Agentprobe

Agentprobe is a testing tool that scores the ability of online stores to support AI agents in discovering, quoting, and completing purchases.

Agentprobe tests seller URLs to determine if they are compatible with autonomous AI agents. It evaluates sites based on their ability to facilitate the discovery, quoting, and purchasing process without human intervention. The tool runs 13 specific probes including checks for llms.txt, OpenAPI, ai-plugin.json, MCP, commerce.json, and various APIs for quotes, checkout, and payments. Sites receive a score that categorizes their readiness level, ranging from "NOT_READY" for opaque sites to "CERTIFIED" for fully agent-legible ones. This service helps businesses understand if their digital commerce infrastructure is accessible to AI agents.
