Counter a demo seller's latest price. Must respect the mandate's walk_away. The seller replies at once.

Tools (11)

`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.
`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.
`decline`	Decline and close your thread. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.
`get_deal_token`read-only	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.
`get_offers`	Rank matching offers. Pass request_id from post_request, or pass the same fields as a new query against the current snapshot.
`list_offers`read-only	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.
`make_offer`	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.
`post_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.
`post_request`	Post a shopping need (v0: running shoes) and get back offers ranked by stock and price from stores' public product feeds. The need text is stored for up to 30 days; the response includes delete_token once. Don't include personal data. Checkout is on the store's own site; HaggleBoard stops before payment.
`search_products`	Search the public running-shoe snapshot. Each hit links to the store's own product page.
`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.
