Axios Validator
Paste an Axios request config or response object as JSON to instantly validate its structure. Checks required fields, HTTP method, URL format, header types, auth shape, timeout, response status, and more. Nothing leaves your browser.

What Gets Validated
Request Config
- url presence —
urlis required (orbaseURLalone is treated as a warning). - method — must be a string and one of the recognised HTTP verbs:
GET,POST,PUT,PATCH,DELETE,HEAD,OPTIONS. - headers — must be a plain object, not an array or primitive. Common anti-patterns (e.g. stringified JSON in
Content-Type) are flagged. - timeout — must be a non-negative number; strings and negative values are errors.
- auth — if present, must contain both
usernameandpasswordstring fields. - responseType — validated against the six values Axios supports:
arraybuffer,blob,document,json,text,stream. - params / data — type-checked; arrays passed to
paramsand non-serialisable values indataare flagged. - unknown keys — any key not in the official Axios config schema is reported as a warning.
Response Object
- status — required integer; validated against the standard HTTP 1xx–5xx range.
- statusText — required string field.
- data — required; type is reported (object, array, string, number, null).
- headers — required plain object.
- config — if present, recursively validated as a request config.
- 4xx / 5xx status — flagged as warnings (valid HTTP responses, not schema errors).
🔒 Privacy & Security
All validation is performed locally using the browser's built-in JSON.parse. Your config data — including any tokens, passwords, or API keys — is never sent to a server. Suitable for validating configs that contain sensitive credentials.
