`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 listed amount, so treat inexact rows as an upper bound).

`prepare_cancel`Prepare the on-chain Seaport cancel transaction for an active order.

`prepare_listing`Prepare a SELL listing or Dutch auction.

`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. The buyer wallet must hold the offer's outlay (price + its fee share) when it submits; an unfunded offer is rejected (insufficient_balance), and one that later loses its funds or allowance is hidden from the book until they return.

`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 above the quote on a decaying order, never above maxTotalBaseUnits — and Seaport charges the exact interpolated amount at fill. On auctions, prepared.cleanup is an optional post-settlement tx that zeroes the residual allowance. The agent's own wallet signs and submits — this never signs or holds keys.

`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 signed over and the signature is verified on THAT chain, so pass the chain the wallet actually signs on (smart-wallet signatures do not validate cross-chain). Each signed message is SINGLE-USE: resending the same body returns 409 replayed_signature — retry with a fresh timestamp and a new signature. The response includes the webhook HMAC secret ONCE (verify x-market0x-signature = hex(HMAC-SHA256(rawBody, secret))).
