Builder example

REST API and MCP access

Agent-ready

REST request

GET https://stocknews.ai/api/news?sentimentRating=bullish,verybullish&symbol=AAPL&limit=10

MCP server URI

Ask your MCP-connected agent: Find bullish AAPL news with source URLs and explain why it matters.

What you get

Structured news signals for agents.

Sentiment is useful when it is paired with event context, source quality, ticker relevance, and reasoning.

Best for apps that need sentiment-filtered stock news without building their own scraping and classification pipeline.

Use sentiment alongside importance, relevance, event type, source count, and startPrice instead of treating sentiment alone as the signal.

Sentiment rating

Filter and rank by verybullish, bullish, neutral, bearish, and verybearish labels.

Numeric scoring

Use sentimentScore, importanceScore, relevanceScore, confidence, and noveltyScore when available.

Plain-English reasoning

Read sentimentReasoning and stockImpactReasoning to understand why a signal may matter.

Original URLs

Keep traceability with url, source, sourcesJson[].sourceUrl, sourceCount, and published timestamps.

How it works

From financial news to AI decisions.

Step 1

Request

Ask for sentiment-filtered news by symbol, source, eventName, or hot/market view.

Step 2

Inspect

Use summary, sentimentRating, scores, reasoning, source URLs, and startPrice to understand the signal.

Step 3

Apply

Send the signal into an AI agent, dashboard, alerting workflow, or research notebook.

FAQ

Common builder questions.

Is sentiment based only on the headline?

No. StockNews.AI analyzes article content and event context, then returns a sentiment rating and reasoning.

Can I combine sentiment with event filters?

Yes. You can combine sentimentRating with eventName, symbol, source, type, and limit parameters.

Why include source URLs with sentiment?

Source URLs help users and agents verify the underlying article before trusting or acting on a signal.
