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.

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

info JWS signature 0/10

Card is unsigned (most published agents are).

info Uptime track record 0/15

Only 3 probes so far, need ≥5 for an uptime grade.

partial Skill declaration 6/10

Declares 1 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`. We canonicalise these into the global skill taxonomy on next probe.

Docs →

partial Verified Identity 5/10

Provider declared: SYNTHORA (https://hergertsynthora.com). 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.

pass Freshness + modern flags 5/5

declares 1 modern capability flag(s) (x402); seen in upstream source within 1d

partial Security declaration 2/5

Declares 1 security scheme(s) but none use PKCE or mTLS.

            How to earn +3 points
          

Document securitySchemes

Add a `securitySchemes` block to the card describing your auth: `bearer`, `apiKey`, `openIdConnect`, or `mutualTLS`. Routers refuse to call agents that declare no auth model.
