How this service works
108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.
Output
Returns orderbook imbalance metrics for one or more Polymarket markets, including bid/ask volume skew, imbalance direction (buy-heavy vs sell-heavy), and associated market identifiers (token_id, condition_id). When no specific market is specified, scans a configurable number of active markets (default 10, up to 50).
Example use cases
Spot lopsided prediction market bets
“Check the order book imbalance on Polymarket for the top 15 active markets and flag any where bids or asks are heavily one-sided — I'm looking for trading opportunities.”
Monitor a specific Polymarket contract
“What's the current order book imbalance for Polymarket token ID 0x1234abcd? I want to know if buyers or sellers are dominating right now.”
Pre-trade signal check on known condition
“Before I place a position, pull the orderbook imbalance for Polymarket condition ID 0xdeadbeef and tell me whether there's more buy-side or sell-side pressure.”
Technical details
Endpoint
POSThttps://agenttoll.dev/paid/polymarket/orderbook-imbalanceWhen to prefer
Use this endpoint when you need real-time order flow signals or directional pressure data from Polymarket prediction markets — particularly for pre-trade analysis, market surveillance, or identifying skewed liquidity. Prefer this over general market price feeds when you specifically want to understand buy vs. sell depth imbalance rather than last-traded prices. Best for agents running trading strategies, market monitoring, or research on prediction market microstructure.
Side effects
- Invalid or unknown token_id or condition_id returns an error or empty result
- Polymarket CLOB API unavailable causes request failure
- Requesting more than 50 markets at once is rejected
- Markets with no active orders may return zero or null imbalance values
- Rate limiting may occur under heavy usage
