🆓 Free Crypto News API

Real-time crypto news from 300+ sources with one HTTP call. No API key, no signup, no rate-limit paperwork. Live at **cryptocurrency.cv**.

For AI agents: `curl https://cryptocurrency.cv/api/news` • llms.txtllms-full.txtOpenAPI • MCP: `https://cryptocurrency.cv/api/mcp` • AGENTS.mdSKILLS.md

> ⭐ If this saves you time, star the repo. It helps others find it.


⚡ Quick Start

Thirty seconds, no key required. cURL works as-is:

bash
# Latest headlines from every source
curl https://cryptocurrency.cv/api/news

# Only the last two hours
curl https://cryptocurrency.cv/api/breaking

# Full-text search
curl "https://cryptocurrency.cv/api/search?q=bitcoin%20etf"

# Filter by category, cap the result size
curl "https://cryptocurrency.cv/api/news?category=defi&limit=20"

# Ask a question, answered from today's news (AI)
curl "https://cryptocurrency.cv/api/ask?q=why%20is%20ETH%20up%20today"

Every endpoint returns JSON, is CORS-enabled, and works from a browser, a script, or an agent tool call. Response shape:

json
{
  "articles": [
    {
      "title": "Bitcoin Hits New ATH",
      "link": "https://coindesk.com/...",
      "description": "Bitcoin surpassed...",
      "pubDate": "2026-01-02T12:00:00Z",
      "source": "CoinDesk",
      "timeAgo": "2h ago"
    }
  ],
  "totalCount": 150,
  "fetchedAt": "2026-01-02T14:30:00Z"
}

From code, `npm install @nirholas/crypto-news`:

ts
import { CryptoNews } from '@nirholas/crypto-news';
const news = await new CryptoNews().getLatest(10);

Python, Go, PHP, Rust, Ruby, Swift, Kotlin, Java, C#, and R clients live in `sdk/` as copy-in source; runnable samples for bots, agents, and 12 languages live in `examples/`.

AI endpoint examples

The AI routes need no key either. They run on the hosted Groq integration:

bash
# Natural-language question over today's news
curl "https://cryptocurrency.cv/api/ask?q=what%20happened%20with%20the%20SEC%20this%20week"

# One-paragraph summary of the current feed
curl "https://cryptocurrency.cv/api/ai/summarize"

# Emerging narratives, ranked by momentum
curl "https://cryptocurrency.cv/api/ai/narratives?emerging=true"

# Daily brief for a given date
curl "https://cryptocurrency.cv/api/ai/brief?date=2026-08-26&format=summary"

# Retrieval-augmented answer over the 662k-article archive
curl "https://cryptocurrency.cv/api/rag?q=bitcoin%20etf%20approval%20timeline"

Historical archive

662,047 articles (CryptoPanic English coverage from September 2017 plus Odaily Chinese coverage), enriched with tickers, named entities, sentiment and the BTC/ETH price and Fear & Greed reading at capture time.

bash
curl "https://cryptocurrency.cv/api/archive?date=2024-01"                 # one month
curl "https://cryptocurrency.cv/api/archive?ticker=BTC&limit=100"          # by ticker
curl "https://cryptocurrency.cv/api/archive?q=bitcoin%20etf"               # full text
curl "https://cryptocurrency.cv/api/archive?start_date=2025-01-01&end_date=2025-01-07"
curl "https://cryptocurrency.cv/api/archive?stats=true"                    # counts and coverage

🔮 MCP Server

Use the whole API from Claude Desktop, Claude Code, Cursor, or any Model Context Protocol client. 40+ tools (news, search, archive, sentiment, market data, portfolio); the full tool list is in mcp/README.md.

Hosted endpoint, zero install. A Streamable-HTTP server runs at `https://cryptocurrency.cv/api/mcp`:

json
{
  "mcpServers": {
    "crypto-news": {
      "url": "https://cryptocurrency.cv/api/mcp"
    }
  }
}

Claude Code, one line:

bash
claude mcp add --transport http crypto-news https://cryptocurrency.cv/api/mcp

Local stdio server. The same tools on your machine, published as `@nirholas/free-crypto-news-mcp` (source in `mcp/`):

json
{
  "mcpServers": {
    "crypto-news": {
      "command": "npx",
      "args": ["-y", "@nirholas/free-crypto-news-mcp"]
    }
  }
}

Or run it from a checkout: `git clone https://github.com/nirholas/cryptocurrency.cv.git && cd cryptocurrency.cv/mcp && npm install && node index.js`.

Other agent surfaces: a ChatGPT custom GPT and OpenAI plugin manifest (`/.well-known/ai-plugin.json`), Google A2A agent card (`/.well-known/agent.json`), LangChain and CrewAI samples in `examples/agents/`, and copy-paste integrations for Discord, Telegram, Slack and LangChain in docs/reference/integrations.md.


🧩 Widgets

Embed a live news feed in any page with one script tag. Source and examples in `widget/`.

html
// Code block

`ticker.js` scrolls headlines, `carousel.js` renders cards, `embed.js` drops a full feed into a container. All three read `data-*` attributes for limit, category, speed and theme.


🐳 Self-Hosting

Everything runs from one Next.js app. All environment variables are optional; without any, you get the full news API. Set `GROQ_API_KEY` (free at console.groq.com) to switch on the AI endpoints. The complete variable list, Kubernetes manifests and observability stack are in docs/reference/self-hosting.md.

Docker

bash
git clone https://github.com/nirholas/cryptocurrency.cv.git
cd cryptocurrency.cv
docker compose up -d
# API on http://localhost:3000/api/news

The `Dockerfile` builds a standalone image; `docker-compose.yml` adds Redis for caching. Scale-out and observability variants: `docker-compose.scale.yml`, `docker-compose.observability.yml`.

Google Cloud Run

bash
gcloud builds submit --config cloudbuild.yaml

Step-by-step, including Artifact Registry, secrets and a custom domain: docs/DEPLOY-GCP.md.

Vercel

Deploy with Vercel

From source

bash
pnpm install
pnpm dev        # http://localhost:3000
pnpm build && pnpm start

Railway, Render, DigitalOcean, CasaOS, Unraid and Portainer templates are in the repo root (`railway.json`, `render.yaml`, `.do/`, `casaos-app.yaml`, `unraid-template.xml`, `portainer-template.json`). General deployment notes: docs/DEPLOYMENT.md.


🏗️ Architecture

1. Next.js 15 App Router on the Edge and Node runtimes; `src/app/api/` holds every route handler.

2. Source registry in `src/lib/crypto-news.ts` (RSS feeds by category) and `src/lib/international-sources.ts`; credibility tiers in `src/lib/source-tiers.ts`.

3. Fetch layer pulls feeds in parallel with per-source timeouts, dedupes by content hash, and normalises to the article schema above.

4. Caching at three levels: in-memory, Redis (optional), and CDN `s-maxage` headers, so a cold fetch is rare.

5. AI layer calls Groq for summaries, sentiment, fact-checks and briefs; RAG indexes the archive into pgvector (docs/RAG.md).

6. Archive is append-only JSONL by month, enriched with tickers, entities, sentiment and market context, exposed through `/api/archive`.

7. Realtime via SSE and a WebSocket server (`ws-server.js`) fed by the same fetch layer.

8. Payments: premium routes are gated by x402; the facilitator lives in `x402-facilitator/`.

9. Agents: MCP (hosted at `/api/mcp`, local in `mcp/`), OpenAPI, `llms.txt`, and `/.well-known/*` manifests are generated from the same route metadata.

10. Web app: 89 pages of React server and client components, installable as a PWA, localised into 42 languages.
