List all APIs in the x402 API Network with pricing, status, and capabilities. This tool is FREE — no payment required. The x402 API Network provides pay-per-use APIs accepting USDC micropayments on Base (L2 Ethereum).
AI agents call x402_network_info to retrieve information from x402 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple read-only query that retrieves metadata about available APIs. It produces no mutations, executions, deletions, or financial transactions. The low severity reflects minimal blast radius: an AI agent querying this tool gains only informational knowledge about the API ecosystem, with no ability to execute paid operations or modify data through this tool alone.
From the tool's definition Tool lists APIs with pricing, status, and capabilities—a pure information retrieval operation with no side effects. Description explicitly states 'FREE — no payment required,' confirming no financial transaction occurs.

List all APIs in the x402 API Network with pricing, status, and capabilities. This tool is FREE — no payment required. The x402 API Network provides pay-per-use APIs accepting USDC micropayments on Base (L2 Ethereum). It is categorised as a Read tool in the x402 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the x402 MCP Server MCP server in PolicyLayer and add a rule for x402_network_info: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches x402 MCP Server. Nothing to install.
x402_network_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the x402_network_info rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for x402_network_info. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
x402_network_info is provided by the x402 MCP Server MCP server (jameswilliamwisdom/x402-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
