API Client

A local API client built into the Unfour troubleshooting workspace

Unfour includes a local-first API client for building HTTP requests, inspecting responses, and continuing a backend investigation into SSH logs and database state in the same workspace.

It is built for backend developers who need to move from an API symptom to server and database evidence without recreating the request context in separate tools.

A saved request, with its response in view

Open a saved request and inspect its response alongside recent history. Here, the Demo API returns order 1001 with a 200 OK response.

Open full-size image to inspect details

Build, organize, and inspect API workflows

The current API Client covers everyday request work as well as scripts and collection exchange used in repeatable troubleshooting.

Import cURL

Paste a supported cURL command, preview parsed fields with sensitive values masked, and create an unsaved request. Import does not send it.

HTTP request building

Configure methods, URLs, query parameters, headers, request bodies, authentication, and timeouts.

Collections and folders

Save requests in collections and nested folders so a service workflow can be reused instead of rebuilt.

Environments and variables

Resolve workspace and environment variables across URLs, headers, query parameters, and request bodies.

Scripts and OpenAPI

Run pre-request and post-response scripts, review tests and console output, and import or export OpenAPI 3.x collections.

Collection and Environment exchange

Import and export collections in Unfour, Postman, or OpenAPI formats, and environments in Unfour or Postman formats. Preview imports and review format warnings before applying them.

Response evidence

Inspect response bodies, headers, cookies, timing, request details, and saved request/response history.

MCP-assisted API operations

Let an approved MCP client inspect saved requests and history or send a scoped request through Unfour tools.

Connected troubleshooting

Reproduce a failing endpoint, then check the fix

Save the request that returns an error or unexpected payload. Inspect its response, check the related service logs and data, then send the same request again after your fix.

  1. 1. Reproduce request
  2. 2. Inspect response
  3. 3. Check logs and data
  4. 4. Re-run after fix

Local-first scope

Requests run from your local Unfour workspace

Requests execute on your device using its network access. Collection imports cover supported formats; review import warnings for differences from your existing API tool.

Request definitions, environments, and credentials stay local by default.

The local application or local MCP server performs the requested API operation.

Sensitive request and response fields are masked before MCP results are returned.

The developer chooses the request, environment, and next troubleshooting step.
