Mirror API
A utility endpoint that echoes submitted payloads to help developers
debug structure, formatting, and delivery without risk.
About This Project
Mirror API acts as a passive receiver that returns whatever data you
send to it. This makes it useful for developers testing frontend
submission formats, integration flows or webhook payloads.
Think of it like a test mirror for your client logic: It helps you
catch errors early before calling real APIs.
How It Was Built
This tool uses a front-end form built with HTML and JavaScript to
POST a payload to a mock endpoint. Responses are parsed and shown
instantly on the page. Styled for clarity and structured around
test/debug scenarios.
The logic focuses on JSON formatting, POST method handling and
dynamic UI rendering of response data.

FAQ
Q: Does this store my data?
A: No. It only reflects your input back to the
screen. Nothing is saved.
Q: Can I test a real API here?
A: No. It’s only for local or mock POST testing.
For live APIs, use tools like Postman or Insomnia.
