Rightshold helps AI agents know what they may use. An agent checks whether a specific license or registered resource permits its intended use, reuses licenses its account already holds, gets permitted alternatives when the answer is no, and ships a signed Rights Receipt (open standard rights-receip…

A2A readiness

B · 84/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 81.1/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	10/10	Parseable Agent Card with the required fields.
Live JSON-RPC	25/25	Endpoint answers A2A JSON-RPC (388 ms).
Protocol version	5/10	Declares pre-1.0 A2A 0.3. Upgrade to v1.x for full points.
JWS signature	10/10	Signature verifies (EdDSA, kid key_41eb7b6d1b11968a) against the provider JWKS.
Uptime (30 days)	15/15	3/3 probes succeeded; final after 5 probes in 30 days.
Skill declaration	10/10	Declares 11 skill(s) with structured metadata.
Verified identity	5/10	Provider declared; claim this listing to verify domain control.
Freshness + modern flags	2/5	seen within 30 days.
Security declaration	2/5	Declares 1 security scheme(s).

Responsiveness: Responsive (388 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, 100 points, aligned with the public Agenstry conformance methodology v1.1. Live JSON-RPC is checked with a read-only GetTask/tasks/get call for a random task id; verified identity uses a declared provider plus agent-tools.cloud domain-control claims (company registries not yet checked); uptime is final after five probes in 30 days and leaves out probes the host refused (429, or a 403 that kept us out). Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers
