Tools as reported by the server

• resolve_jurisdiction
  Where is the media bought? Resolve a market (e.g. FR, UK, US, Japan) to one of the 20 markets on the record. UK is the label; GB is accepted.
• resolve_actor
  Who is asking? maker, brand_owner, agency, distributor or retailer_media_team (trade); auditor (read only). The consumer is never the counterparty.
• gate_transaction
  The gate before a handshake: allow or deny for one market and one actor class. Returns a decision_id the handshake tools ask for. A deny is not charged.
• find_makers
  Find the brand: makers on the grocery record of one market (node = one of the 20 markets). segment is taken as a lane where it names one (organic, free-from, plant-based, artisan, origin, premium). Read live from the A2A Grocery door.
• resolve_gtin
  Product record from gtinfetch.ai (signed); hub layer: seat, market, claim, price, availability. Confirm the product is real: is this Global Trade Item Number (GTIN) well-formed, and is it on the grocery record, with its brand and maker. Read live from the A2A Grocery door.
• check_eligibility
  Confirm it is on the shelf: does the grocery record list this GTIN at this banner in this market? No listing, no media pitch. Read live from the A2A Grocery door.
• list_banners
  Pick the banners: the grocery banners of one market with each one's media program (or "none listed") and card status. with_program=true returns only banners with a program listed.
• get_banner_card
  The signed card of one banner and its status (listed · claimed · verified). banner = the banner's slug, id or name.
• list_banner_cards
  The cards of one market, optionally by status (unclaimed, claimed, registered): banner, media program, status and the card's address.
• list_packages
  Match a package: what one banner's media program says it sells, in the program's own words, each tagged onsite, offsite or in-store. Offsite is tagged so it is never taken for a shelf slot. Empty where no program is listed — the agent stops.
• quote_package
  Price it: returns where the banner's own media program publishes its rates or takes an enquiry. GSC never prices; a quote comes from the retailer's program.
• find_buyer
  Qualify the buyer: find a maker on the grocery record by name, with its own website where the record has one.
• submit_demand
  Hand off: the packet — the maker, a budget a person has approved, one or more GTINs, a market and a list of banners — or a gap naming what is missing. Routes each banner by its card status: unclaimed is a referral, claimed goes to the retailer's media team, registered goes agent to agent. Settles at
• receive_demand
  Retailer side: a registered program agent takes a qualified packet. Only a card in the registered state can receive; any other card is refused and nothing is charged.
• a2a_handoff
  Hand to a person: the state of a handoff and its Navigator desk ticket, where the media program has no agent.
• pull_measurement
  Read the till: results of a campaign, returned by the retailer's program. Available only after the program returns a campaign id for a handoff.
• renew_package
  Renew: a prior quote id from the retailer's program and a new approved budget. Without a quote id from the program there is nothing to renew.
• log_audit
  Write one audit line for a step of the chain; returns its id.
• enrol_maker
  Makers: be seen. Enrol a maker for media exposure in grocery: its name, its markets (one or more of the 20), the tick, and a contact a person can answer. Enrolment only — a handoff waits for a budget a person has approved.
