How this service works
Extract one or many values from a JSON blob by dot/bracket path (e.g. items[2].name, meta.total). Pull just the fields you need instead of shipping the whole object.
Output
Returns the extracted value(s) corresponding to the provided dot/bracket path(s) — could be a string, number, boolean, array, or nested object depending on what the path resolves to. Returns only the requested fields rather than the full JSON payload.
Example use cases
Pull nested API response field
“I got a huge JSON back from a payment API and I just need the value at result.transaction.id — can you extract that specific field for me?”
Read array element from JSON
“I have a JSON object with an items array and I need the name from the third element — extract items[2].name from this blob please.”
Grab multiple fields from JSON at once
“From this API response JSON, can you pull out both meta.total and meta.page for me so I know the pagination info without parsing the whole thing?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/jsonpath-extractWhen to prefer
Use this endpoint when you have a large or complex JSON payload and only need one or a few specific values — it avoids transmitting or processing the full object. Ideal for post-processing API responses inline inside an agent workflow when you know the exact path to the data. Prefer this over general-purpose JSON parsing when you want a lightweight, cost-effective extraction step without writing code.
Side effects
- Path not found in JSON — returns null or an error if the specified key or index does not exist
- Malformed JSON input — error if the input blob is not valid JSON
- Invalid path syntax — error if the dot/bracket expression is not parseable
- Type mismatch — accessing an index on a non-array or a key on a non-object node
