Overview

CORS Proxy acts as a middle-man server that forwards your HTTP requests to external APIs, stripping restrictive CORS headers so browsers can access them without cross-origin errors. It is useful during local development when you need to call third-party APIs that do not include permissive CORS headers. No authentication or API key is required.

Beginner Tip

Browsers block requests to external APIs from different origins by default. This proxy forwards your request server-side, bypassing that restriction. Use it for development and testing only — in production you should configure CORS on your own server.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

JSON Response · Illustrative
{
  "status": "success",
  "data": {
    "result": "Data from CORS Proxy",
    "description": "Get around the dreaded CORS error by using this proxy as a middle man",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

status Success or failure indicator for the proxy request itself.
data.result The proxied response body from the target API.
data.description Human-readable description of the proxy operation.
data.timestamp ISO 8601 timestamp of when the proxied request was processed.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://api.allorigins.win/get?url=https://httpbin.org/get";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

403 Forbidden from target API The target API blocks requests from proxy IP ranges or requires special headers
Try sending the request directly or add required headers like Authorization or Referer to your proxy request.
Proxy returns target error unchanged CORS Proxy transparently forwards non-2xx responses from the target server
Check the target URL is correct and the API itself is returning a valid response before blaming the proxy.
Proxy not available or rate-limited The public CORS Proxy instance may be rate-limited or offline
Run the open-source proxy locally with npm install and node server.js, or deploy it to your own server.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
