How this service works
Send up to 25 crypto headlines or social posts; get JSON per item: sentiment score -1..1, bullish/bearish label, tickers, event type (hack, listing, unlock, regulation, ETF, partnership...), impact, horizon and confidence, plus a batch summary. For trading agents. AI-generated; not financial advice.
Output
A JSON object containing per-item results (sentiment score from -1 to 1, bullish/bearish label, extracted ticker symbols, event type such as hack/listing/unlock/regulation/ETF/partnership, impact score, time horizon, and confidence score) plus an aggregate batch summary across all submitted items.
Example use cases
Real-time trading signal screening
“Here are 20 crypto news headlines from the last hour — can you score each one for sentiment, flag the event type like hack or listing, and tell me which tickers are most impacted so I can prioritize my trades?”
Crypto social post monitoring
“I've pulled 15 tweets about Bitcoin and Ethereum from the last 30 minutes. Can you analyze each one for bullish or bearish sentiment, extract any tickers mentioned, and give me a batch summary of the overall mood?”
Regulatory risk detection
“Scan these 8 crypto news snippets and tell me which ones are about regulation or ETF decisions, what the sentiment is, and how high the market impact is likely to be.”
Technical details
Endpoint
POSThttps://emberagent.uk/p/crypto-news-sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable sentiment and event classification for multiple crypto news items in a single call, especially when you need event-type tagging (hack, listing, unlock, regulation, ETF, partnership) and ticker extraction alongside sentiment — not just a simple positive/negative label. Prefer this over generic sentiment APIs when crypto-domain accuracy and trading-oriented metadata (horizon, impact, confidence) matter.
Side effects
- Input exceeds 25 items — API may reject or truncate the batch
- Malformed input (neither plain text nor valid JSON array) causes parsing error
- Ambiguous or very short headlines may yield low confidence scores
- Non-crypto text submitted may return low-relevance or incorrect event tags
- Rate limiting or payment failure if x402 payment is not properly handled
