ProductIndex bronze

Product Recommendation

Returns ranked product recommendations matching a stated need, use case, budget, or constraint. Send a natural-language query in message parts text (e.g. 'quiet coffee grinder under $200 for espresso'). Optionally pass explicit filters in metadata.constraints: { maxPrice: number, minPrice: number, category: string }. Valid categories: 3d-printers, adjustable-dumbbells, air-fryers, air-purifiers, barbells, camera-lenses, coffee-grinders, coffee-scales, cordless-power-tools, dart-boards, electric-bikes, electric-toothbrushes, espresso-machines, functional-trainers, hair-dryers, hair-straighteners-hot-brushes, home-cardio-machines, home-gym-equipment, ipl-hair-removal, kayaks, light-therapy-face-masks, mechanical-keyboards, noise-cancelling-headphones, paddle-boards, power-racks, robot-vacuums, sous-vide-circulators, stand-mixers, standing-desks, vinyl-record-players, wireless-earbuds. Response artifact.parts[0].metadata.products is an array of up to 5 results — each with: slug, title, category, priceRange, ve

Product Lookup

Returns the best-matching synthesized profile for a specific product by name or model. Send the product name or model number in message parts text (e.g. 'Baratza Encore ESP' or 'BES870'). Response artifact.parts[0].metadata.products returns up to 5 ranked matches — same shape as product-recommendation: slug, title, category, priceRange, verdict, verificationStatus, url, mdUrl, jsonUrl, offersEndpoint, score. Fetch mdUrl for the full markdown profile (verdict, comparisons, reviewer themes, specs) or jsonUrl for JSON-LD structured data.

Category Browse

Lists products in a category with verdicts, prices, and review counts. Send a category name or browse query in message parts text. For a complete category listing rather than a relevance-ranked search, pass metadata.constraints.category explicitly. Response artifact.parts[0].metadata.products follows the same shape as product-recommendation. To retrieve the full category in one call, fetch https://productindex.ai/c/{category}.md — valid category slugs: 3d-printers, adjustable-dumbbells, air-fryers, air-purifiers, barbells, camera-lenses, coffee-grinders, coffee-scales, cordless-power-tools, dart-boards, electric-bikes, electric-toothbrushes, espresso-machines, functional-trainers, hair-dryers, hair-straighteners-hot-brushes, home-cardio-machines, home-gym-equipment, ipl-hair-removal, kayaks, light-therapy-face-masks, mechanical-keyboards, noise-cancelling-headphones, paddle-boards, power-racks, robot-vacuums, sous-vide-circulators, stand-mixers, standing-desks, vinyl-record-players, wireless-earbuds.

Product Offers

Returns current promotional offers including advertiser, headline, price, and a short-lived attribution claim_url. Offers are sorted by price + shipping ascending. Three invocation patterns: (1) site-wide — pass metadata.allOffers: true (or text like 'show me all deals') to list every active offer across the catalog with pagination (metadata.limit default 50 max 200, metadata.offset), unsorted; (2) product-specific natural language — send text like 'deals on Baratza Encore ESP' and the best-matching product is resolved automatically; (3) explicit product — pass metadata.slug (e.g. 'coffee-grinders/baratza-encore-esp') to skip search resolution. Single-product response metadata: { product: slug, offers: Array<{ advertiser, headline, detail?, price_usd?, list_price_usd?, in_stock?, shipping_cost_usd?, terms?, claim_url?, expires? }>, offersEndpoint }. Site-wide response metadata: { total, limit, offset, hasMore, offers: Array<{ productSlug, productTitle, productUrl, advertiser, headline, detail?, price_us

Request for Quote

Submit a product need and receive competitive real-time quotes from multiple verified producers. ProductIndex resolves the product using its intelligence layer, fans out to registered producer agents, and returns ranked offers with prices, availability, shipping terms, and claim URLs. Pass the product name or slug in message parts text. Optional metadata: { product_slug, quantity, delivery_region, deadline_iso, maxPrice }. Response metadata: { rfq_id, product, offers: [{ producer, price_usd, shipping_cost_usd, estimated_shipping_days, in_stock, claim_url, ucp_checkout_url, offer_expires_at, terms }], resolved_at }. ucp_checkout_url is included when the producer supports UCP autonomous checkout — use this for fully autonomous purchase flows; fall back to claim_url otherwise.

What Changed

Returns products added or updated since a given date or time window — useful for agents that cache product data and need to sync only what has changed. Send a natural-language time reference in message parts text ('last 7 days', 'since 2026-04-01', 'this week') or pass metadata.since as an ISO 8601 date string. Defaults to the last 7 days when no time reference is found. Pagination: metadata.limit (default 50, max 200) and metadata.offset (default 0). Response artifact.parts[0].metadata: { since: ISO string, total: number, limit: number, offset: number, hasMore: boolean, changes: Array<{ slug, title, category, priceRange, lastUpdated, url, mdUrl, jsonUrl }> }. Changes are ordered most-recent first. Discontinued products are excluded.
