Find out exactly where a document breaks, with the line and column, instead of a bare parse error.
Validate JSON syntax and optionally check it against a supplied JSON Schema, reporting the failing path.
Input
Send either a text string or a file object. A file is decoded as UTF-8 and must be one of text/plain, application/json, text/csv, text/yaml, application/xml.
Response
The result carries your remaining balance alongside it, so you can track spend without a second call.
{
"valid": false,
"errors": [
"age: 'old' is not of type 'integer'"
],
"error_count": 1,

}
Cost
1 credit per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.
A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.
Parameters
Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
