AgentIndex Blog
The AgentIndex blog is the notebook behind the directory: notes on the x402 payment protocol, the agent-service economy, and what the listing data actually shows. The flagship series is the State of x402, a quarterly report that reads the directory like a dataset — which categories are growing, where new services are appearing, and how pricing and settlement patterns are shifting across chains and facilitators.
Between reports, shorter posts cover protocol explainers, facilitator news, and methodology notes about how listings are verified and maintained. Everything here is written from the same committed data that powers the directory pages, so a claim in a post can always be checked against the dataset. Subscribe with the RSS feed to get new posts as they publish.
