# market0x

> A marketplace for pricing and trading tokenized locked positions — vote-escrow
> NFTs and .base.eth names — on Base, BNB Smart Chain, HyperEVM and Robinhood Chain. Orders are signed by their
> owner and settle on-chain through Seaport; market0x never takes custody and
> never holds keys. Humans and autonomous agents trade the same orders through
> the same interface.

Fee: 1.00% total, split evenly between buyer and seller. Custody stays with
the owner until a trade fills. market0x is a non-custodial software interface,
not a broker, exchange, or custodian — see https://www.market0x.com/docs#disclosure.

## For agents

The whole marketplace is reachable over the Model Context Protocol. Anything a
person can do on the site, an agent can do over MCP — the web routes and the MCP
tools call the same server-side preparation service, so they cannot drift.

- MCP endpoint (Streamable HTTP): https://www.market0x.com/api/mcp
- Agent card (A2A): https://www.market0x.com/.well-known/agent-card.json
- Integration guide: https://www.market0x.com/agents

Tools (13):
- `list_micro_markets` (read): List the markets this marketplace facilitates — asset, chain, settlement currencies, and fee.
- `get_listings` (read): Active listings and auctions for a market, each with its ask, underlying contents priced at market, and discount — sorted by discount.
- `get_listing_details` (read): Full detail for one order, including a fresh live snapshot of the position's contents.
- `get_recent_trades` (read): Recently filled orders (sales) for a market.
- `get_orders` (read): Orders created by an address — its listings, auctions, and offers.
- `get_owned_positions` (read): Positions an address owns in a market, with per-position listability.
- `prepare_purchase` (prepare): Prepare the non-custodial package to buy a listing or accept an offer — ordered approvals plus Seaport fulfill calldata.
- `prepare_offer` (prepare): Prepare a bid/offer to sign — the Seaport order (EIP-712), the currency approval, and how to submit it.
- `prepare_listing` (prepare): Prepare a sell listing or Dutch auction — verifies ownership and transferability, then returns the NFT approval plus EIP-712 order to sign.
- `prepare_cancel` (prepare): Prepare the on-chain Seaport cancel transaction for an active order (only the offerer can execute it).
- `subscribe_notifications` (action): Subscribe a wallet to push notifications via an HMAC-signed webhook — the agent-native alternative to polling.
- `list_subscriptions` (read): List a wallet's notification subscriptions (webhook URLs redacted to origin).
- `unsubscribe_notifications` (action): Delete a notification subscription.

The server prepares transactions and returns unsigned calldata or EIP-712
payloads. The agent's own wallet signs and submits. There is no key custody at
any point.

## Research

Measured analysis of the vote-escrow venues. Figures are measured on the dates
stated and are not updated in place; each piece states its windows and which
figures are derived.

- [Four Weeks After the Rally: What 19 August Changed for metaDEX Voters](https://www.market0x.com/research/august-19-repricing-metadex-fees): The 19 August rally was followed by the second-biggest week Aerodrome has recorded after a big day. Four epochs later: what held, what did not, and what never moved.
- [Paid to Stay: What the metaDEX Model Pays, and What It Costs](https://www.market0x.com/research/paid-to-stay-metadex-model): Aerodrome sends cash to positions people keep; Uniswap makes its token scarcer. Over the six months to August 2026 it distributed $29m to lockers and issued $49m of new AERO to do it.

## Notes for machine readers

- Figures on this site are measurements with a stated source and date, never
  valuations. Underlying contents are reported as tokens and quantities priced
  at current market via a published formula (https://www.market0x.com/docs#data-sources).
- Positions are live and mutable. Contents are re-read at fill; a listing's
  underlying can change after it is posted.
