Binance News cites NS3 as a news source ("According to NS3.AI") across hundreds of articles daily. Recent examples: | |
Traditional news sources deliver only raw articles that still need to be classified, translated, and reformatted before use. NS3 delivers all of that already done by AI. Every article arrives pre-classified by importance (Level 1–5), enriched with 5-section AI Insight, and tagged by news type and related coins. No other crypto news data provider classifies every article by importance and delivers structured analysis.
Fact Sanctity: Facts and analysis are strictly separated. Fact-only fields (title, summary, Key Point) contain only what the article explicitly states. Analysis sections (Market Sentiment, Similar Past Cases, Ripple Effect, Opportunities & Risks) perform limited inference based strictly on the article's stated facts.
Earned Importance: Classification answers four questions in order: Would a crypto market participant need to know this today? (Level 1–2), Nice to know but can wait until tomorrow? (Level 3), Anything to analyze beyond the headline? (Level 4 if not), Journalism or promotional noise? (Level 5 if noise). Level 2 must be earned by matching a condition in the structured condition table across seven categories (regulation, institutional products, macro data, market structure, capital flows, geopolitical shock, crypto ecosystem shift). Level 1 is reserved for systemic events requiring immediate attention from all market participants — all three conditions must hold: systemic scope, already executed, and immediate transmission. When classification is uncertain, AI always downgrades by one level. Underestimation is better than overestimation. If NS3 says Level 1-2, it matters.
Mechanism-Based Analysis: Ripple Effect specifies transmission pathways: trigger, channel, market behavior. Level 1-2 includes diagnostic "If/Then" confirmation cues that help validate whether spillover is activating or contained. Level 3 provides a propagation assessment: either the single most direct transmission channel, or an explicit containment statement explaining why the impact stays local.
Advisory Restraint: Opportunities & Risks uses conditional triggers only: "If X happens, then Y is a signal to..." No price targets, no position sizing, no direct investment advice.
Promotional noise is blocked and never delivered: sponsored/advertorial content, presale/ICO/IDO promotion, casino/gambling promotions, exchange marketing campaigns (trading competitions, signup bonuses, fee discount events), airdrop claim guides, media self-promotion (subscription/event/app promotions), editorial-wrapped promotions with unverifiable claims about unknown projects, affiliate-driven ranking listicles, clickbait price predictions with no analytical basis, and recurring pick-list filler.
16 Language Support
All four feeds are delivered simultaneously in 16 languages. When the user communicates in a non-English language, use the corresponding language code instead of en. This saves tokens (no agent-side translation needed) and delivers professional-grade financial translation.
Language codes: en (English), zh-CN (简体中文), zh-TW (繁體中文), ko (한국어), ja (日本語), ru (Русский), tr (Türkçe), de (Deutsch), es (Español), fr (Français), vi (Tiếng Việt), th (ไทย), id (Bahasa Indonesia), hi (हिन्दी), it (Italiano), pt (Português)
Replace lang=en with the target language code in any feed URL. Example:
# English
curl -s "https://api.ns3.ai/feed/news-data?lang=en"# Korean
curl -s "https://api.ns3.ai/feed/news-data?lang=ko"# Japanese
curl -s "https://api.ns3.ai/feed/news-data?lang=ja"
When to Use Which Feed
NS3 has two independent pipelines delivering four feeds. Pipeline A reads every article published across 20+ media outlets, analyzes each one, and produces three feeds (News, Top News, Daily Briefing). Pipeline B takes breaking headlines from paid services (Bloomberg Terminal, Reuters), rewrites them, and delivers News Flash. The two pipelines are complementary: News Flash delivers breaking headlines first, then News RSS follows with in-depth analysis.
Token guidance: News RSS returns up to 100 items by default and can consume 60,000-100,000 tokens. Always use limit=20 and at least one filter (crypto, newsType, or excludeLevels) when calling News RSS.

How AI Classification Works
Every article passes through a four-stage classification pipeline:
Stage 1 (L5 Filter): Removes promotional noise: sponsored content, advertorials, editorial-wrapped promotions with unverifiable claims, affiliate listicles, and clickbait price predictions. Genuine reporting on any topic (including non-crypto) passes to Stage 2. Classified as Level 5 and excluded from the feed entirely.
Stage 2 (L4 Filter): Separates routine and analysis-thin content. Digests, routine notices, contextless data points (on-chain movements without stated cause, non-systemic liquidation snapshots, catalyst-free price alerts), opinions, forecasts, chart analysis, and unexecuted governance proposals are classified as Level 4.
Stage 3 (L2 Condition Table): Articles passing Stages 1-2 are checked against a structured condition table across seven categories: (1) Regulation/Legal, (2) Institutional/Product Launch, (3) Macro Data/Policy, (4) Market Structure/Security, (5) Institutional Capital Flows, (6) Geopolitical/Macro Shock, (7) Crypto Ecosystem Shift. If the article matches any condition, Level 2. If no condition matches, Level 3.
Stage 4 (L1 Override): Only Level 2 articles are eligible for upgrade to Level 1. All three conditions must be met: systemic scope (can reprice broad risk assets market-wide), already executed (not planned or expected), and immediate transmission (impact reaches participants within hours). When uncertain, AI always downgrades by one level.

Feed 1: News RSS
Real-time stream of every article with AI classification and analysis.
Token guidance: This feed returns up to 100 items by default. At 100 items, token consumption varies by level: Level 2 articles average ~940 tokens each, Level 3 ~680, Level 4 ~250. An unfiltered 100-item response consumes 60,000-100,000 tokens. Use the limit parameter to control result count and reduce token consumption.

Full archive retrieval only
Higher limit values do not return more recent news. They extend further back in time. limit=10 returns the 10 most recent matching articles. limit=50 returns the same 10 plus 40 older articles.
Always use limit and at least one filter (crypto, newsType, or excludeLevels). The unfiltered base URL with default limit=100 returns all levels including routine items and consumes excessive tokens.
# Best: specific coin + important only + limit (recommended)
curl -s "https://api.ns3.ai/feed/news-data?lang=en&crypto=SOL&excludeLevels=3,4&limit=20"# Good: specific coin + exclude routine + limit
curl -s "https://api.ns3.ai/feed/news-data?lang=en&crypto=BTC&excludeLevels=4&limit=20"# Acceptable: specific coin + all levels (use only when the user explicitly requests all news including routine items)
curl -s "https://api.ns3.ai/feed/news-data?lang=en&crypto=ETH"
Token filter (multi): Returns only news related to a specific token. The crypto parameter supports approximately the top 1,500 coins by CoinMarketCap ranking. Coins outside this range may return no results even if news about them exists in the feed.
If crypto filter returns no results, the coin may not have recent coverage from NS3's monitored sources. This does not improve with higher limit values (limit only controls how far back in time results go). Suggest the user check the coin's official community channels (X/Twitter, Discord, Telegram) for project-specific updates.
News type filter (single value): Returns only articles of a specific type.
# Level 2 articles only
curl -s "https://api.ns3.ai/feed/news-data?lang=en&newsType=important&limit=20"
Exclude levels (multi): Removes articles at specific importance levels.
Combined filters: Multiple parameters can be combined.
# Important BTC news only (recommended for "BTC important news")
curl -s "https://api.ns3.ai/feed/news-data?lang=en&crypto=BTC&excludeLevels=3,4&limit=20"# BTC news excluding routine items

Response (RSS XML, up to 100 items. Use limit to reduce.)
<mentionedCoins>: Related token symbols, CSV (e.g., BTC,ETH,SOL). May be empty.
<storyKey>: Event clustering identifier. JSON object with four fields: entity (array of 1–2 primary actors), action (core action category from a fixed list), figure (array of 1–2 normalized numeric values, or ["none"]), and keywords (array of 3–8 discovery tags for topic matching and cross-article discovery). entity, action, and figure together form the clustering key — articles that share the same actor, action, and key figure describe the same event. keywords is a separate discovery tag array and is not used for clustering. Level 1–4 only. Example: {"entity":["sec"],"action":"ruling","figure":["125m"],"keywords":["sec","ripple","xrp","ruling"]}
<insight>: Full AI analysis in markdown. Split on ## to extract sections. Level 1-3 = 5 sections. Level 4 = Key Point only.
<pubDate>: RFC 822 (e.g., Sat, 07 Mar 2026 15:04:45 GMT)
<link>: NS3 AI Insight page URL
<guid>: Unique item ID (use for deduplication)
<media:content>: Preview image URL (may be missing; use fallback image)
The 10 most important stories from the past 24 hours, clustered so that multiple reports about the same event become one story. Stories are ranked by importance level first. Within the same level, a weighted impact score combines per-article impact with coverage breadth and recency of reporting, so that fresh reports are not diluted by older coverage. Ties are broken by directional signal strength and how directly the event reaches crypto markets. Only Level 1-2 articles are used. Updated every hour on the hour.
The past 24 hours of important news (Level 1-2) reconstructed into a structured narrative briefing. This is not a list of headlines. It is a desk brief that explains what happened and why it matters. Updated every hour on the hour. Returns only the latest single briefing.
Lightest feed: ~2,000 tokens. Best for "catch me up" and "morning briefing" requests.
No filter parameters. lang is the only parameter. Returns 1 item.
Response Structure
The entire briefing is in <description> (CDATA-wrapped markdown). Structured with ### headings for up to five sections:
Top Stories: 2-3 most structurally important events. Each story ends with a relative timestamp — "(reported just now)", "(reported N min ago)", "(reported N hours ago)", or "(reported N days ago)" — so readers can judge information freshness. Always included.
Market Trends: Prices, fund flows, market conditions. Each story also carries a relative timestamp. Omitted if no relevant news.
Regulation & Policy: Regulatory, policy, legal developments. Omitted if no relevant news.
Institutional Updates: Institutional actions, ETFs, market structure changes. Omitted if no relevant news.
What to Watch: Conditional action guidance. "If X happens, then Y is a signal to..." Always included.
Category routing: The briefing consolidates topics into the five sections above. Macro and geopolitical events, as well as security incidents, are routed into Market Trends. Exchange and venue operations are routed into Institutional Updates. Market outlook pieces and general-interest articles do not appear in dedicated category sections — they surface through Top News when they rank high enough.
Fact boundary: Top Stories and category sections use only facts from input articles. No new facts, causal claims, or predictions are generated. What to Watch is the exception: it provides conditional "If X, then Y" guidance.
Present the full briefing to the user preserving section structure. To extract individual sections, split on ### headings.
Breaking headlines from paid news services (Bloomberg Terminal, Reuters). 1-2 sentence alerts. This is Pipeline B, completely separate from the News Feed (Pipeline A). Different sources, different production process. News Flash breaks first; News Feed follows with in-depth analysis of the same event.
