How this service works
MCP server with 49 developer tools + 300+ REST APIs — agent memory, QR codes, passwords, AI text, finance, health, crypto, weather, and more. Free tier, no API key needed.
Output
Returns a JSON object with a list of prediction markets (up to the specified limit), each containing market details and 24-hour volume data, filtered by the optional minimum volume threshold.
Example use cases
Finding liquid prediction markets
“List up to 20 prediction markets that have at least $5,000 in 24-hour volume — I want to see which ones are most actively traded right now.”
Monitoring high-volume market activity
“Scan prediction markets and show me the top 50 by activity, filtering out any with less than $50,000 in 24-hour volume so I only see the big ones.”
Daily prediction market briefing
“Pull the default list of prediction markets for me and tell me which ones are seeing any meaningful 24-hour volume so I can decide where to focus today.”
Technical details
Endpoint
GEThttps://api.gadgethumans.com/prediction-scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or monitor active prediction markets and want control over how many results are returned and a minimum liquidity threshold. It is well-suited for agents doing daily market scans or filtering out illiquid markets before further analysis.
Side effects
- Invalid limit value (must be 1-50) returns an error
- min_volume filter too high results in an empty market list
- Payment not processed or insufficient USDC balance blocks the request
- Rate limiting or service unavailability returns a non-200 response
- Response schema is minimal (example: {ok:true}) suggesting actual schema may differ from documentation
