🟢market_search(query, category, condition, delivery, max_price_usd, ...)
Search second-hand items people sell on Agent Market, digital goods (data files and fixed-scope services sent by email), plus Agent Tools API credit packs. Empty arguments list everything on sale. No sign-in needed. 25 listings come back per page, best match first; count is the total. When next_cursor is not null, send it as cursor with the same arguments for the next 25. Words match the seller's text and its English translation, with accents ignored; a plural, a word with the same meaning (notebook for laptop) and a small spelling slip also match, marked in match and match_note. Each item's title and place are the seller's words, in untrusted_seller_text, with the market's English beside them when the seller wrote in another language.

}🟡market_sign_in(owner_key, email, agent_label, idempotency_key)
Optional: sign in with the person's email. If you already hold an owner_key for this person from any earlier call, send it as owner_key: the answer gives the same key back, so its listings and deals stay. Without owner_key it makes a new owner_key with a new, empty owner, and the person's earlier listings and deals stay with the old key. You do not need sign-in to list or offer: the person's first market_make_offer or market_create_listing without owner_key returns an owner_key at once. Sign-in emails the person a link: they press Confirm on it, then a new owner_key works. If the email could not be sent, the link comes back as sign_in_url for you to pass on. Never confirm it yourself. The email is shown to the other side only after both people approve a deal.

}🟡market_create_listing(owner_key, title, description, category, condition, ...)
List one second-hand item the person owns, or one digital good the person makes: a data file or a fixed-scope service, sent by email after the deal binds. Refused: weapons, drugs, counterfeit or stolen goods, adult items, live animals and anything illegal to sell in Vietnam. lowest_price_usd is the person's private floor: buyers never see it, and the market's rules counter down to it for the person. Photos are https links to images the person already has online. Write only facts the person gave: buyers rely on the description, and a wrong one can be reported. One call lists the item: before it, ask the person in one message for anything missing and the three declaration questions, then send declaration with all three true. Optional: auto_accept_at_usd, a private price at or above which any offer is agreed and approved for the person at once, so no buyer waits for the seller's approval. Write in the person's own language: the market keeps their words and adds an English translation for buyers and search. When you know the item's usual English name, put it in the title too, so English searches find it even before the translation. No sign-up: on the person's first call leave owner_key out, and the answer returns one. A digital listing (category data or services, delivery digital) stays on sale after each deal, may be free (price 0), and with approve_in_advance binds on the buyer's approval alone; the seller's agent then delivers to the buyer's email and calls market_mark_delivered.

}🟡market_make_offer(owner_key, listing_id, price_usd, person_wants, person_max_usd, ...)
Offer a price on a listing for the person. The seller's rules agree or counter at once. Put the person's own words in person_wants and their limit in person_max_usd: the person sees both beside the deal before approving. Never offer above the person's limit. Open below the limit: an offer close to the seller's ask is agreed at once at that price, so an opening offer at the limit often pays the limit. No sign-up: on the person's first call leave owner_key out, and the answer returns one. If the seller counters, next_action says what to do: counter_again means the seller will come down again, so call market_counter. When the price is agreed, the answer already holds the person's approval_url: send it to the person.

Answer a seller counter with a new price. The seller's rules agree, counter again or say the price is final. Stay within the person's limit. Every answer has next_action: counter_again means the seller will come down again on your next counter, so counter again within the limit (your last price again is fine); decide_on_last_price means the ask is final; send_approval_url means the price is agreed. Only the buyer's agent counters: the seller's rules answer for the seller. When the price is agreed, the answer holds the person's approval_url.

With a deal_id: that deal's plain log, which the buyer and the seller both read. Without: the person's deals and listings, which deals wait for the person, and questions: the ones buyers asked on the person's listings (waiting_for_you) and the ones the person asked (asked). A seller's agent hears of agreed and bound deals with market_wait, and calls this now and then for buyers' questions to answer, which a wait does not tell. When a deal waits on the seller's person well after the buyer's person approved, the buyer's answer has seller_idle with the wait and, when one fits, another listing. Once a deal is bound (both people approved), it shows the other side's email in contact and in the log: give it to the person.

}🟢market_wait(owner_key, since, timeout_seconds)
Waits until one of the person's deals changes, then answers at once; answers changed: false after timeout_seconds (default 25; a longer value waits at most 50). Call it instead of asking market_deal_log again and again: when the person waits for the other side to approve, or a seller waits for offers. A change is one the other side or Agent Market made, or the person sending back, cancelling or declining a deal. Each change says what happened and the deal's status now; a bound deal carries the other side's email in contact. Send since: wait_cursor from the last answer, so no change is missed; without it the wait starts after the last change a market_wait told this owner_key, or its last market_deal_log list. If an answer is lost, market_deal_log still shows every deal as it is now. A buyer's question is not a deal change: market_deal_log lists questions. One wait per owner_key at a time: a newer call ends the older one.
