Zambo
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.

Verify a receipt verify_receipt
Check a Zambo receipt: recompute the sha-256 digest of the exact saved bytes and confirm the saved result was not changed since it was saved. A verified receipt does not prove the answer was right. Served over MCP at https://zambo.dev/mcp and on the web at https://zambo.dev/verify/.

Publish a client-ready handover from a session's receipts: one link that carries the work, its context, and a receipt trail the client can check. Backed by the handover, handover_status, and handover_accept MCP tools at https://zambo.dev/mcp.
