Builders of AI agents and retrieval systems

Stock news for AI agents and RAG

An agent that guesses a price move from a headline is not grounded. MarketNewsAPI gives it the article, a neutral summary, the tickers, and the original URL, over MCP or REST.

How does a stock news API help builders of ai agents and retrieval systems?

Pro includes an MCP server with tools to search news, fetch an article, and list trending tickers, so Claude, ChatGPT, and Cursor can cite stock news instead of inventing it. The 7-day trial includes it.

Fit

When this stock news workflow fits

  • Your agent should link the publisher, not paraphrase from memory.
  • You want summaries short enough for a context window.
  • You already use MCP and do not want a custom news tool.

The call

Prompt an agent can answer from the tools

The same article shape on every guide: ticker, type, timestamps, summary, and a link. Press releases include the full text.

How to call it

How do you request stock news for this workflow?

1

Connect MCP

Point the client at the MCP server. Tools include search, latest news, one article, trending tickers, the ticker list, sources, and a market brief. Each article includes a summary and a source link.

2

Or call REST

The same data is on GET /v1/news. Pass q for full-text search and tickers when the user named a symbol.

3

Keep the model honest

Instruct it to quote summary and link url. If the articles do not support a price claim, it should say so. This API is news, not a price feed.

FAQ

Frequently asked questions

Which AI clients work with MarketNewsAPI?
Any MCP client, including Claude, ChatGPT, and Cursor, plus your own agent over REST. OAuth clients send you to sign in and create a key named after the app. Other clients send Authorization Bearer with an API key. Setup steps are on the MCP docs. The server is remote, so you do not install the news tools yourself.
Which plan includes MCP?
Pro includes MCP, at $15 a month or $162 a year. It also includes the WebSocket and REST with no daily cap. The 7-day trial includes MCP, and a card is required. Free keys receive HTTP 403 from the MCP endpoint. Tool calls follow the same 20 requests per second burst limit as REST.
Do MCP answers include the source URL?
Yes. Each article the tools return includes the publisher URL, the title, a short summary, and the tickers. Tell the model to cite that URL and to say when the articles do not explain a move. The tools do not return a quote or a trade signal. Pro, including the 7-day trial, is required. Free keys receive HTTP 403.
