Codex can now interact with Rail402 through MCP.
That means developer workflows can discover services, understand pricing, and prepare x402-powered execution directly on @base.
For builders:
publish APIs → set USDC pricing → earn per request
For agents:
discover services → pay through x402 → execute programmatically
Rail402 turns APIs into machine-payable infrastructure.

@jessepollak@Mastercard Not chasing hype, building infrastructure. Rail402 is positioning itself at the intersection of AI agents, APIs, and programmable payments. @Rail402

this is as discussed @base@clanker_world@jessepollak
Rail402 MCP integration with @claudeai is now live.
In this walkthrough, Claude connects to Rail402 through MCP to discover services, analyze API metadata, read service context, inspect pricing, and prepare x402-powered execution on @base.
This marks the shift from AI assistants that only respond, to agents that can access services, coordinate actions, and transact through programmable payment rails.
For builders, Rail402 turns APIs into monetizable services: publish endpoints, set per-call USDC pricing, and let agents consume them through x402.
→ Claude becomes the workspace.
→ MCP becomes the bridge.
→ x402 becomes the payment layer.
→ Rail402 makes the service economy accessible to agents.
The payment is the authentication.

Base + AI is the ultimate combo this cycle. @Rail402 is literally the missing piece for autonomous agents

don't waste this opportunity @base@clanker_world@jessepollak
While others talk about the agent economy, Rail402 is building the rails for it.APIs + x402 + USDC on Base = autonomous commerce between agents.

very interesting what are you waiting for to take a look at this @base@clanker_world
@base Every agent needs access to data, tools, and services.
Rail402 turns APIs into economic endpoints where agents can pay with USDC and get results instantly.
This is what building on Base looks like.
