Negotiate several linked issues at once by logrolling — free, no account or key needed.

It concedes on the issues yo

Score how good a deal is against your floor/target — free, no account or key needed. Score a settled package against the exact Pareto frontier — the SNHP leaderboard metric ("dollars left on the table") for YOUR negotiation. Args: issues: one dict per issue: {"name": str, "options": [labels],

The optimal bid when you're bidding in an auction — free, no account or key needed. USE THIS WHEN: you're a bidder and want the bid that maximizes your expected surplus without overpaying. NOT for running an auction (use auction_reserve) or 1:1 haggling (use negotiate). Provide: auction_format ("f

The revenue-optimal reserve price when you're selling — free, no account or key needed. USE THIS WHEN: you're running an auction or sale with multiple bidders and need the floor price (minimum bid you'll accept) that maximizes your expected revenue. NOT for one-on-one haggling (use negotiate for th

Best price plus markdown schedule to clear stock by a deadline — free, no account or key needed. USE THIS WHEN: you must sell a FIXED number of units before a cutoff and demand arrives over time — event tickets, perishable inventory, end-of-life stock.

Match two groups by their rankings so no pair wants to swap — free, no account or key needed. A STABLE matching: USE THIS WHEN you're assigning two sides to each other by mutual preference — interns<->teams, students<->schools, mentors<->mentees — and want a result with no "blocking pair" (no perso

Persistent memory for your agent across sessions — save now, load in any later session. You encrypt before saving; the store holds only ciphertext (blind custody) and signs a receipt over its hash — it cannot read your memory. Saving uses your prepaid wallet; a new key's 50¢ starter credit covers

Load a memory you saved in an earlier session — retrieval is free. Get back an encrypted blob you parked earlier (the blind locker) by its claim `ticket`. Returns {ok, blob_b64, size_bytes, expires_at} — the ciphertext you saved, which only YOU can decrypt. A wrong owner reads as a missing ticket;

Open a $2 receipted negotiation session: deterministic, replayable, every move signed. PAID ($2 once, from your credit balance) — the $2 covers EVERY move of this negotiation (up to 10 moves, 7 days), tuned to the category. A new key's 50¢ starter credit is a taste, not enough for a session — top u

Your next move inside a receipted session (single-issue) — no additional charge (the $2 at session_open covered it). Pass the FULL offer history each time, oldest first. Returns move, exact price, ready-to-send message, and the receipt (why[], context_hash, deterministic compute block).

Multi-issue logrolled advice inside a receipted session — no additional charge. The logrolling tier, the thing the free tool does NOT have. Trade the issues you care less about for the ones you value: issues = [{name, options, my_utility (per option), their_utility (your read of their direction)}];

Close a receipted session and get the signed summary receipt. Optional — sessions also expire on their own — but closing timestamps the outcome, which helps the machine learn real round-counts per category. Returns the `closed` flag AND a signed session-summary receipt (GAUNTLET #4) — moves count,

See what's on the shelf — free, no key needed: prices, predicates, receipt scheme, and your balance. THE STORE: one counter, one prepaid wallet, many slots. One read covers the whole shelf — the commodity slots, the blind locker (agent memory), and the paid receipted-session SKU (folds in what next

Ask for a capability we don't sell yet — free; filings are public and drive what we stock. Two reads in one tool (absorbs the old store_request_status / nextmove_request): pass `request_id` to RE-QUERY a filing's status instead of filing anew — returns {found, request_id, status, status_note, filed
