PredictionToolkit
What is Adanos Market Sentiment API?
Ticker discovery covers stocks and ETFs, with sector and country aggregates for broader research. Buzz measures activity without choosing a bullish direction; sentiment and bullish/bearish proportions are separate fields. Read the underlying contract questions, liquidity and participation before treating a ticker aggregate as a view on the stock.
Polymarket data refreshes approximately hourly. Discovery and ticker queries use inclusive from/to UTC dates, with a documented default lookback of 7 days when no window is supplied. Trend compares the current 3 UTC days with the preceding 3. Representative historical markets are not exact retained evidence; Professional snapshots are relevant when a reproducible market-level record is required.
Who it is for
- Developers building stock-event research dashboards.
- Quants comparing social attention with prediction-market activity.
- Researchers needing sector and country aggregates.

Workflows with Adanos Market Sentiment API
Research a ticker
Retrieve its activity, inspect representative contracts and check quality flags before interpreting the aggregate.
Compare attention sources
Apply the same date window to Polymarket and social APIs so differences do not merely reflect different periods.
Keep an evidence archive
When a historical row must be recoverable, build your record from saved raw snapshots. The representative top-market list offers examples, not a replacement for those rows.
Reproduce a comparison
A reproducible comparison needs more than matched ticker labels. Query Polymarket, social and news data with the same inclusive UTC interval, and store each response with its retrieval time. Treat current_market_count as a current-state field, not a count of markets active during that interval; retain Professional snapshots when market-level evidence is needed.

Frequently asked questions about Adanos Market Sentiment API
Does a key cover all sources?
Yes. A subscription key covers the 5 APIs, and endpoint usage shares the plan quota.
Can Hobby power a sold product?
A business integration or resale requires Professional's commercial-use rights. Hobby is limited to personal trading, academic research and side projects. There is also an application route for qualifying education and nonprofit users seeking free non-commercial access; eligibility is not an automatic grant.
How fresh is Polymarket data?
It is refreshed approximately hourly.
What happens for an unknown ticker?
The documented response can be HTTP 200 with found=false. Inspect the response fields rather than treating HTTP success as a found ticker.
Does a high Buzz Score mean a bullish forecast?
Activity is what the 0–100 Buzz Score ranks; its level does not supply a bullish probability. For direction, use the separate sentiment and bullish/bearish proportions, then read the contracts to see what the ticker aggregate actually represents.
