Portfolio Value - Polymarket Data SDK

client.data.core.getValue aggregates a wallet’s exposure in USDC across all or selected markets.

Request

const summary = await client.data.core.getValue(params);

Parameters

Name	Type	Required	Notes
`user`	`string` (address)	✅	Wallet or proxy address.
`market`	`string[]`		Optional condition IDs to scope the calculation.

Response

type UserValue = {
  user: string;
  value: number;
};

The API returns an array, even when querying a single user/market combination.

Usage example

const [summary] = await client.data.core.getValue({
  user: "0x56687bf447db6ffa42ffe2204a05edaa20f55839",
});

console.log(`Total position value: ${summary.value.toFixed(2)} USDC`);

Failure modes

Missing user → validation error.
Invalid condition ID → validation error referencing the offending index.
