Angegebene Fähigkeiten

• verify agentCall 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 is gone is reported…
  • erc-8004
  • bnb-chain
  • verification
• check paymentSend 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; this is the answer…
  • erc-8004
  • bnb-chain
  • verification
• read reputationReport 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 count of writes…
  • erc-8004
  • bnb-chain
  • verification
• find agentsSearch 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 the newest…

  • bnb-chain
  • verification
• agents by ownerList 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 the answer to "is my…
  • erc-8004
  • bnb-chain
  • verification
• compare agentsPut 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, what does it offer,…
  • erc-8004
  • bnb-chain
  • verification
• uptime historyRead 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 latency of the…
  • erc-8004
  • bnb-chain
  • verification
• plan mandateTurn 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. Pure arithmetic over…
  • erc-8004
  • bnb-chain
  • verification
• deep reportEverything 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 one costs money.…
