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 →
catalog.call Run an Agent402 tool ~132
Call any Agent402 tool by slug (find slugs with catalog.find or catalog.search). Payment is handled automatically: USDC via x402 if this server has a wallet key, otherwise free proof-of-work on eligible pure-CPU tools (no wallet needed). Wallet-keyed highlights: live search/answer, stock-quote, render, transcribe, memory, and the /v1 LLM gateway tiers.
| Name | Type | Req | Description |
|---|---|---|---|
| params | object | – | Tool input parameters, matching the tool's inputSchema |
| slug | string | yes | Tool slug from catalog.search, e.g. "search" or "unit-convert" |
