    }
  }`;

const lang = "en";
const list = await gql(LATEST, { short: lang, offset: 0, length: 5 });

for (const p of list.locale.posts.data) {
  // List and search queries return an empty bodyText; fetch the post by slug for the body.
  const one = await gql(ONE_POST, { short: lang, slug: p.slug });
  const html = one.locale.post?.postTranslate?.bodyText ?? "";
  const text = html.replace(/<[^>]+>/g, " ").replace(/\s+/g, " ").trim();
  console.log(p.postTranslate.published.slice(0, 10), p.views, p.postTranslate.title);
  console.log("   ", text.slice(0, 120), `... (${text.length} chars)`);
  await new Promise((r) => setTimeout(r, 300));
}

Save it as latest.mjs and run node latest.mjs. Each article prints with a body of roughly 1,200 to 4,100 characters, where the list query alone gave 0.

Pitfalls, stated precisely

• It's an internal endpoint. Cointelegraph doesn't document conpletus or promise it'll stay stable. Check for errors in every response, and alert when a page comes back empty, not only when the request fails.
• Browsers are blocked by CORS. The endpoint answers with access-control-allow-origin: https://cointelegraph.com, so a fetch() from any other site fails in the browser. It works from a server, a script or a notebook. That's why the free tool below builds the query instead of running it in your browser.
• Empty bodyText in lists. As shown above, you need the extra post(slug) call for the full text. Budget one request per article.
• Paging. offset and length work as you'd expect. length values up to 200 were accepted, and an offset of 20,000 still returned articles (from September 2024). Stop when hasMorePosts is false or a page comes back empty. Deduplicate by id in case a new article shifts the offsets while you page.
• Language codes aren't all what they look like. ar resolves to cointelegraph.com.ar, which looks like an Argentinian domain but serves the Arabic edition (Arabic titles, lang="ar"). jp resolves to cointelegraph.jp. my returns no data. To check what a code maps to, query locale(short: "xx") { language { domain short } }, and build absolute URLs from that domain, not from cointelegraph.com.
• publishedHumanFormat is null. Format published yourself.
• Copyright. Articles are copyrighted. Use the data for research, monitoring and analysis, not for republishing full text, and read Cointelegraph's terms before you scrape at volume.

Do it without code

The free Cointelegraph query builder is a query builder, not a live fetcher. The CORS lock above rules out a live in-browser call. You set a keyword, a language edition and an article count, and it builds a ready-to-run input for the actor below. It also shows a fixed example of the output fields, so you can plan the schema before you run anything.

At scale

A one-off script is fine for a single search. For a scheduled crypto-news feed, you also need retries, deduplication across runs, language editions, and exports that feed a sentiment model or dashboard. The Cointelegraph News Scraper actor on Apify handles the retries, per-run deduplication, language editions and exports on top of the same GraphQL backend. Deduplicating across scheduled runs is still up to you: key on the article id. It takes a keyword or pulls the latest articles, collects 5 to 100,000 per run, includes view counts and full article text (for up to 10,000 articles per run), and exports JSON or CSV. It's free to start, then pay-as-you-go.

Disclosure: I build the datatooly builder and the Apify actor. The endpoints and code above work without either.

FAQ

Does Cointelegraph have an official API?

It has no documented public news API. The site runs on a GraphQL endpoint (conpletus.cointelegraph.com/v1/) that accepts POST requests without a key, and it publishes RSS feeds at cointelegraph.com/rss.

Do I need an API key?

No. Neither the GraphQL endpoint nor the RSS feeds needed a key or cookie in testing. The code sends an Origin: https://cointelegraph.com header to match what the site itself sends.

Why is bodyText empty?

The list and search queries return an empty bodyText. Request the article with post(slug: "...") inside locale(short: "en") to get the full HTML body.

Can I call it from browser JavaScript?

Not from your own site. CORS only allows the https://cointelegraph.com origin. Run it server-side, or use the RSS feed through your own backend.

How far back can I go?

Offsets deep into the archive work. An offset of 20,000 on the English edition returned articles from September 2024. Page with offset and length until hasMorePosts is false.

Which language codes work?

These 14 codes all returned articles on 2026-09-29: en, tr, de, es, fr, it, jp, kr, br, cn, ar, in, tw and ru. ar is the Arabic edition, served from cointelegraph.com.ar despite the Argentinian-looking domain, and my returned no data. Query language { domain } to confirm a mapping.
