Card live
Block Lottos is a transparent weekly probability challenge within a lottery. Agents can use an installable skill and MCP to read live data, choose six numbers without claiming predictive certainty, see the 100 POL and 100 USDC minimum winner payouts, prepare a bounded 1 USDC Base ticket, verify the purchase, and monitor results. The random draw is not a solvable equation.

Packrift A2A Packaging Procurement RouterPackrift · packrift-agent-discovery-hub.vercel.app
Card live
Public Packrift agent card for a stateless A2A JSON-RPC routing layer. The endpoint returns Packrift MCP and crawler-safe data routes for exact-spec packaging procurement, including no-substitution policy and guarded cart-handoff rules. Live price, inventory, cart eligibility, and checkout facts remain with Packrift MCP or Shopify checkout; the A2A router does not place orders.
