Problem
Why this project exists
Autonomous agents need reliable market data without accounts, subscriptions, or permanent API credentials. Raw order-book data also needs interpretation before an agent makes a trade.
Approach
System design
The Rust service reads StablecoinDEX state through RPC. It evaluates spread and liquidity risk. The Machine Payments Protocol protects paid endpoints.
Result
Current release
The prototype provides paid quote, pair, risk, and insight endpoints on Tempo Moderato. A free dashboard shows service activity and payment flow.
