What it solves

Developers and AI agents need real-time crypto news without the hassle of API keys, signups, or rate limits. This project provides a free, open API that aggregates 300+ RSS feeds across 21 categories, plus 77 international outlets, and serves them through a single HTTP call. It also offers a historical archive of 662,047 articles from 2017 onward, AI-powered summaries and sentiment, and MCP support so LLM clients can query it directly.

How it works

The service runs as a Next.js app that fetches news feeds in parallel, deduplicates them, and normalizes the output to a consistent JSON schema. It exposes over 450 REST endpoints (news, search, market data, on-chain metrics, portfolio signals, etc.) and supports real-time streaming via SSE and WebSocket. The AI layer uses Groq to generate summaries, sentiment, and fact-checks, and a RAG system indexes the archive into pgvector for retrieval-augmented answers. Users can access it through cURL, language SDKs (12 languages), or an MCP server (hosted or local).

Who it's for

This is for developers building crypto dashboards, traders who want to monitor news, and AI/LLM developers who need news data for agents or chatbots. It's also for hobbyists who want a free data source without signing up for paid APIs. The project provides self-hosting options (Docker, Cloud Run, Vercel, etc.) for those who prefer to run it themselves.
