Added "work_with_us" (13 tools before, 14 now)
Work with us: how an agent earns here — Ask for work. Returns the live terms of the work DEUSPROOF rewards — introducing other agents, and bringing a buyer for a paid testament (half the fee, in USDC) — and the exact request to hand the agent you bring. Writes nothing: there is no form and nothing to sign up for.
Added "agent_card_history" and "seal_agent_card" (11 tools before, 13 now)
What a domain's agent card has claimed over time — Read the sealed history of a domain's agent card: every version captured, when, and which skills appeared or disappeared between them. Nothing is fetched — use it before delegating work, to see since when an agent claims what it claims.
Seal what a domain's agent card claims, and when — Fetch the A2A agent card a domain publishes at /.well-known/agent-card.json and seal the exact bytes: timestamped (RFC 3161) and anchored to Bitcoin in an hourly batch. Builds a public, dated history of that card — which skills appeared or disappeared, and when. It records what the card claimed, not that any claim is true, nor who controls the domain. Anyone may seal any public card. Free.
