global_search | Use this when a user wants to find or compare product candidates across participating WooCommerce merchants. Search cards include bounded variants_compact and variant_option_values from the merchant snapshot. Option values are independent and do not prove a purchasable combination. Verify the selected variant, price and stock through its merchant Bridge handoff before confirming an offer. For a re params: q, leaf, brand, gender, color, in_stock, min_price, max_price, price_currency, limit, variant, variant_facets, variant_facets_limit, variant_in_stock, variant_price_min, variant_price_max, variant_price_currency, variant_limit, merchant, result_facets, cursor |
get_offer_attestation | Returns a cryptographic proof that this offer's product row is exactly the one the merchant signed in its catalog snapshot: the signed row, its bucket hashes, the Ed25519-signed manifest, the merchant public key and step-by-step verification. Trust is anchored on the merchant domain (key fingerprint published at key_anchor), not on KaliCart. It proves the row as signed at snapshot.generated_at, no params: p2209_id* |
estimate_delivered_cost | Deterministic estimate from the merchant's own data: item price x quantity plus the shipping options the store declares for the destination (flat rate = declared base rate; free shipping with its threshold, whether this quantity reaches it and how much is missing). Lists what is not included (shipping classes, cost formulas, duties, taxes on shipping). Pass variation_id for variable products. Vali params: p2209_id*, variation_id, quantity, destination*, max_age_seconds, live |
verify_basket | For a multi-item request, collect p2209_id and any selected variation_id from global_search results and send all selected items in one call. For every variable product, include a variation_id from its selected variants_compact entry on the first call; without it the price and basket total may be unknown. Never substitute WooCommerce numeric product IDs for p2209_id. Set live=false for a snapshot-o params: items*, destination, destination_details, quote, max_age_seconds, live |
verify_offer | Checks ONE offer (optionally a selected variant) and returns true, false or unknown per constraint with evidence. Pass constraints as an ARRAY, for example [{"field":"available"},{"field":"price","max":300,"currency":"EUR"},{"field":"ships_to","value":"IT:CB"}]. available has no expected key: ask for the fact and read its result. For a merchant-declared variant option use {"field":"option","keys": params: p2209_id*, variation_id, constraints*, max_age_seconds, live |
lookup_merchant | Use this when the user already knows a merchant domain and needs to check whether it publishes a KaliCart Bridge catalog, its latest observed access state, or its federation consent. This tool only reads the Global registry and never probes or modifies the merchant. Do not use it to discover products; use global_search instead. params: domain* |
get_product | Use this after global_search when the selected candidate needs indexed details that are not already on its search card. The p2209_id must come from global_search. Variant options and colors are merchant-declared snapshot evidence matched by variation ID. This remains a snapshot, not live merchant verification; follow the returned handoff before confirming variant, price, or stock. Skip this call w params: p2209_id* |
list_merchants | Use this to inspect which WooCommerce merchants currently participate in the searchable KaliCart Global catalog and how much catalog coverage each contributes. It returns stable merchant identifiers, domains, storefront URLs, product counts, and sync time. Do not use it to find products; use global_search instead. params: limit |
list_categories | Use this to discover the canonical category paths currently represented in KaliCart Global before calling global_search with leaf. An optional parent returns that node and its full subtree. This lists category vocabulary and counts; it does not return products. params: parent |
