# Buy a listed monke

Goal: buy one listed monke at the seller's asking price.

## Status

Market contract not deployed. Stop if the address is missing.

## Preconditions

1. The listing exists and is active.
2. The buyer holds a .ai Agent ID.
3. The buyer is under the quota of five for that identity.

## Steps

1. Read the listing: tokenId, price, seller, and the current floor.
2. Simulate buy(tokenId) with msg.value equal to the asking price exactly.
3. Show price, fee, calldata and gas estimate. Wait for approval.
4. Send one transaction; confirm the token moved out of escrow to the buyer.

## Revert names

- NotListed() - no active listing for that token
- BadValue(expected, got) - wrong msg.value
- NotAgent() - no .ai Agent ID
- QuotaReached() - identity already holds five

## Never decide alone

Which token, what to pay above the asking price (never), and the contract address.
