WebSocket Payload Inspector
WebSocket Payload Inspector: Validates JSON-RPC 2.0 protocol specifications, parameter keys, and id properties.
About this websocket payload inspector
WebSocket Payload Inspector — browser-based utility.
How this tool works
Implements client-side WebSocket Payload Inspector operations. Validates JSON-RPC 2.0 protocol specifications, parameter keys, and id properties specifically designed for a real-time chat engineer verifies a json-rpc 2.0 message payload transmitted over a websocket connection.
- cURL Command Tokenization: Tokenizes shell commands, handling quoted strings, multiline backslashes, headers, and multipart form payloads.
- Protocol Semantic Parsing: Maps flags to HTTP method, target URL, query parameters, authorization credentials, and body data.
- Client Code Synthesis: Synthesizes idiomatic programming language constructs with correct asynchronous syntax and error handling.
- Security & Header Diagnostic: Checks for dangerous header combinations such as CORS wildcard '*' alongside credentialed requests.
Worked example
Scenario: A real-time chat engineer verifies a JSON-RPC 2.0 message payload transmitted over a WebSocket connection.
Sample input:
Processing: Validates JSON-RPC 2.0 protocol specifications, parameter keys, and id properties.
Illustrative output:
Limits and verification
Handles escaped quotes inside body strings correctly. Flags invalid HTTP methods and unsupported command-line arguments. Does not execute live HTTP requests against external endpoints from this browser session.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

How to use it
- Enter, paste, or select your input data into the WebSocket Payload Inspector workspace controls.
- Review available parameter fields, units, formats, or options configured for your task.
- Click the action button or observe immediate live calculations rendered in your browser runtime.
- Inspect the resulting output and any diagnostic messages, then copy or download the result if needed.
Frequently asked questions
What does WebSocket Payload Inspector return?+
It trims the payload, first attempts JSON.parse, and returns format json, top-level object keys, UTF-8 byte length and parsed value. When parsing fails it returns format text, byte length and the original trimmed text.
What did the WebSocket fixture verify?+
The JSON payload {"ok":true,"name":"Ada"} returned format json, keys ok and name, byte length 24 and the same parsed object. The byte count is for UTF-8 encoded submitted text.
What are the JSON and payload boundaries?+
Only top-level object keys are listed; arrays, scalars and null have no object keys. It does not decode binary frames, compression, CBOR, protocol buffers, fragmented frames, close codes, masking or nested schema validity.
Does inspection observe a WebSocket connection?+
No. It examines a typed payload only. It does not connect, send, receive, authenticate, preserve frame bytes, prove a server protocol, or reveal production traffic.
