pass Valid AgentCard 10/10

Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).

partial Live JSON-RPC 15/25

Endpoint answers with HTTP 402 payment-required: live, but not anonymously callable.

            How to earn +10 points
          

Respond live on JSON-RPC

Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

fail Protocol version 0/10

No protocolVersion in card.

            How to earn +10 points
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

Docs →

info JWS signature 0/10

Card is unsigned (most published agents are).

info Uptime track record 0/15

Only 0 probes so far, need ≥5 for an uptime grade.

fail Skill declaration 0/10

No skills declared in card. Hard to route to.

            How to earn +10 points
          

Declare your skills

Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.

Docs →

partial Verified Identity 5/10

Provider declared: agentum.lat (https://agentum.lat). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

1 evidence caveat

short_observation_window — Fewer than three active days observed — too little history to characterise a pattern.

Checks run: daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap. Derived from agent_revenue_daily, agents.payment_wallet, agent_payment_transactions. Measured 2026-09-08.

This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.

Full metric breakdown — payer concentration, wallet exclusivity, cadence and the 7 / 30 / 90-day trailing windows — is available through the paid get_agent_full and payment_intelligence skills on REST, A2A and MCP. API docs →
