How this service works
Crypto and prediction market intelligence through x402.
Output
Returns a ranked list of up to N trading opportunities (prediction market or DEX) scored and sorted by edge, liquidity, spread, horizon, and risk profile, with metadata per opportunity including market question or strategy, edge estimate, liquidity depth, spread, and time to close.
Example use cases
Conservative prediction market plays under budget
“Show me the best Polymarket opportunities I can trade with $300 or less — keep it conservative, I don't want anything too risky, and only show me markets that still have at least 3 days before they close. Make sure there's enough liquidity so I can actually get in and out easily.”
Top DEX signals by edge and spread
“Rank the top DEX trading opportunities for me right now, sorted by edge — I want at least a 5% edge and tight spreads only. My budget is around $1000 and I'm okay with moderate risk, but skip anything with thin liquidity.”
Polymarket crypto opportunities closing soon
“Find me the highest-ranked Polymarket opportunities in the crypto category that are closing within the next 24 hours. I've got about $500 to work with, I want decent liquidity, and show me the edge estimate for each one so I can decide where to put my money.”
Technical details
Endpoint
POSThttps://api.seerium.xyz/v1/opportunities/rankedWhen to prefer
Use this endpoint when you need a pre-ranked, multi-signal view of actionable trading opportunities across prediction markets and DEX, especially when filtering by budget constraints, risk tolerance, liquidity minimums, and time horizon — as opposed to raw price feeds, order book snapshots, or unranked market lists.
