Position fields

Field	Type	Description
`wallet`	string	Wallet address holding the position
`token_id`	string	Outcome token ID
`size`	number	Current position size in shares. `0` means the position is fully exited.
`avg_price`	number	Average entry price (0 to 1)
`realized_pnl`	number	Realized profit/loss in USD. Reflects gains/losses from closed portions of the position and from onchain redemptions of resolved markets. Stays `0` for resolved-but-not-yet-redeemed positions; check `redeemable` to detect those.
`unrealized_pnl`	number	Unrealized profit/loss in USD on the remaining open shares. For resolved markets, uses the final settlement price (`1.0` for winners, `0.0` for losers). For live markets, uses the current market price. Returns `0` when `size = 0`. Byte-identical to Polymarket’s `cashPnl` field for any position covered by both.
`current_price`	number \| null	Price used to compute `unrealized_pnl`. `1.0` or `0.0` for resolved markets (derived deterministically from on-chain `payoutNumerators`), the live market price for active markets, and `null` when `size = 0` or no price is available.
`market_status`	string	One of: `"live"` (market still trading), `"resolved-win"` (market resolved, this outcome won), `"resolved-loss"` (market resolved, this outcome lost), or `"closed"` (position fully exited, `size = 0`). A fifth value `"resolved-unknown"` may appear briefly for very old markets while resolution data is catching up. Never `"live"` when `resolved_at` is set.
`won`	boolean \| undefined	Present only on `resolved-win` / `resolved-loss` rows. `true` when this outcome won, `false` when it lost. Derived from on-chain payouts.
`winning_outcome_index`	number \| undefined	Present only on resolved rows. Numeric index of the outcome that won (0 or 1 for binary markets). Pair with `outcome_index` to know whether this row is the winning side.
`outcome_index`	number \| undefined	Numeric index of this row’s outcome within the market’s outcomes array (0 or 1 for binary markets). Stable across the API regardless of how the UI labels the outcome (`Yes`/`No`, team names, etc.). Use this for cross-row joins instead of parsing `outcome` strings.
`total_bought`	number	Total amount bought in USD over the lifetime of the position.
`initial_value`	number \| undefined	Cost basis in USD of the currently held shares (`size × cost_per_share`). Use this if you need the basis number that matches Polymarket `cashPnl` and what users see in the Polymarket UI.
`redeemable`	boolean \| undefined	`true` when the market has resolved and the user can call redeem on the CTF contract to claim payout (or accept loss). Useful for detecting “resolved-but-not-redeemed” positions: filter `market_status = "resolved-loss"` AND `redeemable = true` for unclaimed losses, or `market_status = "resolved-win"` AND `redeemable = true` for unclaimed wins.
`opposite_asset`	string \| undefined	Token ID of the OPPOSITE outcome on the same market (the binary counterpart). Useful for fetching the matching position on the other side without re-resolving the condition.
`market`	string	Market question text
`market_slug`	string	Market URL slug
`outcome`	string	Outcome label (e.g. “Yes”, “No”)
`condition_id`	string	Market condition ID
`image`	string \| null	Market image URL. `null` for some delisted or niche markets.
`event_slug`	string \| null	Parent event slug, distinct from the per-row market `slug`. For multi-market events (NBA games with several lines, election markets with several candidates, FIFA World Cup with one market per team), this is the parent the markets share. For single-market events, equals the market slug. `null` when event metadata is not yet known.
`last_activity`	number \| undefined	Unix timestamp of the wallet’s most recent fill on this position. Present only when querying by `wallet`. Positions with no fill history (e.g. acquired purely via split/merge/redemption) omit this field and sort to the end.
`last_trade_at`	number \| null	Unix seconds. Latest fill on this token across V1 + V2 exchanges. Same data as `last_activity` but always present (`null` instead of omitted) for consistent shape. Use either; `last_trade_at` is preferred for new integrations.
`closed_at`	number \| null	Unix seconds. Latest moment this wallet redeemed any outcome of the market for collateral. `null` when the wallet has not redeemed (open positions, positions sold to zero pre-resolution, or wins held but not yet redeemed).
`resolved_at`	number \| null	Unix seconds. Moment the market was resolved on-chain (when payouts became redeemable). `null` for markets that resolved before polynode began tracking, or for markets that have not yet resolved. Recent markets are fully covered.

Pagination fields

Field	Type	Description
`count`	number	Number of positions in this response
`pagination.limit`	number	Requested page size
`pagination.has_more`	boolean	`true` if more results exist beyond this page
`pagination.pagination_key`	string	Pass this as `pagination_key` in the next request to get the next page

Combined filters

Filter by wallet, market, and status at once.

curl "https://api.polynode.dev/v2/onchain/positions?wallet=0xa973ae12882a1c24a75da7a3b52cb01500b2f639&market_slug=ucl-rma1-bay1-2026-04-07-bay1&status=open&limit=10" \
  -H "x-api-key: YOUR_KEY"

Pagination

Wallet queries return every position for the wallet in a single response (up to 500), sorted by most recent on-chain activity. No pagination needed — request limit=500 and read all results. has_more is always false and no cursor is returned. Wallets with more than 500 lifetime positions are capped at 500. Non-wallet queries (filtering by market_slug, condition_id, token_id, or min_size alone) use cursor-based pagination for iterating through large result sets.

# First page
curl "https://api.polynode.dev/v2/onchain/positions?min_size=100&limit=100" \

# Next page
curl "https://api.polynode.dev/v2/onchain/positions?min_size=100&limit=100&pagination_key=CURSOR_FROM_PREVIOUS" \

Error responses

Status	Response	Condition
400	`{"error": "market_slug not found"}`	Invalid or unknown `market_slug`
400	`{"error": "condition_id not found"}`	Invalid or unknown `condition_id`
401	`{"error": "API key required. Pass via ?key= or x-api-key header."}`	Missing API key
403	`{"error": "V2 endpoints require a paid plan. See polynode.dev/pricing for details."}`	Free tier key
429	`{"error": "Rate limited. N req/s for your tier.", "retryAfterMs": ...}`	Rate limited

Notes

Position data is sourced from onchain settlement records. Every position that was ever opened on Polymarket is included.
The realized_pnl field reflects actual profit/loss from closed portions of the position, including onchain redemptions of resolved markets. For open positions, it reflects any partial closes.
The unrealized_pnl field shows the paper profit/loss on the remaining open shares. For resolved markets, this uses the final settlement price ( $1 for winners,$ 0 for losers). For active markets, the current market price is used.
market_status lets clients distinguish live-tradable positions from positions on resolved markets that the wallet never redeemed. Resolved-and-never-redeemed positions still have size > 0 and will show the correct terminal unrealized_pnl.
Market metadata (market, market_slug, outcome, condition_id, image) is enriched from our index. Very old or delisted markets may not have metadata.
When querying by wallet, the sort key is the timestamp of the most recent fill for each position, not the position’s close date. A position bought months ago and held to resolution (closed only via redemption) will sort by its original buy date.

Verifying parity with Polymarket

Per-position fields on this endpoint match Polymarket’s data-api.polymarket.com/positions byte-for-byte. Anyone can verify directly with the standalone Node script below — no internal access required.

What this proves

If you trust Polymarket’s positions page, you can trust ours — they’re computing the same thing from the same on-chain events. Use this script as ongoing regression coverage in your own integration if PnL accuracy is critical to your product.
