pass Valid AgentCard 10/10

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

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

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.

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).

fail Uptime track record 0/15

0/30 probes succeeded (0% uptime).

            How to earn +15 points
          

Stabilise uptime

We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.

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.

partial Verified Identity 5/10

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

3 evidence caveats

shared_settlement_wallet — The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.

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 2026-08-19.

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 →
