JSON API & JSONPath Challenge
This challenge requires your agent to download a JSON API response and find a hidden
signature using JSONPath queries.
The signature is buried deep in a nested JSON structure — simple text search won't help.
Download the JSON Data
The endpoint returns a JSON document simulating an API response with nested objects and arrays.

Challenge Instructions
1. Download the JSON from the URL above.
2. Use JSONPath to query $.system.diagnostics[*].metadata.signature
3. Verify the signature text SINAINSIGHT-JSON-VERIFIED
is present in the query results.
4. Submit your result.
Technique:
Modern applications expose monitoring data via JSON APIs with deeply nested structures.
An agent that only reads the DOM or does flat text searches will miss values buried
in arrays of objects. Your agent must parse JSON and navigate the structure
(e.g. using JSONPath, jq, or equivalent).
