compile_offer_policyread-onlyTurn a seller's offer, described in plain words, into negotiation RULES an AI agent cannot break. USE THIS WHEN: you (or the business you act for) sell something where buyers â people or their AI buying agents â ask for discounts, and you want an AI to answer them without giving away margin. Describe the offer: the listed price, the lowest price you'd take for a plain deal, what you'd trade a
draft_negotiation_replyread-onlyDraft the seller's reply to a buyer's message â the offer is decided by the SNHP engine INSIDE the policy. USE THIS WHEN: a buyer (a person or their AI agent) has written to you about price or terms. Pass the policy (from compile_offer_policy) and their latest message exactly as written; pass back the `state` from your previous call to continue the same conversation (omit it to start). `flags`
check_offer_policyread-onlyCheck an edited negotiation policy: returns {ok, policy, issues, summary}. No model call, free. USE THIS WHEN: you changed a policy from compile_offer_policy (a floor, an option, a forbidden combination) and want to know it is valid and what it now allows before using it in draft_negotiation_reply.
verify_deal_receiptread-onlyVerify a signed deal receipt against the seller's own policy: both signatures, that the signing keys are SNHP's own (published at /.well-known/ucp), the policy digest, and every rule re-checked from the package. Returns {ok, problems, checks, signed_by_snhp, signatures}. Free, no model call.
