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 →
lumi_check_free Lumi: free signed seller check (cached) ~159
Free. The same label as lumi_verdict from Lumi's record (cached, no live contact with the seller), signed by Lumi: checks_passed, check_first, checks_failed or no_data, with reason codes and an evidence link. Of the URL, only the origin and path are sent; payTo and amount are sent if you pass them. Use lumi_verdict when you want the live check at call time.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string | – | Optional: the quoted price in USD, e.g. 0.01 |
| payTo | string | – | Optional: the payTo address in its 402 quote |

lumi_verdict Lumi: check an x402 seller before paying ~266
Check an x402 seller before you pay it. Pass the resource URL (or the seller's domain) you are about to pay, and optionally the payTo and USD amount from its 402 quote. Returns one label from Lumi Trades' own test-buys and checks: checks_passed (Delivered in recent checks), check_first (Check first), checks_failed (Recent checks failed) or no_data (Not enough data), with as-of date, conclusive test-buy count, last delivered and failed dates, reason codes, evidence and appeal links. label_live is the label after Lumi contacts the seller at call time (an unpaid request) and compares its quote, price, payTo and TLS with Lumi's record. Signed by Lumi. Costs $0.01 per call, paid from your wallet within the configured caps; with no wallet it returns the price quote and pays nothing. Paying Lumi never changes a result. Observations, not a guarantee.
