How It Works

1. Get Your API Key

Sign up at buywhere.ai/api and get an API key instantly. Free tier includes 100 requests/minute — no credit card required.

2. Query the Catalog

Use the REST API, GraphQL endpoint, or MCP server. Search by keyword, filter by price/brand/source, compare across platforms, or find the best deal.

Example — Search for a product:

curl -H "Authorization: Bearer $BUYWHERE_API_KEY" \
  "https://api.buywhere.ai/api/v1/products?q=iphone+15+pro&limit=5"

Example — Find the best price:

curl -H "Authorization: Bearer $BUYWHERE_API_KEY" \
  "https://api.buywhere.ai/api/v1/products/best-price?q=iphone+15+pro"

Example — Compare across platforms:

curl -H "Authorization: Bearer $BUYWHERE_API_KEY" \
  -X POST "https://api.buywhere.ai/api/v1/products/compare" \
  -d '{"product_ids": [12345, 67890]}'

3. Build Your Product

Use the data to power price-comparison widgets, deal alerts, purchase recommendations, or AI agent shopping assistants. Webhooks fire on price drops so your users never miss a deal.

Use Cases

AI Shopping Assistants

Give your AI agent real product data. Instead of hallucinating prices, it queries BuyWhere and returns actual listings with affiliate links. Supports MCP integration with Claude, Cursor, and any MCP-compatible client.

Price Comparison Tools

Aggregate real-time prices across Singapore's biggest retailers. Show users exactly where to buy for the lowest price — with direct purchase links and affiliate attribution.

Deal Alerts & Price Tracking

Track price changes on any product. Webhooks notify your system when prices drop below a threshold, so you can alert users at exactly the right moment.

E-Commerce Data Pipelines

Bulk export millions of products in CSV or JSON for your data warehouse. Structured, normalized, and updated daily — ready for analytics, ML training, or competitive intelligence.

Affiliate Commerce

Access affiliate-linked product URLs for Shopee, Lazada, Amazon, and major regional retailers. Earn commissions on every redirected sale — no scraping required.
