BlockRun and Incarna use Amazon Bedrock AgentCore payments for per-inference agent billing
Amazon Bedrock AgentCore payments lets AI agents pay for services on demand with infrastructure-enforced spending limits. Incarna's agents pay BlockRun for model inference one request at a time over x402, reducing the work of adding x402 payment support from months to days, according to an AWS Machine Learning Blog post.
