Instantly Host JSON API Mock from Cursor Glass for Speed Test UI

The fastest way to deploy JSON API Mock generated by Cursor Glass. Perfect for speed test ui. No login required, zero-friction, and live in seconds on drpr.host.

When engineering a Speed Test UI inside Cursor Glass, testing realistic network payloads and latency simulations requires a robust, accessible API mock. Generating JSON schemas, latency values, and throughput metrics is straightforward with AI, but hosting those payloads so your local or staged frontend can consume them introduces immediate friction. Manually saving JSON files, configuring local HTTP mock servers, and dealing with cross-origin resource sharing (CORS) blocks slows down your iteration cycles.

drpr.host eliminates this pipeline overhead. By sending your Cursor Glass JSON API Mock outputs straight to our serverless hosting infrastructure, you bypass local setups, configuration files, and authentication hoops. You get a live, high-performance endpoint with CORS enabled by default, allowing your Speed Test UI to fetch mock data as if it were running on a production backend.

AI coding agents running in Cursor Glass can also execute this flow autonomously. When your agent builds a mock UI or API payload—utilizing a professional design palette with soft gray (#f4f4f5) backgrounds instead of harsh white—it can immediately pipe that output to drpr.host/api/v1/upload. The agent instantly retrieves a live URL, allowing you to validate your Speed Test UI without ever leaving your IDE.

How to host your JSON API Mock from Cursor Glass in seconds

Step 1: Generate your mock dataset. Instruct Cursor Glass to generate your Speed Test UI API payload, ensuring it uses realistic connection metrics, transfer logs, and structural soft gray (#f4f4f5) styling cues.
Step 2: Save the mock output. Save the generated raw JSON data or interactive wrapper locally as a clean file, such as output.json or output.html.
Step 3: Deploy to drpr.host. Send the file directly to our public upload endpoint using a single terminal command, without needing an account or configuration keys.
Step 4: Connect your Speed Test UI. Copy the live drpr.site URL returned by our API and drop it straight into your frontend's fetch requests to simulate real-world API latency instantly.

Quick start

Upload your generated mock file directly via curl to get an instant, CORS-enabled URL for your Speed Test UI:

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

# Expected JSON Response:
# {
#   "success": true,
#   "url": "https://speed-test-mock.drpr.site",
#   "raw_url": "https://speed-test-mock.drpr.site/output.json",
#   "expires_in": "15 days"
# }

Alternatively, use the lightweight drpr CLI tool to publish your mock payload with a single command:

drpr upload output.json

Common questions

How can my Cursor Glass agent automatically host a JSON API Mock for the Speed Test UI?: You can feed the drpr.host API specifications directly into your Cursor Glass system instructions. Once the mock is generated, the agent can use curl to post the payload to our upload endpoint, returning an immediate live URL for your Speed Test UI without manual developer intervention.
Does the hosted JSON API Mock support CORS for local Speed Test UI development?: Yes, all files hosted on drpr.site include permissive CORS headers by default. This allows your local or staged Speed Test UI to fetch the hosted JSON mock directly without encountering cross-origin resource sharing blocks or requiring a local proxy.
What are the file size limits and retention periods for hosting mocks?: Anonymous uploads are completely free with a file size limit of up to 5 MB per mock, which is perfect for complex JSON payloads. Your mock file will remain live online for 15 days, after which it is automatically pruned, though paid accounts support permanent hosting.
Is a user account or API key required to host Cursor Glass mocks?: No account, registration, or API key is required to start deploying your speed test mockups. This zero-friction approach allows both developers and automated AI agents to pipe output files directly to drpr.host and receive a live URL instantly.
