How this service works
Crypto news sentiment for 24 coins, scored from headlines at 9 crypto news outlets plus the Fear & Greed Index, with the headlines behind each score. Paid per call over x402 in USDC on Base: $0.01 for GET /sentiment/{symbol} and $0.05 for GET /history/{symbol}. Requests for an unsupported coin, a coin with too little recent news, or a history range with no readings are refused and not charged.
Output
A JSON object containing the coin name and symbol, an array of top driver headlines (each with title, source, publication time, sentiment score, source weight, and effect on overall score), a plain-English drivers summary, and an overall_sentiment object with a bullish/bearish/neutral label, 72-hour window average compound score, effective sample size, unweighted compound score, and age of newest headline.
Example use cases
Pre-trade sentiment check for BTC
“Before I place a Bitcoin trade, can you pull the latest sentiment score for BTC and tell me whether the overall signal is bullish or bearish based on recent crypto news?”
Ethereum sentiment dashboard card
“I'm building a dashboard — fetch the current sentiment for ETH, including the top headline drivers and the overall compound score, so I can display a live market mood card.”
Altcoin sentiment comparison
“Can you check the current news sentiment for SOL and ADA and tell me which one has a more positive signal right now, along with the headlines behind each score?”
Technical details
Endpoint
GEThttps://crypto-sentiment-x402.onrender.com/sentiment/%7Bsymbol%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, headline-backed sentiment reading for a specific crypto asset scored across multiple reputable news outlets. It is ideal for pre-trade checks, dashboard widgets, or alerting workflows where you need both a quantitative signal and the underlying evidence (headlines with scores and weights). Prefer it over generic social sentiment tools when editorial crypto news coverage is more relevant than social media chatter, and when you need per-source credibility weighting built in.
Side effects
- Unsupported coin symbol returns an error and no charge is applied
- Coin with insufficient recent news returns an error and no charge
- Invalid or malformed ticker symbol returns a 4xx error
- Service unavailable on Render cold start — brief latency spike or 503 on first request
- Request charged only on successful response; failures are free
