Newsflash

Five years of corroborated news events, queryable by agents.
newsflash.sh watches 260+ outlets across geographies and
languages and collapses the noise into a deduped event graph — one happening,
every source that corroborated it, a confidence score — live to the minute and
backfilled five years deep, so agents can backtest on history and act on the
wire. Served over MCP, a CLI, a real-time SSE stream, and a plain
HTTP API.
Humans read; agents query. No account needed to start.
npx newsflash events -q "etf" -c crypto -n 5
npx newsflash stream -c crypto --min-sources 2
curl "https://newsflash.sh/api/events?q=fed&category=tradfi&limit=5"
MCP (primary — for agents)
The event graph is served over MCP's Streamable HTTP transport at
https://newsflash.sh/mcp — listed in the official MCP registry as
sh.newsflash/newsflash. Point any MCP host at it:
{
"mcpServers": {
"newsflash": {
"type": "http",
"url": "https://newsflash.sh/mcp",
"headers": { "Authorization": "Bearer nf_your_key" }
}
}
}
Claude Code plugin install:
/plugin marketplace add zatmonkey/newsflash
/plugin install newsflash@newsflash
The endpoint is stateless (each request independent). Tools: get_events,
get_event, search_articles, list_sources, corpus_stats. Setup guides for
Claude, Cursor, ChatGPT and other hosts: newsflash.sh/docs.
OpenClaw
A ready-made skill ships in this repo (skills/newsflash/) —
personalized daily briefings + real-time breaking-news alerts:
clawhub install newsflash # or: openclaw skills install git:zatmonkey/newsflash
Then tell your agent "set up my news briefing". It interviews you for interests,
schedules a daily brief, and (if you enable alerts) watches the live stream and
pings you when a story crosses your corroboration threshold.
CLI
A standalone, zero-dependency npm package (./cli, published as
newsflash):
npm i -g newsflash
newsflash events -q "etf" -c crypto --from 2026-07-10 -n 5
newsflash events --json -q fed | jq '.[0].sources'
newsflash sources

HTTP API
Base URL https://newsflash.sh:
| Method | Route | Purpose |
|---|
| GET | /api/events?q=&source=&category=&from=&to=&limit= | Deduped events |
| GET | /api/events/:id | One event + corroborating articles |
| GET | /api/articles?… | Raw article search |
| GET | /api/sources | Tracked sources + counts |
| GET | /api/stats · /api/health | Corpus size & freshness |
| GET | /api/stream | Real-time SSE push — event.new / event.corroborated as clustering commits |
| POST | /mcp | MCP server (Streamable HTTP) — the agent-facing surface |

OpenAPI
The full REST surface is described in openapi.yaml — an
OpenAPI 3.1 spec with exact request/response schemas for every endpoint above
(including the SSE stream and the auth flow), derived from the live API. Import
it into Pipedream, RapidAPI, Postman, or a custom GPT Action to drive Newsflash
from your own tooling, or generate a typed client with any OpenAPI generator.
Tiers
| Tier | Auth | Limit | How |
|---|
| test | none | 50 req/day (per IP) · 24h lookback · 1 stream | just call the API or MCP endpoint |
| free | API key | 1,000 req/day · 30-day lookback · 2 streams | newsflash login — email + one-time code |
| premium | subscription | 50,000 req/day · full 5-year archive · 10 streams | newsflash upgrade — $29/mo |
Pass the key as Authorization: Bearer nf_… (or x-api-key) — same gate for REST
and /mcp. Every response carries X-RateLimit-Limit / X-RateLimit-Remaining /
X-Newsflash-Tier; limits reset at midnight UTC. Keys are shown once and stored
only as hashes.
How the event graph works
New articles are normalized and matched against recent events using trigram
similarity — across categories, so a crypto outlet and a tradfi outlet
reporting the same happening corroborate one event. Above the similarity
threshold → the article attaches to the event and bumps its corroboration;
otherwise it seeds a new event. confidence = min(1, distinct_sources / 3) — an
event corroborated by 3+ independent outlets maxes out.
That makes the graph a signal instrument: agents can distinguish a
single-outlet rumor (confidence 0.33) from a story the whole press corps is
running (confidence 1.0, sources listed), and query the full archive to
backtest on history.
About this repository
This repo holds the open-source (MIT) client surface of Newsflash: the
zero-dependency CLI (cli/), the Claude Code plugin manifests
(.claude-plugin/), and the MCP registry manifest
(server.json). The Newsflash backend is a hosted service
operated at newsflash.sh and is not part of this
repository.
CLI development: cd cli && npm install && npm run build && node dist/index.js stats.
No runtime dependencies — Node ≥ 20 built-ins only.
