Polymarket

Browse prediction markets, inspect books and balances, and manage orders or positions in Polymarket - powered by ClawLink.

Work with Polymarket from chat - browse markets and events, inspect books and balances, and manage orders or positions.

Powered by ClawLink, an integration hub for OpenClaw that handles hosted connection flows and credentials so you don't need to configure Polymarket API access yourself.

Quick start

1. Install the verified ClawLink plugin: openclaw plugins install clawhub:clawlink-plugin
2. Start a fresh OpenClaw chat if the plugin was just installed and ClawLink tools are not visible yet
3. If ClawLink is not configured, call clawlink_begin_pairing
4. Tell the user to open the returned pairing URL, sign in to ClawLink if needed, and approve the device
5. After the user confirms approval, call clawlink_get_pairing_status
6. Tell the user to connect Polymarket at claw-link.dev/dashboard?add=polymarket
7. When the user confirms Polymarket is connected, call clawlink_list_integrations and then clawlink_list_tools with the polymarket integration slug

Setup details

Installing the plugin

If the ClawLink plugin is not installed yet, tell the user to run:

text

openclaw plugins install clawhub:clawlink-plugin

If the current chat started before the plugin was installed and ClawLink tools are still unavailable, tell the user to start a fresh chat so OpenClaw reloads the plugin tool catalog.

Pairing ClawLink

If ClawLink reports that the plugin is not configured, the plugin has not been paired with the user's ClawLink account yet.

1. Call clawlink_begin_pairing.
2. Tell the user to open the returned pairing URL in their browser.
3. The user signs in to ClawLink if needed and approves the OpenClaw device.
4. After the user confirms approval, call clawlink_get_pairing_status to finish local setup.

The resulting device credential is stored locally in OpenClaw's plugin config and is only sent to claw-link.dev. The user should not paste raw credentials into chat.

Connecting Polymarket

Tell the user to open https://claw-link.dev/dashboard?add=polymarket and connect Polymarket there. The page opens the add-connection panel filtered to Polymarket. ClawLink's hosted page runs the Polymarket provider connection flow. When they confirm it is done, call clawlink_list_integrations to verify, then call clawlink_list_tools with integration polymarket.

Using Polymarket tools

ClawLink provides tools dynamically based on what the user has connected. You do not need to know tool names or schemas in advance.

Discovery

1. Call clawlink_list_integrations to confirm Polymarket is connected.
2. Call clawlink_list_tools with integration polymarket.
3. Treat the returned list as the source of truth. Do not guess or assume what tools exist.
4. If the user describes a capability but the exact tool is unclear, call clawlink_search_tools with a short query and integration polymarket.
5. If no Polymarket tools appear, direct the user to https://claw-link.dev/dashboard?add=polymarket.

Execution

1. Call clawlink_describe_tool before using an unfamiliar tool, before any write, or when the request is ambiguous.
2. Use the returned schema, whenToUse, askBefore, safeDefaults, examples, and followups.
3. Prefer market, event, order-book, balance, and position reads before placing or canceling orders.
4. For writes or anything marked as requiring confirmation, call clawlink_preview_tool first, then confirm with the user.
5. Execute with clawlink_call_tool.
6. If it fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

What you can do

Typical Polymarket tasks (actual availability depends on the user's connected account, permissions, scopes, and current ClawLink tool catalog):

• Search markets, events, and subject entities
• Inspect market details, order books, and best bid-offer data
• Review balances, open orders, positions, and activity history
• Preview orders before submitting them
• Create or cancel orders after confirmation

Rules

• Always use ClawLink tools for Polymarket. Do not ask the user for separate Polymarket credentials.
• Do not claim a capability is missing without checking the live ClawLink catalog in the current turn.
• Do not invent slash commands or ask the user to paste raw credentials.
• Ask for confirmation before placing or canceling orders or making any portfolio-affecting action.
• If Polymarket is not connected, direct the user to https://claw-link.dev/dashboard?add=polymarket.
• Never echo or repeat the user's ClawLink credential.
