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. params: market* |
resolve_actor | Who is asking? maker, brand_owner, agency, distributor or retailer_media_team (trade); auditor (read only). The consumer is never the counterparty. params: actor_class* |
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. params: market*, actor_class* |
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. params: segment, region, node, limit |
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. params: gtin* |
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. params: gtin*, banner*, country_iso* |
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. params: market*, with_program, search, limit, offset |
get_banner_card | The signed card of one banner and its status (listed · claimed · verified). banner = the banner's slug, id or name. params: market*, banner* |
list_banner_cards | The cards of one market, optionally by status (unclaimed, claimed, registered): banner, media program, status and the card's address. params: market*, status, limit, offset |
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. params: market*, banner*, decision_id |
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. params: market*, banner*, decision_id |
find_buyer | Qualify the buyer: find a maker on the grocery record by name, with its own website where the record has one. params: maker*, market, decision_id |
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 the door. params: maker*, budget*, budget_approved_by*, gtins*, market*, banners*, contact*, decision_id, note |
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. params: market*, banner*, handoff_id*, decision_id |
a2a_handoff | Hand to a person: the state of a handoff and its Navigator desk ticket, where the media program has no agent. params: handoff_id* |
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. params: handoff_id* |
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. params: prior_quote_id*, budget*, budget_approved_by*, decision_id |
log_audit | Write one audit line for a step of the chain; returns its id. params: event*, detail |
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. params: maker*, markets*, media_exposure*, contact* |
