How this service works
Retrieves last trade prices for multiple token IDs using query parameters. Maximum 500 token IDs can be requested per call. <!-- 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 an array of objects, one per token ID, each containing the token_id, the last trade price as a decimal string (e.g. '0.45'), and the side of the last trade ('BUY' or 'SELL').
Example use cases
Track election market token prices
“Can you fetch the last traded prices for these three Polymarket election outcome tokens — 0xabc123def456, 0xdef789abc012, 0x123456789abc — and tell me whether each last traded as a buy or sell?”
Bulk portfolio price check
“I hold positions in 20 Polymarket contracts. Here are all their token IDs — can you pull the most recent trade price and direction for each one so I can see where my portfolio stands?”
Arbitrage signal monitoring
“I need to quickly check the last trade prices and trade sides for these 50 Polymarket token IDs to spot any pricing discrepancies between correlated markets.”
Technical details
Endpoint
GEThttps://api.aisa.one/apis/v1/polymarket/last-trades-prices?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need last-trade price snapshots for one or many Polymarket tokens in a single call, especially for bulk lookups of up to 500 tokens. Prefer this over order-book endpoints when you only need the most recent executed price and trade direction rather than the full bid/ask spread.
Side effects
- Requesting more than 500 token IDs in a single call results in an error
- Invalid or malformed token IDs return no results or an error for those entries
- Token IDs with no trade history may return empty or missing entries
- Network or upstream Polymarket API errors may cause partial or empty responses
