How this service works
Polymarket API and prediction market API for agents. Returns prediction market signals, market snapshots, order books, and ranked opportunities.
Output
Returns a structured payload containing Polymarket market snapshots (up to limitSnapshots), order book data, Seerium-generated trading signals with confidence scores, and a ranked list of prediction-market opportunities (up to limitOpportunities) filtered by liquidity, spread, and signal strength.
Example use cases
Identify mispriced election outcome contracts
“Look through Polymarket's election markets right now and find me any prediction contracts that are trading at odds that don't match the Seerium confidence signals — I want to spot the best risk-reward setups before the betting shifts.”
Monitor liquid prediction markets for day trading
“Scan Polymarket and give me the top opportunities in markets with really tight spreads and high volume — I'm looking for prediction contracts I can quickly enter and exit with minimal slippage.”
Find undervalued event outcome bets
“Search Polymarket for events or outcomes where the current odds seem disconnected from what Seerium's signals suggest — show me the highest-confidence trading opportunities ranked by potential edge and liquidity.”
Technical details
Endpoint
GEThttps://api.seerium.xyz/v1/prediction/scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a broad, ranked scan of Polymarket prediction markets with Seerium intelligence layered on top — ideal for discovering high-opportunity trades, monitoring market signals, or ingesting order book context without manually querying individual markets. Prefer over raw Polymarket APIs when you want pre-ranked, signal-enriched output ready for agent consumption.
Side effects
- No liquid markets available — returns empty opportunities list
- Polymarket data feed delay — snapshots may be stale
- Invalid limitSnapshots or limitOpportunities values below minimum of 1 — schema validation error
- Payment not fulfilled (x402) — returns 402 Payment Required before data is served
- Rate limit exceeded — too many calls in a short window
