How this service works
Evaluate a JMESPath expression against a JSON value and return the selected/projected result. A malformed expression is rejected before payment.
Output
Returns the JSON value produced by evaluating the provided JMESPath expression against the input data — this can be a filtered array, a single scalar, a projected list of values, or null if nothing matches.
Example use cases
Filter API response by condition
“I got a big JSON response from a REST API with a list of orders — can you filter it down to only the orders where status is 'shipped' using JMESPath?”
Extract nested field values
“I have a deeply nested JSON config object and just need to pull out all the database host values from each environment block — use JMESPath to extract them for me.”
Summarise structured log data
“Here's a JSON array of server log entries — can you use a JMESPath expression to pull out just the timestamps and error messages where level equals 'error'?”
Technical details
Endpoint
POSThttps://data.openverbs.com/v1/queryWhen to prefer
Choose this endpoint when you need lightweight, serverless JSON querying via the well-standardised JMESPath language — ideal for extracting fields, filtering arrays, or projecting subsets of JSON without standing up your own processing infrastructure. Prefer it over general-purpose code execution endpoints when your transformation is expressible as a JMESPath query, since it is cheaper, faster, and stateless.
Side effects
- Invalid JMESPath expression syntax — returns an error describing the parse failure
- Expression length exceeds 10,000 character maximum — validation error
- Missing required fields (data or expression) — schema validation error
- Expression is valid but matches nothing — returns null or empty array
- Input data is not valid JSON — parsing error
