❓ Frequently Asked Questions
Why do API docs use cURL examples? ▾
cURL is universal — it works on every OS and shows the raw HTTP request clearly. Developers then convert it to their preferred language. This tool automates that conversion for JavaScript.
What is the difference between fetch and axios? ▾
fetch is built into modern browsers and Node.js 18+. axios is a third-party library with additional features like interceptors, automatic JSON parsing and better error handling. Both are widely used.
Does this handle authentication headers? ▾
Yes — Authorization: Bearer token and other headers are converted correctly. API keys in -H headers are preserved in the output code.
