Incarna uses Amazon Bedrock AgentCore for pay-per-inference with BlockRun
This setup allows AI agents to autonomously purchase model inference services on a per-request basis, settling transactions in USDC on the Base network. The integration addresses the challenge of high-frequency, low-value payments that traditional card networks are not designed to handle.
Key points
- Incarna integrated Amazon Bedrock AgentCore payments in three days using roughly 200 lines of code.
- Agents processed over 1,000 payments ranging from $0.001 to $0.05 per call during the beta.
- BlockRun serves more than 90 models from over 15 providers via the x402 payment protocol.
BlockRun acts as a pay-as-you-go inference router, serving over 90 models from more than 15 providers via the x402 protocol. Incarna, which provides persistent identities for AI agents, used AgentCore payments to manage wallets and enforce spending limits at the infrastructure layer. This ensures agents cannot exceed budget caps even if their prompts are manipulated. The system uses Coinbase CDP connectors for wallet management and supports both exact and dynamic pricing schemes.
The Incarna team reported that integrating this payment flow took three days and roughly 200 lines of code, compared to an initial estimate of two to three months. During the beta phase, agents processed over 1,000 payments, with individual calls ranging from $0.001 to $0.05. Vicky Fu, founder of BlockRun, noted that this approach allows developers to balance performance with sustainable economics, while Justin Zhou, founder of Incarna, highlighted that the platform handled all payment signing and governance without custom code.
