grimoire-polymarket

You can automate Polymarket order management by querying markets and routing CLOB orders through the Grimoire venue adapter. It supports order placement, cancellation, and bulk-cancel operations for offchain Polygon markets. Return data is available in JSON format.

To place CLOB orders on Polymarket, you need the official polymarket CLI binary installed and environment credentials configured. You must set the POLYMARKET_PRIVATE_KEY variable and optional API keys to authenticate order routing.

Yes, you can retrieve mid_price and token-level CLOB orderbook metrics. The Skill queries Polymarket CLOB data to provide midpoint metrics against USDC, which are useful for strategy inputs and price comparisons.

The adapter supports GTC, GTD, FOK, and FAK order routing through its custom order op. You can preview and commit limit or market orders via the adapter order and market order paths.

You can search for active Polymarket events using the normalized search-markets function or passthrough markets list. This market discovery process returns tradable events and tokens, and supports JSON output for automation workflows.

The Grimoire adapter is limited to offchain Polygon (chain 137) Polymarket markets. It relies on the official polymarket CLI binary and appropriate environment credentials, meaning it cannot interact with markets on other chains.
