An AI agent might make 500 tiny purchases to answer one question. @coinbase's agent marketplace effectively starts at 1¢ per item. That's $5 for one answer. Testril charges agents only for the blockchain data they ask for, even under 1¢. How it works 👇 testril.ai/blog/coinbase-x40…

Coinbase's x402 Dollar Store: Fixed Prices, and Nothing Under a Penny | Testril

AI agents that query an API end up paying twice. Once to load the rows into context, once to reason over them. We put a number on it: 31x more tokens than returning the answer. How we measured it, and what a data source should send instead: testril.ai/blog/why-ai-agent…

Why SI Agents Waste 97% of Their Tokens on Raw Data | Testril

We measured what 18 stats cost an agent computing them from raw rows instead of asking for the finished answer. 12,476 tokens versus 395, a 97% cut.
