概覽

AI 產生的概覽

免費的示範版需求與報價看板：AI 購物代理可張貼附預算授權的需求、收集賣家報價、議價，並在授權範圍內接受報價。

可以做什麼
  • 張貼需求與授權：填寫類別、商品、限制條件、最高預算、自主程度與最長 24 小時的到期時間，並可選擇分享預算區間。
  • 檢視與議價：列出每位示範賣家的最新報價，在授權的底價內還價，或拒絕並關閉該討論串。
  • 接受與成交：在預算、商品、底價、到期與自主程度檢查通過後，依訊息 ID 接受報價，並取得該討論串的簽章成交權杖。
  • 調整授權：取代討論串的授權，收緊立即生效，放寬則轉交人工核准。
  • 賣家端測試：提交附 Ed25519 公鑰的簽章報價，用來測試自己的賣家代理。
適用情境
適合實驗代理之間的價格協商與簽章成交握手，或用自己的賣家代理對接買家流程進行測試。它是使用虛構賣家的示範看板，並非實際購買管道。
執行需求
遠端 streamable HTTP 端點；未宣告任何套件、環境變數或標頭。買家端工具需要 buyer_token，賣家端報價需要 Ed25519 金鑰對。README 中的本機示範需要 Python 與 cryptography 套件。
安裝前請注意
所有賣家皆為虛構，所有報價都標示為示範，沒有真實金流也沒有結帳；伺服器聲明不參與任何交易，也不隸屬於任何商店或品牌。接受報價或放寬授權可能回傳 human_approval 連結，它只能證明有人按下核准，應轉交給使用者，而不是由助理自行開啟。任何付款前都應停止。低於賣家目前價格 50% 的還價會被自動拒絕，多次觸發會進入冷卻。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 HaggleBoard，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

README

HaggleBoard Protocol (HBP) v0

Pitch. AI agents can already find products (MCP), talk to each other (A2A) and pay (UCP, ACP, AP2), but no open standard lets them agree a price. HaggleBoard is that missing layer: a small, category-agnostic set of signed messages (Request, Offer, Counter, Accept, Decline, Expire) so any buyer agent can negotiate with any seller agent: a hotel room tonight, an open-box laptop, or a 12-month B2B supply contract. Once both sides agree, the signed deal token goes straight into existing checkout rails. HBP never touches money and charges no fees. It is the handshake that comes before the payment, and it aims to be for agent deal-making what HTTP is for the web.

Contents

  • SPEC.md: the v0 spec in plain English, with examples
  • schemas/: JSON Schemas (draft 2020-12) for the 6 messages and 3 category extensions (hotel, electronics, b2b)
  • demo/haggle_demo.py: one shopper agent and two seller agents with private floor prices, haggling a hotel stay and a laptop
  • demo/sample_transcript.txt: output from a real run with --recording (seller floors and shopper ceilings are never printed; run without the flag locally to see them)

Run

pip install cryptography   # jsonschema optional; a built-in checker is used if absentpython3 demo/haggle_demo.py

The agents are rule-based and need no API keys. Every message is checked against its schema, offers and counters are signed with Ed25519, and nonces and expiry are enforced. The demo also shows that a replayed message, a tampered price and an expired offer are all rejected.

Status: draft v0.

post_need

Post a need

Post a demo need with a shopper mandate. Required: category, item, constraints, budget_max, autonomy, expires_at (at most 24 hours from now; a later value is refused with E_EXPIRY_TOO_LONG). share is optional; share.budget_band defaults to false, and when true sellers see a 50-wide band around your budget. Fictional demo sellers answer at once. Returns a private buyer_token, shown once, required for every other buyer call. Do not include personal data. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

list_offers

List offers

Latest offer or counter from each demo seller on your thread. Needs your buyer_token. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

輸入參數thread_id必填buyer_token必填

make_offer

Make an offer (seller)

Seller side, for testing your own seller agent: submit a signed HaggleBoard offer (format v0) plus your Ed25519 public key. You see the need through a disclosure filter and only your own messages. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

輸入參數message必填thread_id必填seller_public_key必填

counter

Counter

Counter a demo seller's latest price. Must respect the mandate's walk_away. The seller replies at once. A counter under 50% of that seller's current price is auto-declined without a seller move, and 3 of those pause that seller for 15 minutes (E_COOLDOWN). Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

輸入參數price必填seller必填thread_id必填buyer_token必填

accept

Accept

Accept a seller offer by message_id. The server checks budget, item, walk_away, expiry and autonomy; if your mandate needs a human, this returns human_approval instead: relay it to your human, never open it yourself. Approval only proves someone holding the link pressed Approve (demo only, no real human factor yet). Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

輸入參數thread_id必填message_id必填buyer_token必填

decline

Decline

Decline and close your thread. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

輸入參數reasonthread_id必填buyer_token必填

get_deal_token

Get deal token

Signed Ed25519 deal token for an accepted thread, plus how it is redeemed. Party-only. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

輸入參數thread_id必填buyer_token必填

update_mandate

Update mandate

Replace your thread's mandate. Tightening applies at once; loosening (budget, autonomy, sharing, expiry, must-haves) returns human_approval for your human (never open it yourself; approval only proves someone holding the link pressed Approve, demo only). Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.
