## Tools (as reported by the server, not verified)

- `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.
