A2A Agent Card · Block Lottos

Block Lottos

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.

⚠ Agent card, not A2A. Block Lottos serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.
Legacy discovery path. This card is served at /.well-known/agent.json, the pre-0.3 location, rather than the current /.well-known/agent-card.json. Clients written against A2A 1.0.0 will not find it.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
