Developed a token-usage aware data extraction feature for the 0xPlaygrounds/rig repository, focusing on backend API evolution using Rust. Introduced a new response structure that encapsulates both extracted data and usage metrics, enabling users to monitor token costs directly within their workflows. The implementation ensured backward compatibility by routing legacy API calls through the new usage-tracking methods, allowing seamless integration for existing clients. Enhanced the codebase with integration tests and updated usage examples to validate both new and legacy behaviors. This work supports data-driven budgeting for extraction workloads, providing operators with greater cost visibility and confidence in backend operations.
