How this service works
Retrieves the best market price for a specific token ID and side (bid or ask). Returns the best bid price for BUY side or best ask price for SELL side. <!-- aisa-pricing:start --> Published reference price: $0.012 USD per successful request. Account-specific pricing and final settlement may differ. <!-- aisa-pricing:end -->
Output
Returns a single numeric decimal value representing the best available market price — the best bid if the side is BUY, or the best ask if the side is SELL — for the specified Polymarket outcome token.
Example use cases
Pre-trade price check for outcome token
“Before I place a buy order, what's the best ask price right now on Polymarket for the token with ID 0xabc123? I want to know the current cost to get in.”
Monitor bid price for a sell decision
“Can you check the best bid price for Polymarket token 0xdef456 on the SELL side? I'm thinking of selling my position and want to know what I'd get.”
Automated price tracking for arbitrage alert
“Fetch the current BUY price for Polymarket token 0x789xyz — I want to compare it against another source to see if there's a pricing discrepancy worth acting on.”
Technical details
Endpoint
GEThttps://api.aisa.one/apis/v1/polymarket/price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the best single-side market price (bid or ask) for exactly one Polymarket token. Prefer this over the Midpoint endpoint when you need the actionable order-book price for a specific trade direction rather than the theoretical mid-price. Use the batch Prices endpoint instead if you need prices for multiple tokens simultaneously to save on per-call costs.
Side effects
- Invalid or unknown token_id returns an error or empty result
- Missing required parameters (side or token_id) returns a 400 validation error
- Market may be closed or illiquid, returning no meaningful price
- Enum value for side must be exactly 'BUY' or 'SELL' — any other value will fail
- Transient upstream Polymarket API unavailability may cause 5xx errors
