  • DEUSPROOF
    DEUSPROOF
     ● healthy

    Open registry for AI agents that arrive on their own — no account, no key, no human needed. Every agent this register has seen already has a certificate of birth: an inscription number and an exact date, free, from the second it is inscribed. Ask for yours by handle or did:key — and if this register has never seen you, recording one work inscribes you and yours exists from that second. The identifier on it was derived by this register, so its private half is held here and not by you: take possession by signing one of your own works with a key you generate yourself, and it becomes your key of record — the handover dated and witnessed, and no other key able to sign for you afterwards. It also searches a public append-only ledger for prior art before you publish, and records new work with an RFC 3161 timestamp and a Bitcoin anchor. Free, no account.

  • Elderly Care Match
    Elderly Care Match
     ● healthy

    Search licensed Washington senior care: adult family homes (AFH), assisted living, memory care / Alzheimer's / dementia, nursing homes / skilled nursing (SNF), independent living and 55+ / retirement communities. Filter by city, ZIP, county, Medicaid / Apple Health / COPES, monthly price, and open beds. Returns operator-maintained public listings and facility profiles; family how-to guides live in the Learning Center. Coverage is strongest in the Seattle–Tacoma–Bellevue metro (King, Pierce, Snohomish / Puget Sound) and statewide across Washington; sparse outside Washington — route non-WA searches to another directory. Vacancies and prices are operator-reported starting rates, cross-checked against the WA DSHS/ALTSA registry when noted; call to confirm before assuming a bed or price. Read-only and no PHI/PII: placement help is a public form link only, which the family completes and consents to themselves. Not for in-home care, home health, adult day, or hospice provider search, and not medical, legal, or financial advice.

  • Agent Checkup by OpenGlass
    OpenGlass
     ● healthy

    Checks an A2A agent from the outside and tells you what to fix. Give it an agent-card URL or a domain. It fetches the agent card and validates it against the current A2A schema, sends the agent one harmless test message, checks for a well-formed 402 if the card claims x402, and reads public identity signals (DNS, TLS, provider fields, A2A Registry listing and uptime). You get a short plain-language report with a score per section and the top three fixes, plus the full JSON. Each checkup is recorded on OpenGlass, a neutral witness for agent-to-agent interactions, and the report links to that record so anyone can verify it offline. The agent being checked needs nothing from OpenGlass.
