What are finlight's request and article limits on the free tier?

The free tier includes 5,000 requests per month with delayed article data, and every request can return up to 100 articles. For comparison: marketaux Free allows 100 requests per day with 3 articles per news request and 0 entities per stat request.

Which sources, markets, and languages does finlight cover?

A curated set of finance-relevant publishers rather than the largest possible source count: global wires and financial press in English, plus multilingual coverage including Chinese-language domestic media and Japanese sources. The full live list is in your dashboard under Sources. If you need a source we do not carry: you name the source, we onboard it as part of your contract.

How fast do new articles arrive?

WebSocket and webhook consumers receive an article as soon as finlight ingests it. The one number we publish is internally measured: the raw stream delivers an article on average about 28 seconds before the enriched version of the same article, which is the cost of sentiment and entity enrichment. We do not publish end-to-end publication-to-delivery figures, because those depend on publisher timestamps we do not control.

How much historical news can I query?

About 2 years of history across essentially all sources, on plans that include historical data. Reuters headlines reach back to 2007, headlines only. Historical queries use the same query language as the live stream.

How do I switch from marketaux to finlight?

Port the polling call first: marketaux GET /v1/news/all maps to finlight's article search, as in the code blocks above. Symbol filters become tickers or a ticker: query, entity flags become includeEntities, date windows become from/to. Then remove the poller: register a webhook with the same query, or connect the WebSocket with the same filter, and matching articles are pushed to you instead of fetched by you.

Marketaux Alternative

Switch from polling marketaux to a financial news API that pushes sentiment-scored, entity-tagged articles to you over WebSocket and webhooks, with full article content on content-available sources.

Copy-paste runnable code

Your marketaux polling call, ported

If you poll marketaux's /v1/news/all today, this is the equivalent request against finlight's financial news API. Only the API key is missing.

TypeScript

import { FinlightApi } from 'finlight-client'

const api = new FinlightApi({ apiKey: 'YOUR_API_KEY' })

// Replaces: GET https://api.marketaux.com/v1/news/all?symbols=NVDA,AMD&filter_entities=true
const res = await api.articles.fetchArticles({
  query: 'ticker:NVDA OR ticker:AMD',
  includeEntities: true,
  pageSize: 100,
})

for (const a of res.articles) {
  console.log(a.publishDate, a.sentiment, a.confidence, a.title)
  console.log(a.companies?.map((c) => `${c.ticker} (${c.exchange})`).join(', '))
}

Python

from finlight_client import FinlightApi
from finlight_client.models import ApiConfig, GetArticlesParams

api = FinlightApi(config=ApiConfig(api_key="YOUR_API_KEY"))

# Replaces: GET https://api.marketaux.com/v1/news/all?symbols=NVDA,AMD&filter_entities=true
res = api.articles.fetch_articles(
    params=GetArticlesParams(
        query="ticker:NVDA OR ticker:AMD",
        include_entities=True,
        page_size=100,
    )
)

for a in res["articles"]:
    print(a["publishDate"], a["sentiment"], a["confidence"], a["title"])
    print(", ".join(f"{c['ticker']} ({c['exchange']})" for c in a.get("companies", [])))

Install with npm install finlight-client or pip install finlight-client. The query language supports boolean logic, ticker:, source:, isin:, and exclusions; the same query drives REST, WebSocket, and webhooks.

Webhook proof

The request you stop sending

marketaux's delivery model is REST polling only: no WebSocket, no webhooks, no push delivery appears anywhere on its pricing page or docs. With finlight you register a query once, and when an article matches, this POST arrives at your endpoint:

// POST https://your-endpoint.example.com/finlight
// Signed with HMAC-SHA256 for verification
{
  "title": "Nvidia eyeing up to $3B investment in Blackstone-backed power firm: The Information",
  "link": "https://seekingalpha.com/news/4629648-nvidia-to-fund-3b-in-blackstone-backed-power-firm",
  "source": "seekingalpha.com",
  "publishDate": "2026-08-08T14:52:43.000Z",
  "sentiment": "neutral",
  "confidence": 0.9998843669891357,
  "companies": [{ "ticker": "NVDA", "name": "NVIDIA Corporation", "exchange": "XNAS" }]
}

Deliveries retry automatically with exponential backoff and are signed with HMAC-SHA256. Webhooks are available on plans that include them; see pricing.

Honesty block

When marketaux is the better choice

marketaux claims 200,000+ tracked entities across 80+ global markets and 30+ languages from 5,000+ sources, with a genuinely free tier and a $29 entry plan. If your job is occasionally polling a very wide global entity universe over REST, and push delivery, streaming, and full article content do not matter to you, marketaux does that well for less money. Stay on this page if you need webhooks or WebSocket delivery, full article content, or entity-tagged articles the moment they are ingested.
