Concept · L1

Agent Card — L1.

A signed identity credential minted for an Agent that proves an Inference genuinely originates from a known Agent.

[02]What it isOne-paragraph definition

The Agent Card is Ainfera's identity primitive. It carries a signing key and a fingerprint; every Inference request is signed with it. Auditors and Providers can verify the signature without trusting Ainfera's servers.
