Baselayer Documentation Structure
Every Baselayer product follows the same core structure in this documentation. At a minimum, each product’s documentation includes these pages:
- Basics: what the product does, key concepts, terminology, and when to use it.
- API Quickstart: the fastest path to a successful first request (auth + a simple example).
- Best Practices: guidance on real-world usage - recommended workflows, edge cases, rate limits, and common pitfalls.
Some products may include additional pages when needed to explain product-specific behavior or advanced concepts. For example, Business Search includes a dedicated page for Scores & Ratings to clarify how scoring works and how to interpret results.
