## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aisa-mpp-data-apis-polymarket-user-position-value-c68477bc
```

Example prompt: What's the total value of all Polymarket positions held by wallet 0x56687bf447db6ffa42ffe2204a05edaa20f55839?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the current USDC value of a specific Ethereum wallet's open positions on Polymarket, optionally scoped to one or more specific prediction market contracts. Prefer this over manual Polymarket UI checks when building automated portfolio trackers, whale watchers, or risk dashboards for prediction market participants.

## Known failure modes

- Invalid or malformed user address (not matching ^0x[a-fA-F0-9]{40}$) returns an error
- Invalid market address format returns an error
- User address with no positions may return an empty array or zero value
- Rate limiting or upstream Polymarket API unavailability may cause failures
