What is API Request Builder?
API Request Builder lets you assemble an HTTP method, URL, query string, headers and body, then copy the request as cURL or send it with this browser's fetch. Fah Swe never proxies the call — your browser talks to the destination, so cross-origin APIs may be blocked by CORS. Tokens stay in the page unless you send the request; they are not persisted by default and are never sent to analytics. This is not a hosted API gateway, Postman cloud workspace or secret vault.
Key features
- Method, URL, query, headers and body on one form
- Copy as cURL for a terminal or another client
- Optional send via this browser's fetch — status, timing and response
- No Fah Swe HTTP proxy and no server-side request log
- Tokens not stored by default; not sent to analytics
Popular uses
- Draft a request and hand a cURL line to a teammate
- Probe an API that already allows this origin (CORS)
- Inspect status and body without pasting a token into a third-party cloud client
Supported formats
No file upload. Optional send is a same-tab browser fetch. Copy cURL as text.
Troubleshooting
- Send fails with a CORS error The destination usually must allow this origin. Use Copy as cURL in a terminal if the API is not browser-callable.
Also known as: Browser HTTP client, cURL generator, REST request builder.
How it works
- Enter method, URL, optional query, headers and body.
- Copy as cURL, or send from this browser to inspect status, timing and response.
- Tokens stay in the page unless you send the request to the destination server.
FAQ
Does Fah Swe proxy the request?
No. There is no server-side HTTP proxy. Send uses your browser’s fetch; CORS may block cross-origin APIs.
Are tokens stored?
No. Nothing is persisted by default and tokens are never sent to analytics.
Where do Authorization headers go?
They stay in this tab until you send. The destination server then receives them from your browser, not from Fah Swe.
