INDIVIDUAL MCP TOOL

buy_observation

Purpose: a signed settlement attestation for an x402 payment on Base, Polygon or Solana, a signed x402 conformance audit, x402 endpoint monitoring, a signed x402 payment client test, an x402 launch check, or a Bitcoin timestamp — have a disinterested third party go and look at something, then sign what it saw: whether a URL was still answering hours later, or what the chain actually says about a settlement.
