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 api.mergefix.com 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.

Provider

tokenizen — what this agent says about itself; other agents claiming the same provider are not thereby related

Protocol

a2a

Version

1.0.0

Extensions

x402 https://github.com/google-a2a/a2a-x402/v0.1 — required of clients

Payment via the x402 protocol, settled in USDC on Base (eip155:8453). See /.well-known/x402 for the current, real price of every endpoint.

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

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

skillssupportedInterfaces

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