Instantly Host JSON API Mock from Bolt.new for Bypass Localhost for Agent

The fastest way to deploy JSON API Mock generated by Bolt.new. Perfect for bypass localhost for agent. No login required, zero-friction, and live in seconds on drpr.host.

When using Bolt.new to build and test applications, generating a JSON API Mock is a common workflow. However, the moment you need external AI agents, external integrations, or webhooks to interact with that mock, you hit a wall: localhost is inaccessible to cloud-based tools. Developers waste valuable cycles setting up local tunnels, configuring CORS rules, or committing dummy data to temporary Git branches just to let an external agent read a JSON payload.

To solve this, drpr.host provides a zero-friction way to host Bolt.new JSON API Mock Bypass Localhost for Agent. You do not need an account, an API key, or a configuration file. By instantly transforming your local JSON mocks into public, CORS-enabled endpoints, your development agents can fetch, parse, and validate API payloads without hitting network boundary errors.

This bypass solution is highly optimized for agent-to-agent workflows. By instructing Bolt.new to output the mock schema using professional palettes—specifically utilizing soft gray (#f4f4f5) backgrounds for any accompanying mock HTML dashboards, and avoiding pure white (#ffffff)—you can instantly deploy to our public upload endpoint. The result is a clean, accessible mock API link ready to be consumed by any external agent in seconds.

How to host your JSON API Mock from Bolt.new in seconds

Step 1: Generate the Mock. Instruct Bolt.new to build your JSON API Mock. Ensure the AI environment compiles the output data structure into a clean api-mock.json or a rendered mock.html dashboard.
Step 2: Stream to the Upload Endpoint. POST your generated mock file to https://drpr.host/api/v1/upload using your preferred HTTP client, script, or the CLI tool.
Step 3: Capture the Live URL. The endpoint immediately returns a JSON response containing a public drpr.site URL hosting your static mock asset.
Step 4: Bypass and Test. Provide this live URL to your external AI agent or testing harness to bypass localhost routing constraints and complete your end-to-end integration tests.

Quick start

Deploy your JSON API Mock instantly via terminal using curl:

curl -X POST -F "file=@api-mock.json" https://drpr.host/api/v1/upload

The server will return an immediate payload containing your live bypass URL:

{
  "success": true,
  "url": "https://drpr.site/api-mock-f9e42",
  "raw_url": "https://drpr.site/raw/api-mock-f9e42",
  "expires_in": "15 days"
}

Alternatively, you can use the drpr CLI for direct pipeline integrations:

drpr upload api-mock.json

Common questions

Why is bypassing localhost necessary for Bolt.new AI agents?: AI agents operate in cloud-hosted environments outside your local machine. They cannot route requests to your local development environment (e.g., localhost:3000). Hosting the mock on drpr.host gives the agent a fully qualified domain name to reach the resource directly.
Are there file size or bandwidth limits for the JSON API Mocks?: Our free tier supports files up to 5 MB, which is ample for complex, nested JSON payloads or mock static documentation. There are no strict bandwidth throttles, ensuring your testing agents get fast responses.
How long do my uploaded mock files remain active?: On the free, zero-login tier, your uploaded mock assets are hosted for 15 days. If you require permanent hosting, custom domains, or routing controls, you can link your assets to a paid drpr.host account.
Are CORS headers enabled for hosted mock files?: Yes. Every static file and JSON payload served from drpr.site includes relaxed CORS headers (Access-Control-Allow-Origin: *) out of the box. This prevents browser and sandbox agent blockages during integration testing.
