How this service works
Paid on-chain token, wallet, contract and research data over x402 on Base.
Output
Returns a JSON object with a 'query' field set to 'sentiment-aggregate' and a 'result' object containing the aggregated sentiment data computed from the provided sources. The result reflects a combined sentiment signal derived from all input text items and their labeled source types.
Example use cases
Pre-trade market mood check
“Before I make a trade, can you pull the sentiment from these five recent Bitcoin news headlines and tell me if the overall signal is bullish, bearish, or neutral?”
Token research sentiment rollup
“I've got a mix of news articles and social posts about MATIC — can you aggregate all their sentiment into one score so I can see the broader market feeling?”
Automated crypto newsletter sentiment digest
“Every morning I want you to take these ten crypto news items from the past 24 hours and give me an aggregated sentiment reading so I know the general mood before markets open.”
Technical details
Endpoint
POSThttps://coinop.publicvm.com/api/v1/sentiment/aggregate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to combine sentiment signals from multiple heterogeneous text sources (news, social, etc.) into a single aggregate crypto market sentiment score, especially when you want on-chain payment via x402 on Base and are working within a crypto/DeFi agent workflow. Prefer this over single-document sentiment endpoints when you have a batch of inputs and need one unified reading.
Side effects
- Empty or malformed 'sources' array returns an empty result object
- Missing required 'text' or 'type' fields in source items may produce incomplete aggregation
- Payment failure via x402 (insufficient USDC balance) results in 402 response before processing
- Ambiguous or very short text snippets may yield low-confidence or neutral aggregated output
- Rate limits or on-chain congestion may cause timeouts
