How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object containing the total result count, a list of news articles, the list of sources, a timestamp, the applied token filter, total number of articles fetched upstream, and a sentiment summary object breaking down article sentiment across the filtered set.
Example use cases
Token-specific news monitoring
“Fetch the latest 30 news articles about Ethereum and summarize the overall sentiment for me.”
Broad crypto market news digest
“Give me the top 50 most recent crypto news articles across all tokens — I want a broad overview of what's happening in the market right now.”
Solana sentiment check before trade
“What's the current news sentiment around SOL? Pull the latest articles mentioning Solana so I can gauge the mood before making a decision.”

Endpoint
GEThttps://klymax402.com/api/crypto-news/api/newsWhen to prefer
Choose this endpoint when you need aggregated crypto news with built-in sentiment analysis and optional token-level filtering in a single call, without managing multiple news API keys. Ideal for agents that need to surface market sentiment or recent headlines for a specific cryptocurrency like BTC, ETH, or SOL as part of a broader financial workflow.
Side effects
- Invalid or unrecognized token symbol returns empty articles array
- limit parameter exceeding 100 may be clamped or rejected
- Payment failure (402) if USDC balance on Base is insufficient
- Upstream news source outage may return empty or stale results
- Missing required input object structure returns schema validation error
