curl to code

Paste the curl command from any API documentation and get the same request in the language you are actually writing.

import requests

headers = {
    'Authorization': 'Bearer $VIRLO_API_KEY',
}

params = {
    'start_date': '2026-09-01',
    'end_date': '2026-09-30',
    'order_by': 'views',
    'limit': '10',
}

response = requests.get('https://api.virlo.ai/v1/hashtags', headers=headers, params=params)
response.raise_for_status()
print(response.json())

Why this exists

Every API documents its endpoints in curl, and almost nobody ships curl. The translation is mechanical but fiddly: headers become a dict or a map, -d becomes a body or a query string depending on whether -G is present, and basic auth becomes a different construct in each language. Getting one of those wrong produces a 400 that looks like an API problem and is not.

What to check in the output

  • The method. curl infers POST from the presence of a body. If the original had no explicit -X, confirm the inferred method is the one the endpoint expects.
  • The body encoding. A JSON body needs a JSON content-type header. The converter passes your body through verbatim rather than guessing, so if the header was missing from the curl command it will be missing from the code.
  • The secret. The generated snippet contains whatever the command contained. Move the key to an environment variable before it reaches a commit.

After the first call

A converted snippet gets one request working. Production needs the parts curl never shows: retries with backoff on a 429, a timeout shorter than your own request budget, and pagination through the cursor. Those are documented per endpoint, and the rate-limit calculator below works out the pace your job needs before you write the loop.

FAQ

Which curl flags are supported?
The ones that appear in API documentation: -X / --request, -H / --header, -d and its --data variants, -G, -u / --user, -A, -b, -e, -L and -k. Line continuations with a trailing backslash are handled. Anything unrecognised is reported rather than silently dropped.
Is my API key sent anywhere?
No. The parser and the code generators are plain functions running in this page, so a command with a live bearer token in it never leaves your browser. There is no signup and no request to our servers.
Why does -G change the output?
Without -G, curl sends -d values as a request body and makes the request a POST. With -G it appends them to the query string and keeps the method as GET. The generated code follows the same rule, which is why the same -d flags can end up as params or as a body.
Does it handle multipart uploads?
Not properly. -F is flagged with a warning and the value is passed through as a body, because a faithful multipart conversion differs enough per language that a half-right version would cost more time than it saves.
Which languages does it output?
Python with requests, JavaScript with fetch, Node with axios, Go with net/http, and PHP with the curl extension. Each one is idiomatic rather than minimal: the Python version raises on a bad status, and the Go version closes the body.
Can I convert a Virlo API call with it?
Yes — the example loaded on the page is a real hashtag call. Every curl snippet in the Virlo docs converts the same way, so the quickest route to a working client is to copy a documented call and switch the language here.
