## How to call it through Zero

```

Example prompt: Can you pull up my Polymarket portfolio for wallet 0xABC123 and show me which open positions Quotient still agrees with, flagging anything I should consider selling based on their latest forecasts?

## When to prefer this

Use this endpoint when you need a holistic view of a specific Polymarket wallet's open positions enriched with Quotient's independent intelligence — combining PnL data with forward-looking probability forecasts and trade signals in one call. Prefer this over individual market lookups when the user wants portfolio-level hold/sell guidance rather than analysis of a specific market.

## Known failure modes

- Invalid or unrecognized wallet address returns empty or error response
- Wallet with no open positions returns an empty positions array
- Network timeout from Render-hosted service under cold-start conditions
- size_threshold misconfiguration filters out all positions resulting in empty results
- Payment of 0.001 USDC not provided or rejected, returning 402 error

## How this service works

Wallet-addressed positions across Polymarket, Polymarket perps, Limitless, and Hyperliquid, each prediction-market position joined to Quotient's forecast, signal, and a pricing read against the position's own side. Use this for wallet size, prices, PnL, and Q alignment. venues=all covers every venue; omitting venues keeps the legacy Polymarket-only shape. Kalshi and Polymarket US are absent only for lack of a keyless wallet read, not a limit on Quotient coverage.

## Output

Returns a list of open Polymarket positions for the given wallet, each enriched with Quotient's current probability forecast, published trade signal (YES/NO, conviction), convergence analysis against the position's side, position size, average entry price, current market price, unrealized PnL, and a hold/sell indicator based on whether Quotient still agrees with the position. Optionally includes perpetuals positions.
