FAQPage Schema
How do I reduce token usage when processing large JSON API responses?

To reduce token usage for large JSON API responses, format the structured data into TOON v2.0. This approach achieves 30-60% token savings compared to JSON by prioritizing token efficiency over verbosity.

What is the best way to compress structured tabular data for AI context windows?

The best way to compress structured tabular data for AI context windows is applying TOON v2.0 formatting. It supports tabular, inline, and expanded array types with comma, tab, or pipe delimiters to maximize compression and readability.

How does key folding work for flattening nested objects in data formatting?

Key folding flattens nested objects during data formatting to achieve further compression. By transforming nested JSON structures into a flattened TOON v2.0 format, it minimizes token consumption while retaining the essential structured data relationships.

Can I use TOON formatting for uniform event logs and API records?

Yes, you can use TOON formatting for uniform event logs and API records. The TOON v2.0 specification is designed to compress structured data with uniform structures, such as logs, events, and API responses, freeing up valuable context window space.

When should I not use TOON formatting over standard JSON?

You should not use TOON formatting over standard JSON when readability requires standard JSON verbosity. TOON v2.0 prioritizes token efficiency and compression for large uniform datasets, which may reduce the visual readability of complex structured data.
