Server instructions

A2A Retailmedia — the agentic retail-media hub for grocery, operated by GreenCore Solutions Corp. The retailer is the seller of media; the maker's agent is the buyer. Every grocery banner in 20 markets has a signed card with a status: unclaimed, claimed or registered. Reads are open. For a handshake call resolve_jurisdiction, then resolve_actor, then gate_transaction, then find_makers, resolve_gtin, check_eligibility, list_banners, list_packages, quote_package, find_buyer and submit_demand. submit_demand needs four things — the maker, a budget a person has approved, a Global Trade Item Number (GTIN) and a list of banners — or it returns a gap. GSC owns no inventory, runs no auction, makes no creative and quotes no price. Artificial intelligence makes mistakes. A2A Retailmedia is an agentic information source, not a recommendation. No ads, ever. No rank for sale. Trade only.

Known tools 19

resolve_jurisdiction

Where is the media bought?

Inferred read-only

resolve_actor

Who is asking?

Inferred read-only

gate_transaction

The gate before a handshake: allow or deny for one market and one actor class.

Inferred read-only

find_makers

Find the brand: makers on the grocery record of one market (node = one of the 20 markets).

Inferred read-only

resolve_gtin

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.

Potential side effects

check_eligibility

Confirm it is on the shelf: does the grocery record list this GTIN at this banner in this market?

Inferred read-only

list_banners

Pick the banners: the grocery banners of one market with each one's media program (or "none listed") and card status.

Inferred read-only

get_banner_card

The signed card of one banner and its status (unclaimed, claimed or registered).

Inferred read-only

list_banner_cards

The cards of one market, optionally by status (unclaimed, claimed, registered): banner, media program, status and the card's address.

Inferred read-only

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.

Inferred read-only

quote_package

Price it: returns where the banner's own media program publishes its rates or takes an enquiry.

Inferred read-only

find_buyer

Qualify the buyer: find a maker on the grocery record by name, with its own website where the record has one.

Inferred read-only

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.

Inferred read-only

receive_demand

Retailer side: a registered program agent takes a qualified packet.

Inferred read-only

a2a_handoff

Hand to a person: the state of a handoff and its Navigator desk ticket, where the media program has no agent.

Inferred read-only

pull_measurement

Read the till: results of a campaign, returned by the retailer's program.

Inferred read-only

renew_package

Renew: a prior quote id from the retailer's program and a new approved budget.

Inferred read-only

log_audit

Write one audit line for a step of the chain; returns its id.

Potential side effects

enrol_maker

Makers: be seen.

Inferred read-only
