Tools (12)

`endpoint_health`	Is 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_payable`	Alphabetical hosts whose index row includes x402. Evidence only. Not a rank and not a payable proof.
`find_provider`	Cheapest 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.
`list_changes`	Newest-first drift. Anonymous: last 5 summaries. Subscriber for that origin: full history.
`lookup_host`	Cached 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.
`participation_check`	Cached participation status and evidence. Not a legal finding.
`pay_preflight`	Can an agent pay at this host? Rails, endpoint, price, freshness. Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.
`payto_check`	Does 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.
`refresh_host`	Paid 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.
`refresh_host_protocol`	Paid 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_batch`	Paid 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.
`verify_receipt`	Did 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.
