Getting Started

To use Corsfix, add https://proxy.corsfix.com/? before your URL when making fetch requests.

// Add Corsfix URL before the API
// https://proxy.corsfix.com/? + https://api.example.com/data

fetch("https://proxy.corsfix.com/?https://api.example.com/data");

Basic Usage

// GET request
fetch("https://proxy.corsfix.com/?https://api.example.com/users")
  .then((response) => response.json())
  .then((data) => console.log(data));

// POST request
fetch("https://proxy.corsfix.com/?https://api.example.com/users", {
  method: "POST",
  body: JSON.stringify({ name: "John" }),
  headers: {
    "Content-Type": "application/json",
  },
});

API Key

You should use the domain whitelist via the dashboard. If that’s not possible for your use case, you can fall back to using an API key.

fetch("https://proxy.corsfix.com/?https://api.example.com/data", {
  headers: {
    "x-corsfix-key": "cfx_12345678",
  },
});

We discourage using API key on the client side, as it can be exposed in your source code and browser network requests.
