How this service works
Real-time crypto sentiment for a ticker symbol (e.g. BTC, ETH, SOL) from 9 crypto news RSS outlets (CoinDesk, Cointelegraph, Decrypt, Bitcoin Magazine, The Block, CryptoSlate, NewsBTC, CryptoPotato, The Defiant) and the Fear & Greed Index. Headlines from the last 72h, weighted toward the newest. Returns a bullish/bearish/neutral label (or 'insufficient recent news'), score, sample size and the top 5 headlines behind it (title, link) as JSON. Path param: symbol, e.g. /sentiment/BTC.
Output
A JSON object containing the ticker symbol, an overall sentiment label (bullish/bearish/neutral), a numeric sentiment score, and a per-source breakdown showing individual sentiment readings from Reddit, CoinDesk, Cointelegraph, Decrypt, and the Fear & Greed Index.
Example use cases
Trading bot market signal check
“Before executing my BTC trade, check the current sentiment — is it bullish, bearish, or neutral? Pull from Reddit, crypto news, and the Fear and Greed Index and give me a breakdown by source.”
Ethereum investment research
“I'm researching whether to buy ETH this week — what's the aggregated sentiment score across crypto news sites and Reddit right now, and is the overall signal bullish or bearish?”
Multi-coin sentiment dashboard
“Give me a sentiment snapshot for BTC, ETH, and SOL — for each one tell me whether the market is bullish, bearish, or neutral based on recent news and social media.”
Technical details
Endpoint
GEThttps://crypto-sentiment-x402.onrender.com/sentiment/:symbol?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-source, aggregated crypto sentiment signal combining social media, news outlets, and the Fear & Greed Index in a single call. It is ideal for trading bots, market research agents, or dashboards that need a fast bullish/bearish/neutral classification with per-source transparency, rather than querying each data source individually.
Side effects
- Unknown or unsupported ticker symbol returns an error or empty result
- Reddit or news source APIs temporarily unavailable, causing incomplete aggregation
- Payment not received (402 response) if USDC payment header is missing or invalid
- Rate limiting or timeout on external data sources causing stale or partial data
- Symbol passed in lowercase may not be recognized — requires uppercase (e.g. BTC not btc)
