Returns cryptographically signed market open/close receipts for 28 global exchanges including NYSE, NASDAQ, LSE, and JPX. Each response includes an Ed25519 signature you can verify independently, with a 60-second TTL and fail-closed behavior (unknown states default to closed). Exposes 5 MCP tools and 25+ REST endpoints from a Cloudflare Worker deployed to 300+ edge locations. Handles DST transitions, lunch breaks, and holidays through 2027. Useful when autonomous agents need verifiable market state before executing trades, or when you need a single source of truth for exchange hours without polling multiple vendor APIs or maintaining your own calendar logic.
