pass Live JSON-RPC 25/25

Endpoint responds to a negotiated A2A SendMessage probe (answers in ~132 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

pass Uptime track record 15/15

91/91 probes succeeded (100% uptime).

partial Skill declaration 6/10

            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`. We canonicalise these into the global skill taxonomy on next probe.

Docs →

partial Verified Identity 5/10

Provider declared: ArgonautWorks (https://github.com/ArgonautWorks/proofflow-agent). 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.
