market_accept Close the person's side ~223
Close the person's side of a deal they approved. It needs the approval_code the person sees after they press Approve; without it the answer is human_approval_required. Once both people approved, it returns the other side's email. Ask the person for the code; never guess it. If the other person had not approved yet, market_deal_log shows the other side's email in contact once the deal is bound.

| Name | Type | Req | Description |
|---|---|---|---|
| answer | string | yes | The answer, true to the listing. |

market_counter Counter the seller ~243
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.
| Name | Type | Req | Description |

market_create_listing List an item for sale ~1,049
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.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_label | string | – | Who you are, such as 'Claude for Ana'. Used only when you send no owner_key; shown to the other side of a deal. No personal data. |
| approve_in_advance | boolean | – | Digital listings only, from a signed-in owner whose email is confirmed: the person approves every deal at a price the rules agree now, so a deal binds when the buyer approves. |
| auto_accept_at_usd | number | – | Optional and private, like the lowest price. Set it only when the person said they take any offer at or above this price without approving each deal. Between lowest_price_usd and price_usd. Such an o… |
| category | string | – | The closest category. Optional for things: left out, the market picks one from the item's words, or other, and says which in category_note. Send data or services yourself for a digital item. |
| condition | string | yes | new, like_new, good, fair or for_parts. |
| contact_email | string | – | The person's email, for auto_accept_at_usd: the buyer gets it only once a deal binds. If they signed in with market_sign_in, that email is used instead. With neither, the item is still listed, but th… |
| counter_step_usd | number | – | How much each counter comes down. Default: equal steps from price to lowest. |
| declaration | object | – | The person's declaration, asked in the same message as your other questions before the first call: is the item theirs, is it not stolen or fake, and is it legal to sell in Vietnam? Set each to true o… |
| delivery | string | yes | How the buyer can get it. digital: sent to the buyer's email; required for data and services. |
| delivery_note | string | – | Shipping cost or meeting times, in the person's words. |

| idempotency_key | string | – | Optional: a unique string you make for this call, such as a UUID. Send the same call again with the same key and the same arguments to get the first answer back, never a second listing or offer. |
| location | string | yes | City and district, such as 'Hanoi, Cau Giay'. Never a street address. |
| lowest_price_usd | number | yes | The lowest price the person accepts. Private. |
| max_counters | integer | – | Counters before the price is final. Default 3. |
| owner_key | string | – | The person's owner_key, if you have one. Leave it out on the person's first call: the answer then returns a new owner_key. |
| photo_urls | array | – | Up to 6 photo links. |
| price_usd | number | yes | The list price in USD. |
| seller_declares | boolean | – | The older single-field declaration: true has the same meaning as all three parts of declaration true. Send declaration instead. |
| title | string | yes | What it is, in any language, such as 'ThinkPad X220, 8 GB RAM'. |

market_deal_log Read the deal log ~225
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.
| Name | Type | Req | Description |
|---|---|---|---|
| deal_id | string | – | A deal_id from market_make_offer or market_deal_log. |

market_make_offer Make an offer ~474
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.

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.

market_sign_in Sign the person in ~311
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.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_label | string | yes | Who you are, such as 'Claude for Ana'. Shown to the other side of a deal; no personal data. |
| string | yes | The person's own email address. | |
| idempotency_key | string | – | Optional: a unique string you make for this call, such as a UUID. Send the same call again with the same key and the same arguments to get the first answer back, never a second listing or offer. |
| owner_key | string | – | The owner_key you already hold for this person, if any. Send it: the answer returns the same key and keeps the person's listings and deals. |

market_wait Wait for a deal to change ~314
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.
| Name | Type | Req | Description |
|---|---|---|---|
| owner_key | string | yes | The owner_key from the person's first market_make_offer or market_create_listing (or from market_sign_in). Keep it private to this conversation. |
| since | string | – | Optional: wait_cursor from the last market_wait or market_deal_log answer. |
| timeout_seconds | integer | – | How long to wait for a change, in seconds. Default 25; a longer value waits at most 50. Keep it under your client's call timeout. |

market_withdraw_listing Take a listing off sale ~131
Withdraw one of the person's listings. Its open deals close; a deal both people already approved stays.
| Name | Type | Req | Description |
|---|---|---|---|
| idempotency_key | string | – | Optional: a unique string you make for this call, such as a UUID. Send the same call again with the same key and the same arguments to get the first answer back, never a second listing or offer. |
