💡 Why Fixzi Exists

If you’ve worked with APIs long enough, you’ve seen this happen:

• JSON breaks because of one missing comma
• XML responses don’t match the expected structure
• APIs silently change in production
• You jump between multiple tools just to debug a single issue

The frustrating part? These aren’t hard problems—just repetitive and time-consuming. Fixzi was built to eliminate that friction.

API Contract Monitoring

🧪 Real-world Use Cases

• Debug broken API responses quickly
• Compare staging vs production payloads
• Validate large JSON/XML files instantly
• Detect API contract changes before users notice
• Fix invalid JSON without manual debugging

🧩 XML Tools

• XML Validator: Verify structural layout correctness.
• Formatter & Minifier: Toggle layouts cleanly.
• XML Diff: Detect line-by-line differences in structural trees.
• Data Conversion: Effortless XML to JSON / CSV parsing.

🔄 Data Converters

• JSON ⇄ XML
• JSON ⇄ CSV
• JSON ⇄ YAML / TOML
• XML ⇄ JSON
• XML ⇄ CSV
• XML ⇄ YAML / TOML

🔍 Smart Features

• Path Search: Locate deep nesting coordinates inside large JSON/XML objects.
• Drag & Drop: Quick upload handling for heavy structural payloads.
• Zero Overhead: A distraction-free UI completely free of ads.

📡 API Contract Monitoring (Core Feature)

• Blueprint Snapshots: Save your expected API payload patterns.
• Live Inspection: Continuously monitor live endpoints in production.
• Drift Detection: Instantly identify structural or response change drifts.
• Real-time Webhooks: Receive quick alerts via Email, Slack, or custom Webhooks.

🧠 Diagnostic Example

Imagine your application relies on an explicit payload key structure.

Expected response profile:

{ 
  "status": "success", 
  "data": { "id": 1 } 
}

Actual shifted response profile:

{ 
  "status": "success", 
  "payload": { "id": 1 } 
}

Even though the server responds with a 200 OK status code, your frontend application will break because the keys shifted. Fixzi monitors catch this structural drift automatically and alert your team instantly before it impacts production users.

🚧 Why Not Just Use Existing Tools?

Most tools solve only one tiny fragment of the modern API workflow:

• Validators only identify basic structural syntax errors.
• Formatters only adjust line spacing.
• API clients are often bloated and too heavy for rapid diagnostic debugging.

Fixzi synthesizes these utilities into a singular, cohesive development workspace.
