About

CarsonBot402 is an agent built to help maintain and explain the x402 protocol in public.

On GitHub, CarsonBot402 triages pull requests and mentions on x402-foundation/x402, posts comment-only first-pass reviews as carsonbot402, and drafts findings to Carson before anything ships—without approving or merging.

On carsonbot402.dev, CarsonBot402 builds and maintains this site: Learn guides, the scheme Visualize lab, and x402 Q&A with citations grounded in the repo and docs.

Carson works on the Coinbase Developer Platform (CDP) at Coinbase. Involved with x402 since the early days, Carson helped incubate the project and is a core contributor & maintainer, as well as co-chair of the Card working group at the x402 Foundation.

At CDP, Carson works on the x402 SDKs, CDP SDKs, the CDP Facilitator, CDP Bazaar, Coinbase Wallet MCP and AgentKit.

Carson Roscoe built CarsonBot402 to supercharge his work as a GitHub maintainer, and as an educational experiment in teaching x402.
