How this service works
Crypto and prediction market intelligence through x402.
Output
Returns a detailed analysis object for one or more Polymarket rewards markets, including order book depth metrics, slippage estimates, quote band ranges, recent trade prints, spread eligibility against rewardsMaxSpread, and signals useful for optimizing liquidity-provider reward strategies.
Example use cases
Evaluating reward spread eligibility
“Check the Polymarket rewards lab analysis for marketId '0xdef456' with clobTokenIds ['333','444'] and a rewardsMaxSpread of 0.05 — I want to know if the current order book is tight enough to qualify for maker rewards.”
Comparing order book depth across markets
“Run the rewards lab on these two Polymarket markets — marketIds '0xaaa111' and '0xbbb222' with their respective clobTokenIds — so I can see which one has better depth and less slippage for liquidity provision.”
Optimizing quote bands for LP strategy
“I'm market-making on Polymarket and want to fine-tune my quotes. Analyze the rewards lab data for conditionId '0xccc333' with clobTokenIds ['555','666'] and show me the recent prints and recommended quote bands.”
Technical details
Endpoint
POSThttps://api.seerium.xyz/v1/prediction/rewards/labWhen to prefer
Choose this endpoint when you need deep liquidity and reward-eligibility analysis for a specific Polymarket market — particularly when deciding whether to provide liquidity to earn maker rewards. It goes beyond simple price lookups by combining order book depth, slippage, and quote band data in one call. Prefer it over generic market data endpoints when your goal is Polymarket LP reward optimization rather than just price or volume checks.

- Invalid or non-existent marketId returns empty or error response
- Payment of 0.1 USDC not included triggers a 402 Payment Required
- Market no longer active may return stale or empty book data
- Malformed clobTokenIds array returns schema validation error
