WebSocket Payload Inspector
Inspects pasted WebSocket payload text: when it is JSON, shows top-level keys, byte length, and parsed value; otherwise shows text and byte length. It does not validate JSON-RPC 2.0.
About this websocket payload inspector
Inspects pasted WebSocket payload text: when it is JSON, shows top-level keys, byte length, and parsed value; otherwise shows text and byte length. It does not validate JSON-RPC 2.0 Validates and converts interface schemas client-side without transmitting private endpoint specifications.
API contract & interface schema logic
Inspects, analyzes, and converts HTTP/1.1 and HTTP/2 protocol messages, cURL command strings, and Cross-Origin Resource Sharing (CORS) preflight handshakes in accordance with RFC 7230, RFC 7231, RFC 7540, and RFC 9110. Parses cURL command arguments (-H, -X, -d, -F, --cookie) into native API client code across Fetch, Axios, Python Requests, Go net/http, and Node.js. Evaluates HTTP response headers (Cache-Control, Content-Security-Policy, Strict-Transport-Security) for security and caching compliance.
Worked schema conversion scenario
Scenario: Summarize pasted JSON-like payload text without parsing a WebSocket frame or validating JSON-RPC.
Sample input:
Processing: Try JSON.parse, list top-level keys and count submitted UTF-8 bytes; no network or schema validation.
Illustrative output:
Schema version & syntax constraints
This inspects pasted payload text only. It does not decode WebSocket frames, connect to a socket or validate JSON-RPC 2.0.
API specifications and schema models in WebSocket Payload Inspector reflect OpenAPI and JSON Schema standards. Verify generated schemas against your runtime validator.
Client-side schema processing boundary
Schema analysis and protocol mapping in WebSocket Payload Inspector execute locally in the browser tab without uploading endpoint definitions.

How to use it
- Paste a WebSocket payload as text.
- Attempt JSON parsing; if it succeeds, report top-level keys, UTF-8 byte count and value, otherwise report text and byte count.
- Read the JSON inspection summary.
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.
Can you show an input and its result?+
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.
