Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Protocol: a2a
Version: 0.0.0
Auth schemes: bearer
Extensions: https://github.com/yuanying/fraction-agents/tree/main/docs/extensions/reply/v1
Activate it to get the reply of a completed task also as a data part: a summary of up to three lines, sections of Markdown, and sources.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: complete all eight fields required by a2a.proto v1.0
