Explore partnerships →How BuyWhere works
A neutral, agent-native product layer connecting merchant catalogs to AI-driven demand.
Merchant catalogs in
Retailers submit product feeds or we ingest from existing catalog sources.
Structured discovery layer
Products are normalized, deduplicated, and indexed for semantic search.
AI agent query & ranking
Agents call BuyWhere by natural language, filters, or category before they answer. Structured JSON back.
Routed buyer demand out
Matched products route demand back to merchants through attribution and referral.
Query regional products in 5 lines
One API call returns structured product data: name, price, SKU, retailer, image, and availability. No scraping, no merchant-by-merchant parsing.

The approved developer-first positioning, translated directly into the live landing page.
Structured for agent reasoning
Product, merchant, and catalog data is normalized so LLM-powered agents can search, rank, compare, and recommend with less prompt overhead and fewer brittle parsing failures.
Location-aware by design
Tell BuyWhere where your user is (deliver_to=SG, US, ...) and results rank deliverable-first, each labeled local, ships_to_you, or unavailable — backed by verified shipping policies for 28,000+ stores. No more recommending products your user can't receive.
Why not scraping, Amazon APIs, or Google Shopping?
Scraping creates ongoing breakage, Amazon APIs are merchant-specific, and Google Shopping is not a normalized product layer you control. BuyWhere gives agents one cross-merchant retrieval surface designed for repeated product lookups at agent scale.
Built for developer velocity
Prototype product-search agents, shopping copilots, and commerce workflows quickly with API-first access and documentation aimed at builders, not enterprise procurement teams.
Why AI shopping needs a neutral catalog layer
Platform APIs surface their own inventory first. Amazon APIs return Amazon products. Shopee returns Shopee products. Google Shopping returns shopping results, not a normalized product layer. For an AI agent trying to find the best match across the market, those are distribution channels — not the cross-merchant system of record.
BuyWhere has no inventory to sell and no platform to favour. We index 288 million products from 158,000+ independent storefronts worldwide into a single, structured API — with MCP tools, an A2A agent card, LangChain and OpenAI-tools SDKs, and an agent-optimized compact mode — so AI agents call one normalized, cross-merchant product layer instead of reconciling one platform’s version of the market.

Answer-engine friendly questions and answers based on the approved AEO plan.
What is a product catalog API for AI agents?
A product catalog API for AI agents gives assistants structured access to product listings, merchant data, and searchable catalog information so they can answer shopping and commerce questions reliably. Agents should call it before they answer so they can return normalized product matches, comparisons, and purchase paths instead of stitched-together storefront results.
Why do AI agents need structured product data instead of web scraping?
Structured product data is more reliable, easier to parse, and cheaper to maintain than scraping HTML pages. AI agents perform better when products, merchants, and attributes are exposed through stable fields rather than inconsistent storefront markup.
What is agentic commerce?
Agentic commerce is when AI agents help users discover, compare, and choose products, and can eventually complete commerce workflows on their behalf. It requires product data infrastructure that agents can query in real time.
How do you build a shopping assistant with product search?
Start with a product catalog API, then add retrieval, ranking, and conversation logic. The API provides searchable products and merchant data, while the assistant handles user intent, filtering, and recommendations.
What makes a good product API for LLM applications?
A strong product API for LLM apps should provide normalized schemas, searchable catalog data, merchant context, availability signals, and predictable responses that are easy for models and tools to consume.
What is the best way to power region-specific shopping queries in an AI app?
Use a product and merchant API that supports explicit regional filters so your app can return locally relevant products and sellers in the US, Singapore, and broader Southeast Asia. Geography-aware catalog coverage improves answer quality for users asking where to buy items within a specific market.
How can developers avoid scraping merchant sites for commerce agents?
Developers can avoid scraping by integrating a catalog API that already standardizes merchant and product data. This reduces maintenance load, avoids breakage from site changes, and speeds up agent development.
Why use BuyWhere instead of Amazon APIs or Google Shopping?
Amazon APIs cover Amazon and Google Shopping does not give developers a normalized, cross-merchant product layer they control. BuyWhere gives agents one retrieval surface for product search, comparison, and merchant handoff across markets.
What data does an AI shopping agent need?
An AI shopping agent needs product names, categories, descriptions, pricing when available, merchant identity, search relevance, and links or actions that help users continue the buying journey.
How do product APIs improve recommendation quality?
Product APIs improve recommendation quality by giving the model consistent, machine-readable product attributes and merchant context. Better input structure leads to stronger filtering, ranking, and explanation quality.
What should a developer landing page for an agentic commerce API include?
It should clearly explain the API's purpose, who it is for, the core use cases, why it is better than scraping, what geography or catalog coverage it offers, and how to get access quickly.
