Comparison of usage
How to use Serpex?
To use Serpex, developers can integrate its REST API or SDKs (available for JavaScript, Python, cURL) into their applications. Users make API calls by specifying parameters such as the query (q), desired search engine (or 'auto' for routing), category, and time range. Serpex then processes the query, handles any blocking or CAPTCHAs, and returns structured JSON search results. An interactive playground is available for testing queries and managing API keys.
How to use Flatkey AI?
To use flatkey.ai, create an account on their platform and generate a single API key from the dashboard. Next, configure your local environment or AI tools (like Codex CLI or Claude Code) by running their one-line installation command or pointing your OpenAI-compatible client to the base URL (https://router.flatkey.ai/v1). Finally, monitor your multi-model usage, costs, and errors directly through the unified dashboard.
