June 23, 2026, (Inside AI) — Ampersend, a management platform by Edge & Node, has built a pay-per-intelligence routing layer using Amazon Bedrock AgentCore Payments, enabling AI agents to autonomously pay for model services without custom billing infrastructure. The integration, completed in under two weeks, leverages the x402 open protocol to let agents route tasks to optimal models, pay per request, and operate within set budgets.
This addresses a critical gap in agentic AI: how autonomous agents transact for paid APIs, LLMs, or data endpoints without developers building wallet management, credential handling, and payment orchestration from scratch. AgentCore Payments provides managed wallet infrastructure, spending governance, and native x402 settlement, while Ampersend offers a single integration point to a marketplace of model providers, handling routing and settlement.
Kevin Jones, who led the integration, said:
"Building multi-agent systems is genuinely complex, and we expected payment infrastructure to be the hardest part of the entire project. AWS AgentCore Payments completely changed that. The integration across a buyer agent with AgentCore, a seller agent with Ampersend, and BlockRun AI for pay-as-you-go LLM inference came together far more smoothly than we anticipated. We wired up the logic and it just worked."
Rodrigo Coelho, CEO of Edge & Node, added:
"We built ampersend to be the control layer for agent payments. AgentCore Payments was a natural fit -- managed wallets, spending guardrails and x402 settlement let us demonstrate fully autonomous agent-to-agent micropayments in a matter of days."
How the Two-Hop Payment Architecture Works
The system uses a two-hop payment flow: an agent sends a task to Ampersend, which returns an HTTP 402 payment required response. The agent then calls AgentCore's ProcessPayment API with x402 details, and AgentCore signs a USDC authorization using a connected wallet from Coinbase Developer Platform. The agent never touches private keys.
Key components include a Payment Manager defining wallet connections and policies, a Payment Session with a budget cap (e.g., $0.05), and the ProcessPayment API handling signing. Settlement occurs on-chain via Base network, first from agent to Ampersend, then from Ampersend to the upstream model provider like BlockRun, all transparent to the agent.
AgentCore enforces session-level budgets at the infrastructure layer. If a budget is exhausted, payments are rejected cleanly, giving agents autonomous operation within deterministic boundaries. The platform also provides observability through unified logs and metrics, eliminating separate payment monitoring.
Ampersend's catalog organizes models by capability tier, allowing agents to select based on task complexity. This abstracts away provider complexity, letting builders focus on agent logic rather than payment plumbing. The team estimated that without AgentCore, building wallet custody and spending controls alone would have taken 3–4 months.
The integration supports both v1 and v2 of the x402 protocol, ensuring compatibility with various paid endpoints. Developers can get started by setting up AgentCore Payments via its CLI quickstart, integrating with Ampersend's API at ampersend.ai, and exploring hands-on workshops and samples on GitHub.
