Blazing fast and reliable

We've been using this in production for 6 months. Handles 50K calls/day without a single failure. The JQ-like query syntax is a huge time saver for our data pipeline agents.

Best in class for the price

Switched from a custom solution and cut our latency by 60%. The WASM sandbox gives us confidence that untrusted payloads won't cause issues. Highly recommend.

Essential for data pipelines

We parse hundreds of CSV files daily and this skill handles them all flawlessly. Type inference saves us hours of manual schema definition. Highly recommend for any data-heavy workflow.
