What the cURL Command Generator does
cURL Command Generator: generates Status, curl command and Single line from URL, Method and Headers (one per line, Name: value). Example: URL https://api.example.com/v1/users?page=1, method GET and headers (one per line, name: value) Accept: application/json gives status GET request with 1 header(s).
Status, curl command and Single line, derived from URL, Method, Headers (one per line, Name: value) and Body (JSON or form data). Each change is reflected immediately, which suits quick what-if comparisons.
Spotting a malformed field is far quicker when the structure is laid out clearly. The cURL Command Generator exists to take that particular chore off your hands.
The page holds your values in memory and forgets them the moment you close it.
If you want to check the arithmetic, the field table, the method and a worked example are further down.
What do the cURL Command Generator fields mean?
The cURL Command Generator uses 9 inputs. Every box starts with a working value, so there is a real result on screen before you touch anything.
| Field | What to enter | Default |
|---|---|---|
| URL | required | https://api.example.com/v1/users?page=1 |
| Method | choose from GET, POST, PUT, PATCH, DELETE or HEAD | GET |
| Headers (one per line, Name: value) | paste or type any amount of text | Accept: application/json |
| Body (JSON or form data) | paste or type any amount of text | none |
| Basic auth (user:password) | optional | none |
| Bearer token | optional | none |
| Follow redirects (-L) | choose from No or Yes | No |
| Show response headers (-i) | choose from No or Yes | No |
| Skip TLS verification (-k) | choose from No or Yes | No |
How does the cURL Command Generator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same generated output.
Range checks come first, so the formula only ever sees values it can handle.
Worked example
These are the values the cURL Command Generator loads by default, and the result it produces from them. The figures are the tool’s live defaults and its live output, so you can reproduce them exactly.
| URL | https://api.example.com/v1/users?page=1 |
|---|---|
| Method | GET |
| Headers (one per line, Name: value) | Accept: application/json |
| Body (JSON or form data) | (empty) |
| Basic auth (user:password) | (empty) |
| Bearer token | (empty) |
| Follow redirects (-L) | No |
| Show response headers (-i) | No |
| Skip TLS verification (-k) | No |
| Status | GET request with 1 header(s) |
|---|---|
| curl command | curl \ -H 'Accept: application/json' \ 'https://api.example.com/v1/users?page=1' |
| Single line | curl -H 'Accept: application/json' 'https://api.example.com/v1/users?page=1' |
How to use it
- Fill in URL.
- Pick a value for Method: the options are GET, POST, PUT, PATCH, DELETE or HEAD.
- Paste your content into Headers (one per line, Name: value).
- Paste your content into Body (JSON or form data).
- Put Basic auth (user:password).
- Key in Bearer token.
- Pick a value for Follow redirects (-L): the options are No or Yes.
- Pick a value for Show response headers (-i): the options are No or Yes.
- Pick a value for Skip TLS verification (-k): the options are No or Yes.
- Type a value and the answer is already there by the time you stop.
- The panel reports Status, curl command and Single line.
- The link encodes your inputs, so saving it is enough to reproduce the result later.
What this tool does not do
- Output follows the common convention for this format; a specific toolchain may have its own house style.
- Processing happens in your browser, so very large inputs are bounded by available memory.
- It assumes the values you give are already consistent with each other.
Frequently asked questions
The form asks for URL, Method, Headers (one per line, Name: value), Body (JSON or form data), Basic auth (user:password), Bearer token, Follow redirects (-L), Show response headers (-i) and Skip TLS verification (-k). Defaults are loaded for all of them, letting you treat it as a what-if tool rather than a data-entry form.
With the values loaded when the page opens, status comes out as GET request with 1 header(s). That number tracks the inputs, so a small edit shows its sensitivity immediately.
Nothing is stored. The page has no back end to send data to, and holds your input only in memory.
Free, and there is no upsell. The whole tool is the free version.
Full double precision is used throughout; only the displayed figure is shortened.
