Converts a raw EVM address to its EIP-55 checksummed form and returns both lowercase and checksummed variants

Performs a live end-to-end x402 micropayment settlement test, verifying buyer wallet, USDC payment path, and facilitator by returning a timestamped pong only after successful on-chain settlement.

Verifies an x402 payment endpoint before committing funds, checking the payTo address, USDC quote, network, asset binding, TLS, and endpoint safety.

Continuously monitors whether AI agents can discover, call, and pay your API, MCP server, or x402 service over a 30-day window, returning health check results.

Verifies a completed x402 USDC payment transaction on Base mainnet, confirming settlement status, EIP-3009 transfer shape, recipient address, and amount.

Converts EVM token amounts between human-readable decimal and raw base-unit (wei-style) representations for any token with a specified decimal precision.
