verify_agent

Call an agent's declared endpoint right now and report what answered. This is a live handshake made by Kawal, not a reading of the registry: an agent whose registration declares MCP but whose endpoint…

check_payment

Send the opening request of the x402 protocol — no payment header — and report whether the server actually demands payment. `x402_supported` on the registry is a flag a registration sets about itself;…

read_reputation

Report who wrote an agent's ERC-8004 feedback, not how much of it there is. A sample of 1,200 BSC records came from 53 addresses, one of which wrote 265 of the oldest 600, so a count of records is a c…

find_agents

Search the BSC roster by describing the problem rather than naming a product, and get back agents ranked with Kawal's evidence attached. Duplicate registrations are collapsed: roughly two thirds of th…

agents_by_owner

List the agents one wallet registered on BSC and call each of their declared endpoints now. Nothing on the chain tells an owner their endpoint went dark — the registry keeps listing it — so this is th…

compare_agents

Put two or three agents side by side and answer the same questions of each — the ones a buyer weighs before handing over a spend cap: can it be hired, does it answer right now, has it kept answering, …

uptime_history

Read the history Kawal keeps of one agent's endpoint without dialling it: how many times it was called, how many times it answered in the protocol it declared, since when, and the median and worst lat…

plan_mandate

Turn a capital amount and a duration into the four scoped sessions Kawal would grant on Altana — one per seat, each with its own contract allowlist, spend cap and expiry — without granting anything. P…

deep_report

Everything Kawal holds about one agent in a single answer: the live handshake, the full probe history, how the endpoint fails when it fails, whether it really charges, and who wrote its feedback. This…

taxonomy

The five categories Kawal files agents under — four seats plus security — with the seat each fills, the search query that finds it and the terms that classify it. 8004scan has no category field; this …

kawal://taxonomy
venues

Every contract a seat may be allowed to call, with the chain it is proven on and what the identity call returned; and the four seat policies — cap share, period, venues, priority — that plan_mandate b…

known-defects

The defects of the probing method, published with every uptime record Kawal writes into the ERC-8004 reputation registry. Read this before treating a failed probe as a verdict.

hire_under_cap

Walk through hiring from the BSC roster the way Kawal does it: search by the problem, call the candidates, compare the evidence, read who rated them, and plan the spend cap before anything is granted.
