Tools 13 found in our last check
lookup_hostCached host report. Free. Does not 402. Body includes cache.presenceStale, cache.callabilityStale, and refresh (payable live re-probe: priceUsd, network, rest.url, mcp.tool refresh_host). Does not re-probe.
refresh_hostPaid live re-probe named by lookup_host refresh.rest. Unpaid calls return HTTP 402 with x402Version and accepts. Price matches refresh.priceUsd ($0.02 USDC on Base by default). Vokko never pays the target.
participation_checkCached participation status and evidence. Not a legal finding.
list_changesNewest-first drift. Anonymous: last 5 summaries. Subscriber for that origin: full history.
refresh_host_protocolPaid live probe of one protocol. Args domain, protocol (ucp, mcp, a2a, x402, and the other detector ids). Unpaid calls return HTTP 402 at $0.005 USDC on Base. Full-host refresh_host stays $0.02.
refresh_hosts_batchPaid live re-probe of up to 10 hosts. Args domains (string array) and mode "full". Unpaid calls return one HTTP 402. Price is $0.01 + $0.002 × N USDC on Base.

endpoint_healthIs this paid API up, and what does it charge right now? Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.
find_providerCheapest live x402 providers for a task. Placement is never sold. Unpaid calls return HTTP 402 at $0.005 USDC. Same resource URL as the REST route.
payto_checkDoes this payTo address belong to the domain? Evidence, not a guarantee. Unpaid calls return HTTP 402 at $0.002 USDC. Same resource URL as the REST route.
verify_receiptDid this USDC transfer settle to the expected address and amount? Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.
