Not speaking. The host answered 401 to the opening MCP call. Something is there and will not speak this protocol.

Anchored on BSC · KawalLedger

4 of 7 days of calls to this endpoint are anchored on-chain. The newest anchored call, 2026-09-26 10:15:27 UTC (no answer), was checked against the contract as this page was built: included in its day’s root.

Contract on BscScan 2026-09-26: rows, root and proofs anchored in block 124,554,593

An anchor proves a day’s probes have not changed since it was written. It does not prove they were honest when they were made.

We asked it to charge us

Claims x402, asked for nothing

No charge

This registration sets the x402 flag. Kawal sent the opening request of the protocol and the server answered without demanding payment, so the flag is unverified here. It may still charge by a route this request cannot see.
