Building with a product search API: a developer's guide
Whether you're building a shopping assistant, comparison tool, or recommendation engine, you need a way to search products in real time. This guide walks through what to look for in a product search API and how to get started.
Why use a product search API?
Scraping or aggregating product data yourself is brittle and expensive. Individual brand APIs and affiliate feeds are fragmented — you'd need to integrate hundreds of sources to cover meaningful inventory. A unified product search API gives you one integration, one query, and results that span millions of products across thousands of brands.
What to look for
- Real-time data — Prices and availability that reflect current catalogs, not stale snapshots.
- Semantic search — Natural-language queries like "durable backpack for commuting" that understand intent.
- Rich results — Images, descriptions, variants, and links so you can build a full experience.
- Monetization — Affiliate-ready links so you can earn commission when users buy.
Getting started
Channel3's API supports text search, filters (brand, price, category), and optional image-based search. You can use our TypeScript or Python SDK or call the REST API directly. Sign up for an API key and start querying in minutes.
