A2A Agent Card

8 of 147 agent-readiness points 5.4% of the agent scoregraded — partial credit agent_card

The provider serves a machine-readable agent discovery manifest at the A2A well-known path (/.well-known/agent-card.json, RFC 8615), advertising its identity, capabilities, skills, endpoint and auth. Weighted above agent_skills despite low adoption for a structural reason: an agent card is the only agent surface in this rubric that CANNOT be derived on a provider's behalf — it is served from the provider's own host or it does not exist. Where mcp_server, agent_skills and agentic_access can all credit an artifact API Evangelist authored, this one is provider-published by construction, and so is immune to the provenance defect that distorts the others.

Move this number. Every provider in the catalog is profiled into a public record at artifacts.apis.io/<provider>/, and each check above names the exact artifact it reads. Publish the artifact, open an issue on github.com/api-evangelist/<provider> pointing at it, and the next scoring run picks it up — no gatekeeping and no fee. The full rubric is at apis.io/rating/, and the Influence plan is the fast lane if you would rather work your own listing through the API — remediation, projections and re-check requests.
