The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
trustagent_check_address Check an address (free) ~145
Screen an EVM address, contract or ERC-8004 agent before paying it. Returns a risk band, an OFAC sanctions-list verdict, flag counts and a confidence score. Free — no wallet or payment needed. Use this first for any "is this safe to pay / interact with" question. A sanctions hit is a strong signal warranting review; a miss is not legal clearance.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | EVM address (0x…), an ERC-8004 agentId, or an eip155:<chain>:<registry>/<id> identifier |
| type | string | – | Optional hint about what the subject is. Defaults to auto-detection. |
No output schema declared.
No examples provided.
trustagent_pricing What the paid tools cost (free) ~52
List the paid endpoints, their prices in USDC, and the free-trial allowance. Useful for deciding whether a deeper check is worth paying for, and for explaining costs to a user before spending their money.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
trustagent_resolve_agent Resolve an ERC-8004 agent (free) ~121
Look up an ERC-8004 agent identity: its owner, payout wallet, registration file and a liveness classification saying whether it is a working agent or an unactivated placeholder. Accepts an agentId, an eip155 identifier, or an address that owns an agent. Free. Returns 404 only when the registry index is complete, so an absent answer is never a guess.
| Name | Type | Req | Description |
|---|---|---|---|
| subject | string | yes | agentId (e.g. "60015"), eip155:<chain>:<registry>/<id>, or an owner address |
No output schema declared.
No examples provided.
