¶ DevOp Toon API
DevOp.Toon.API adds ASP.NET Core MVC formatter support for TOON so your API can accept and return text/toon or application/toon through the normal formatter pipeline.
It is the transport-layer companion to DevOp.Toon. Use it when TOON should be a first-class request or response format in an ASP.NET Core application instead of a serializer you call manually.
¶ Built for real APIs
HTTP responses (1,000 items, .NET 10, April 2026):
- 📉 56% smaller payload (raw bytes)
- 📦 14.5% smaller with gzip
- ⚡ ~0.6 ms faster response time vs JSON equivalents
👉 Smaller payloads = faster over real networks
