## Tools

### Cancel All Open Orders

**Slug:** `POLYMARKET_CANCEL_ALL_OPEN_ORDERS`

Cancel all authenticated Polymarket US open orders, optionally scoped to specific market slugs. This is broad and destructive for remaining open quantities; omit slugs only when the user clearly asks to cancel every open order. Already executed fills and positions remain, so verify open orders afterward when confirmation matters.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `slugs` | array | No | Optional market slugs to restrict cancellation to. Omit only when the user explicitly wants every open order canceled across the account. |

#### Output

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `data` | string | Yes | Data from the action execution |
| `error` | string | No | Error if any occurred during the execution of the action |
| `successful` | boolean | Yes | Whether or not the action execution was successful or not |

### Cancel Multiple Orders

**Slug:** `POLYMARKET_CANCEL_MULTIPLE_ORDERS`

Cancel up to 20 Polymarket US open orders in one request. Use only when the user explicitly asks to cancel the batch. Cancellation removes remaining open quantity but does not undo fills or positions, and batch responses can require per-order follow-up reads to verify final state.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `orders` | array | Yes | One to 20 open orders to cancel in a single batch. The request is destructive for remaining open quantities; confirm each order's final state when partial success or unknown order IDs matter. |

#### Output

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `data` | string | Yes | Data from the action execution |
| `error` | string | No | Error if any occurred during the execution of the action |
| `successful` | boolean | Yes | Whether or not the action execution was successful or not |

### Cancel Order

**Slug:** `POLYMARKET_CANCEL_ORDER`

Cancel one Polymarket US open order by exchange-assigned order ID. This is a destructive mutation of the remaining open quantity and should only be used when the user explicitly asks to cancel. Already executed fills and resulting positions remain; confirm order state afterward when precision matters.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `orderId` | string | Yes | Exchange-assigned open order ID to cancel. Canceling removes any remaining unfilled quantity but does not reverse fills that already executed. |
| `marketSlug` | string | Yes | Market slug that contains the order being canceled. |

#### Output

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `data` | string | Yes | Data from the action execution |
| `error` | string | No | Error if any occurred during the execution of the action |
| `successful` | boolean | Yes | Whether or not the action execution was successful or not |

### Close Position Order

**Slug:** `POLYMARKET_CLOSE_POSITION_ORDER`

Create a live Polymarket US order intended to close an existing position in one market. Use only when the user explicitly asks to close that position. This can trade immediately, leave residual exposure if not fully filled, or be rejected for market, liquidity, risk, or funding checks; inspect the returned order state before confirming the position is closed.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `marketSlug` | string | Yes | Market slug of the existing position to close. Use only for the market the user has identified. |
| `maxBlockTime` | string | No | Maximum block time in seconds when synchronousExecution is true. |
| `slippageTolerance` | object | No | Slippage tolerance for the close-position order. Wider tolerance can increase fill probability but may close at a worse price. |
| `manualOrderIndicator` | string ("MANUAL_ORDER_INDICATOR_MANUAL" | "MANUAL_ORDER_INDICATOR_AUTOMATIC") | No | Whether the close-position order is manual or automatic for audit and routing purposes. |
| `synchronousExecution` | boolean | No | Whether to block until the close-position order reaches a final state. If false or omitted, read the order later to confirm fills or rejection. |

#### Output

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `data` | string | Yes | Data from the action execution |
| `error` | string | No | Error if any occurred during the execution of the action |
| `successful` | boolean | Yes | Whether or not the action execution was successful or not |

### Create Multiple Orders

**Slug:** `POLYMARKET_CREATE_MULTIPLE_ORDERS`

Submit up to 20 live Polymarket US orders in one request. Use only after the user explicitly asks to place the batch and, when practical, after previewing the same orders. This mutating action can consume buying power and create exposure across multiple markets; read per-order statuses because a batch can contain accepted, filled, and rejected orders.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `orders` | array | Yes | One to 20 live orders to submit in a single batch. Preview each order first when possible; accepted orders can reserve funds, fill, or create market exposure, and individual orders may be rejected. |

| `data` | string | Yes | Data from the action execution |
| `error` | string | No | Error if any occurred during the execution of the action |
| `successful` | boolean | Yes | Whether or not the action execution was successful or not |

### Create Order

**Slug:** `POLYMARKET_CREATE_ORDER`

Submit one live Polymarket US order. Use Preview Order first unless the user has already reviewed the exact order details. This mutating action can reserve buying power, fill immediately, or create real market exposure; the API may also reject the order for funding, price, market, or risk checks, so inspect the returned status before confirming placement.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `order` | object | Yes | Live order to submit after previewing the same parameters with Preview Order. Either intent or outcomeSide plus action must identify the side; accepted orders can immediately reserve funds, fill, or create market exposure. |

#### Input Parameters

| Parameter | Type | Required | Description |

### List Markets

**Slug:** `POLYMARKET_LIST_MARKETS`

Discover Polymarket US markets from the public gateway API. Use this action when an agent needs candidate market slugs or IDs before reading market details, order books, best bid/offer, or preparing orders. Practical guidance for agents: - For currently tradable candidates, start with active=true, closed=false, and archived=false, then paginate with limit and offset. - Pass numeric market IDs in id and market slugs in slug; do not mix the two identifier types. - Discovery results are not a substitute for live pricing. Before quoting, previewing, or placing an order, read Get Market BBO for top-of-book or Get Market Book for depth. - This read-only discovery action does not require Polymarket API key auth.

#### Input Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `id` | array | No | Numeric market IDs to fetch. Do not pass market slugs here; use the slug filter for known market slugs. |
| `slug` | array | No | Known market slugs from Polymarket URLs or discovery responses. Do not pass numeric market IDs. |
| `limit` | integer | No | Maximum number of markets to return for this page. Use with offset to page through discovery results; the API supports up to 100 per call. |
| `active` | boolean | No | Filter by whether the market is currently active. For tradable discovery, commonly combine active=true with closed=false and archived=false. |
| `closed` | boolean | No | Filter by whether the market is closed. Set closed=false before preparing orders; set closed=true for historical or settlement research. |
| `offset` | integer | No | Zero-based number of markets to skip. Increase by limit for subsequent pages when scanning many markets. |
| `tagIds` | array | No | Numeric tag IDs to include. Use list/search discovery first if the caller only has a readable tag slug. |
| `orderBy` | array | No | Response fields to sort by, such as updatedAt, startDate, endDate, volumeNum, liquidity, or closedTime. Pass as an array even for one field. |
| `archived` | boolean | No | Filter by whether the market is archived. Archived markets are usually not suitable for current trading workflows. |
| `categories` | array | No | Market categories to include, such as sports. Use broad categories first, then narrow with marketTypes, sportsMarketTypes, or tagIds. |
| `marketTypes` | array | No | Market type strings to include. For sports, values commonly identify market families such as moneyline, spread, totals, props, or futures. |
| `includeHidden` | boolean | No | Whether to include hidden markets. Leave false or omit for normal agentic discovery; hidden markets may be incomplete or not intended for user-facing results. |
| `orderDirection` | string ("asc" | "desc") | No | Sort direction for orderBy. Use desc for newest or highest values first, asc for oldest or lowest first. |
| `sportsMarketTypes` | array | No | Structured sports market type enum values. Use this instead of free-form marketTypes when the caller knows the sports market family. |

#### Input Parameters

| Parameter | Type | Required | Description |
