Core Guide

@wasit-dev/core is the check suite behind the wasit CLI and the MCP server — the actual x402/MPP conformance logic, not a thin wrapper around something else. The CLI and the MCP server are themselves thin adapters over these same functions, so a CLI run and an agent's run against the same target can never disagree — there is only one implementation of each check.

Most people should reach for the CLI or the MCP server instead of this package directly. Install @wasit-dev/core yourself only if you're building your own tooling on top of the check suite — a CI gate, a dashboard, a different front end entirely.

Testnet only. Several checks settle real transactions on-chain.
