JSON Path Evaluator

JSONPath is a query language for JSON, similar to XPath for XML. A path starts at the root ($) and walks into the data: dots and brackets select keys and array indices, [*] is a wildcard, .. is recursive descent, and a bracketed filter expression keeps only items that match a condition. This evaluator returns every matching value.

No — the query runs entirely in your browser, nothing is uploaded. As an EU-built, EU-hosted provider, Uptimeify keeps your workflow off US infrastructure and clear of US Cloud Act exposure, which matters for agencies handling client data under GDPR.

When you monitor an API, you often care about one value deep inside a JSON response. Build the JSONPath here to pinpoint it, then use it in an Uptimeify content check that asserts on exactly that field — and alerts you when it changes or disappears.
