Make cross-origin API calls without a backend

🔓

Bypass CORS

Any API that blocks browser requests due to missing CORS headers can be reached through the ToolBit proxy server-side.

🌐

All HTTP Methods

GET, POST, PUT, PATCH, DELETE - with a custom request body for POST/PUT and full control over HTTP method.

🔑

Custom Headers

Pass Authorization, API keys, Accept, Content-Type, or any header your target API requires.

💾

API Collections

Save your API requests into named collections for reuse. Organize by project, client, or environment (Pro+).

📊

Response Preview

See the response status, headers, and body formatted directly in the dashboard. No separate API client needed.

🛡️

SSRF Protected

Internal network addresses are blocked. The proxy only forwards to public internet URLs - no access to your infrastructure.

How to use the API proxy

1

Open the API Proxy tab

Log in to your ToolBit dashboard and navigate to the API Proxy tab in the sidebar.

2

Enter your request details

Paste the target API URL, select your HTTP method, and optionally add headers and a request body.

3

Send the request

ToolBit makes the request server-side and returns the full response - status code, headers, and body - to your browser.

4

Save to a collection (Pro+)

Save frequently used requests to a named collection so you can re-run them with one click without re-entering the details.

Frequently asked questions

What is CORS and why does it block API calls?

CORS (Cross-Origin Resource Sharing) is a browser security policy that blocks requests from one domain (e.g. your website) to another domain (e.g. an external API) unless the API server explicitly allows it. Many APIs - especially third-party services - do not set the right CORS headers, so browsers refuse to complete the request. A proxy solves this by making the request server-side, where CORS does not apply.

Is my API key safe when sent through the proxy?

ToolBit does not log request headers or bodies. Your API keys are forwarded to the target and not stored. That said, for production applications with sensitive credentials, making requests from your own backend is always safer than routing through a third-party proxy.

How many requests do I get per day?

Free: 50 requests/day. Starter: 200 requests/day. Pro and Elite: unlimited. Limits reset at midnight UTC.

Can I proxy requests to any URL?

Any publicly accessible HTTPS or HTTP URL. Internal/private addresses (localhost, 10.x, 192.168.x, etc.) are blocked by SSRF protection.

What are API Collections?

Collections let you save named API requests - URL, method, headers, body - and re-run them without re-entering the details. Available on Pro and Elite plans. Think of it as a lightweight Postman or Insomnia built into ToolBit.

Can I use the proxy programmatically?

Currently the proxy is UI-only. Programmatic access via ToolBit's own API is on the roadmap for Pro accounts.
