  x-guidance: 'Zinin M2M Hub — pay-per-call data & tool APIs for AI agents. Each POST /api/{slug} operation below is a distinct paid tool: call GET /api/{slug}/schema first for the exact input shape, then POST with a signed PAYMENT-SIGNATURE header (x402 v2, USDC — see x-payment-info per operation) or omit it to receive a 402 with full payment requirements in the PAYMENT-REQUIRED header. The same catalog is also available as MCP JSON-RPC tool bundles at POST /mcp/{bundle} — see GET /.well-known/x402 for the list of bundles.'
