• search_products read-only

  Search the 25karats made-to-order catalog (wedding bands, engagement rings, his & hers sets, fine jewelry) by keywords or a style code. Use this first when a shopper describes what they want ("braided mens wedding band", "vintage engagement ring"). Returns product cards with live starting prices in USD, image URLs, and product URLs. Follow up with get_product for options and price_product for an exact configured price. total_count is exact unless capped is true; capped counts are lower bounds imposed by the search index.

  Parameters:

  • query (required) — string — Keywords or a style code (e.g. 'HC100232')
  • page — integer — Requested page; values below 1 are clamped and reported
  • tags — array — Every supplied style tag must match, by slug, name, or id
  • limit — integer — Requested results per page (default 10); values outside 1..24 are clamped and reported
  • metal — string — Optional metal filter; each returned starting price and URL use this metal's variant
  • category — string — Optional shopper-facing catalog category. engagement_rings / wedding_bands / his_hers_sets / jewelry select a product line; mens_rings and womens_diamond_rings select the site's men's (/wedding-rings/mens) and women's (/wedding-rings/womens) ring collections, which hold plain bands and diamond rings alike
  • price_max — number
  • price_min — number
  • product_line — string — Optional product-line filter; category is preferred

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• browse_collection read-only

  Browse one collection/category page deterministically — the same product set, ordering, and filters a shopper sees on the site. Pass the collection permalink from list_collections (e.g. 'wedding-rings/womens/eternity'). Filter by style tags, metals, or sort; paginate 24 per page. Prefer search_products for free-text intent and this tool for "show me everything in X".

  Parameters:

  • collection (required) — string — Collection permalink, with or without leading slash
  • cats — array — Child-category slugs on a listing-nav collection; matches the site's cats filter
  • page — integer
  • sort — string — Default: best sellers
  • tags — array — Style tag slugs, e.g. ['celtic','braided']
  • limit — integer — Max 24
  • metals — ['string', 'array'] — Offered metal codes, e.g. ['14K','PLAT']; price and URL use the first offered selection
  • price_tag — ['string', 'integer', 'array'] — Price-range slug or id, e.g. '501-1000'; accepts one value or an array

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_collections read-only

  The navigable catalog taxonomy: every public collection with its permalink (for browse_collection), title, and product count, as a tree. Call once to orient; results change rarely.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_product read-only

  Full detail for one product: metal variants with live starting prices, the complete customization matrix (ring sizes, widths, thickness, color, finish, stone type, engraving rules) with the ids to echo into price_product, stone specifications, physical dimensions, size-group siblings, matching pieces, and the default image. Identify the product by exactly one of slug, style_code, or url (any 25karats product URL works).

  Parameters:

  • url — string — Any 25karats.com product URL
  • slug — string — Product page slug, e.g. 'floral-antique-handmade-wedding-ring'
  • metal — string — Optionally preselect a metal variant
  • style_code — string — Style/SKU code shown on the product page, e.g. 'HC100232'

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• price_product read-only

  Exact live price in USD for a fully configured item — the same number the customer pays on 25karats.com (computed from current metal market pricing, not a cached feed price). Identify the item by variant_id (from get_product) or style_code, optionally with metal. For wedding bands pass ring_size/width/thickness/color/finish (option_value ids or display values from get_product); for his & hers sets pass his/her objects with those keys; for engagement rings pass stone_type and ring_size. Unset axes use the product's defaults. Returns the price, the resolved configuration, and a deep_link_url that opens the product page pre-configured for checkout. Invalid values return the list of valid ones — correct and retry. Any option group can also be set through the options object keyed by the option_id values returned by get_product (the only way to configure generic jewelry). His & hers options and engraving belong inside the respective his/her object. Inputs that do not apply to the item (stone_type on a band, top-level ring_size on a set) are rejected with the inputs that do; settings sold without a center stone say so in configuration and notes.

  Parameters:

  • her — object — His & hers sets: configuration and optional engraving for the her band
  • his — object — His & hers sets: configuration and optional engraving for the his band
  • url — string
  • slug — string
  • color — string
  • metal — string
  • width — string — Bands: option_value id or display value, e.g. '6' (mm)
  • finish — string
  • options — object — Map option_id (from get_product) to an option_value id or display label; an alternative to the named axes for any customizable item
  • ring_size — string
  • thickness — string
  • stone_type — string — Engagement rings with a diamond-type choice: 'natural' or 'lab' (or the id from get_product). Rejected on settings sold without a center stone (get_product shows stone_types: [] and setting_only: true)
  • style_code — string
  • variant_id — integer — Variant id from get_product (preferred)
  • engraving_font — string — Wedding bands only; for H&H put this inside his/her
  • engraving_text — string — Wedding bands only; for H&H put this inside his/her

• get_product_images read-only

  Every gallery image for a product with high-resolution URLs. Each image lists only renditions that actually exist, largest first — modern photography is 2048x2048 WebP at the 'original' size — plus the metal tone, band width, and finish the photo shows, and descriptive alt text. Identify the product by exactly one of slug, style_code, or url.

  Parameters:

  • url — string
  • slug — string
  • metal_tone — string — Optionally return only photos showing this metal tone
  • style_code — string
