Capabilities

Tools 19

a2a_handoff

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

Discovered
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.

Discovered
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.

Discovered
find_buyer

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

Discovered
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.

Discovered
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.

Discovered
get_banner_card

The signed card of one banner and its status (listed · claimed · verified). banner = the banner's slug, id or name.

Discovered
list_banner_cards

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

Discovered
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.

Discovered
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.

Discovered
log_audit

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

Discovered
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.

Discovered
quote_package

Price it: returns where the banner's own media program publishes its rates or takes an enquiry. wefetch never prices; a quote comes from the retailer's program.

Discovered
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.

Discovered
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.

Discovered
resolve_actor

Who is asking? maker, brand_owner, agency, distributor or retailer_media_team (trade); auditor (read only). The consumer is never the counterparty.

Discovered
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.

Discovered
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.

Discovered
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.
