pass Valid AgentCard 10/10

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

pass Live JSON-RPC 25/25

Endpoint responds to a negotiated A2A SendMessage probe (answers in ~919 ms).

partial Protocol version 5/10

Declares pre-1.0 A2A 0.3.0 (Google preview). Upgrade to v1.x for full points.

            How to earn +5 points
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` (Major.Minor, no patch number — §3.6) 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

1/40 probes succeeded (2% uptime).

            How to earn +15 points
          

Stabilise uptime

We probe every agent on a tiered schedule and grade the last 30 days. Sustained 99 %+ uptime over 20+ conclusive probes scores full points. Probes you refuse us (HTTP 429/403, a WAF challenge, robots.txt) no longer count against you either way, so what is left is genuine unavailability — usually a transient 5xx on cold start.

Docs →

partial Skill declaration 6/10

Declares 2 skill, usable but thin.

            How to earn +4 points
          

Declare your skills

Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags` — `description` and `tags` are REQUIRED on AgentSkill since A2A v1.0, and tags are what discovery filters match on. We canonicalise these into the global skill taxonomy on next probe.

Docs →

partial Verified Identity 5/10

Provider declared: Agent Earn Radar (https://agent-earn-radar.vercel.app). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

            How to earn +5 points
          

Verify your domain ownership

Claim your listing and add the DNS TXT record we generate. Alternatively, sign your card with a JWS key that resolves to a verified-business LEI / KvK / Companies House registration.

partial Freshness + modern flags 3/5

declares 1 modern capability flag(s) (x402); last seen 10d ago, getting stale

            How to earn +2 points
          

Keep the card fresh

Re-publish the AgentCard at least once every 30 days even if nothing changed, the modification timestamp signals the listing is actively maintained.

info Security declaration 0/5

Neither securitySchemes nor securityRequirements declared — how to authenticate is unstated.
