- Search & Filtering – Enable keyword-based and advanced filtering (e.g., pricing, protocol)
- Documentation Access – Provide endpoints, parameters, and usage guides
- Testing Tools – Allow real-time API calls directly within the platform
(Quick Facts):
- API search engines aggregate thousands of APIs
- They support REST, GraphQL, and other protocols
- Many include built-in testing environments
- Results are ranked based on relevance, popularity, and performance
