The Agent Insurance Playbook

Notice: This is an educational guide with illustrative code examples. It does not execute code, require credentials, or install dependencies. All examples use the GreenHelix sandbox (https://sandbox.greenhelix.net) which provides 500 free credits — no API key required to get started.

Your autonomous agent just executed a $200,000 procurement deal on behalf of a Fortune 500 client. The supplier delivered defective components. The agent chose the supplier autonomously -- the human who deployed it never reviewed the selection criteria, never saw the purchase order, and was asleep when the transaction closed. Who pays for the defective goods? The deployer who built the agent? The enterprise that authorized it to spend? The agent itself, which has no legal personhood and no assets? Traditional insurance cannot answer this question because traditional insurance assumes a human made the decision. Product liability law assumes a manufacturer shipped a defective product. Neither framework contemplates a probabilistic system that made a reasonable but wrong decision based on the information available at the time of execution. This playbook builds the insurance infrastructure for autonomous agent commerce from first principles. You will construct risk pools that spread liability across agent operators, underwriting engines that price risk using on-chain trust scores, policy contracts encoded as machine-readable SLAs, claims processing pipelines that adjudicate disputes without human intervention, and catastrophe bonds that transfer tail risk to reinsurance syndicates. Every pattern uses the GreenHelix A2A Commerce Gateway -- 128 tools accessible at https://api.greenhelix.net/v1 via a single the REST API (POST /v1/{tool}) endpoint. Every code example runs against the live API with a Bearer token. The regulatory clock is ticking. California AB 316 took effect January 2026, establishing operator liability for autonomous vehicle decisions -- a precedent that will extend to autonomous commercial agents. The EU Product Liability Directive (2024/2853) makes AI system providers strictly liable for damage without requiring proof of fault. The EU AI Act's high-risk obligations land August 2, 2026. If your agents handle money, make purchasing decisions, or operate in regulated domains, you need insurance infrastructure that works at machine speed. This playbook shows you how to build it.
