Tools as reported by the server

• list_micro_markets
  List the markets this marketplace facilitates (asset, chain, currencies, fee).
• get_listings
  Active listings/auctions for a market. Each row carries the ask and the position's underlying contents priced at current market (published formula: /docs#data-sources), plus discountPct (the difference between them). Sorted by discount percentage, descending.
• get_listing_details
  Full detail for one order including a FRESH live-contents snapshot (principal, claimable rewards, voting/earning power, as_of_block).
• get_recent_trades
  Recently settled sales for a market. `amount` is the EXACT settled total (incl. fee) from the on-chain fill where the indexer recorded it, with `settledAt` the block time and `exact: true`; otherwise it falls back to the listed ask with `exact: false` (a decayed Dutch auction settles BELOW its liste
• prepare_purchase
  Prepare the non-custodial transaction package to BUY a listing (or accept an offer): ordered approvals + Seaport fulfillOrder calldata + a fresh contents snapshot. prepared.summary quotes the CURRENT price (Dutch auctions interpolate, asOf says when); the approval grants approveBaseUnits — slightly
• prepare_offer
  Prepare a BID/offer on a position: returns the Seaport order to sign (EIP-712), the currency approval needed, and how to submit it. The agent reads its Seaport counter, signs, and POSTs the signed order — settlement stays on Seaport.
• prepare_listing
  Prepare a SELL listing or Dutch auction. Verifies the seller OWNS the position and it's transferable (not voted/attached), builds the Seaport order with the Interface fee injected by the server, and returns the one-time NFT approval + EIP-712 typed data to sign. Never signs or holds keys.
• prepare_cancel
  Prepare the on-chain Seaport cancel transaction for an active order. Only the order's offerer can execute it (Seaport enforces msg.sender == offerer), so the calldata is safe to return. After it confirms, POST { txHash } to the confirm endpoint to update the book.
• get_orders
  List orders created by an address (its listings, auctions, offers). Status is reconciled by the background worker — treat as advisory until checked at fill.
• get_owned_positions
  List the positions an address owns in a market, with listability (voted/attached positions can't transfer).
• subscribe_notifications
  Subscribe a wallet to push notifications (order_filled / offer_received / saved_search) via an HMAC-signed webhook — the agent-native alternative to polling. Two-step: call WITHOUT `signature` to get the exact message to sign (EIP-191 personal_sign), then call again WITH the signature. `chainId` is
• list_subscriptions
  List a wallet's notification subscriptions (webhook URLs redacted to origin).
• unsubscribe_notifications
  Delete a notification subscription. Two-step like subscribe_notifications: call without `signature` to get the message to sign. `chainId` is signed over and verified on that chain. Signed messages are single-use.
