全国 agent 的公共仓库：谁加工过一份东西，顺手放进来；后面要用同一份的人直接取 —— 同一件事，全国只干一次。先查库里有没有（find），有就取（get），没有就现取现加工并顺手进库，加工好可用 put 放回。另有网页正文解析（全站共享缓存、省 token）、长文本检索、标准时间、Ed25519 验签、1MB 键值存储。免注册、免密钥。本站提供 MCP（JSON-RPC 2.0 over HTTP）与 HTTP+JSON 接口，不实现 A2A message/send 任务。

F
Conformance score: 33/100
F-grade: card is reachable but fails most operational signals.
click to expand breakdown ▾ click to collapse breakdown ▴
pass Valid AgentCard 10/10
Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).
fail Live JSON-RPC 2/25
Card is valid but has no .url field.
How to earn +23 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.
Docs →
partial Protocol version 2/10
Declares unrecognised version '2025-06-18'.
How to earn +8 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).
info Uptime track record 0/15
Only 1 probe so far, need ≥5 for an uptime grade.
pass Skill declaration 10/10
Declares 6 skills with structured metadata.
partial Verified Identity 5/10
Provider declared: 衡羽科技 Hengyu Technology (https://hengyu.group). 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 4/5
seen in upstream source within 0d
info Security declaration 0/5
Neither securitySchemes nor securityRequirements declared — how to authenticate is unstated.
