What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of x402.ottoai.services controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.

What kind of listing

• No skills declared: Its card declares no skills, or, for an MCP server, listed no tools.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.

Technical agent card

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

Protocol

a2a

Card completeness

a2a.proto v1.0 requires eight top-level fields. This card omits:

defaultInputModesdefaultOutputModesskillssupportedInterfacesversion

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
