Tools
| Tool | Description | Behaviour |
|---|---|---|
| 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. | Not declared |
| find_payable | Alphabetical hosts whose index row includes x402. Evidence only. Not a rank and not a payable proof. | Not declared |
| 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. | Not declared |
| list_changes | Newest-first drift. Anonymous: last 5 summaries. Subscriber for that origin: full history. | Not declared |
| 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. | Not declared |
| participation_check | Cached participation status and evidence. Not a legal finding. | Not declared |
| 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. | Not declared |
| 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. | Not declared |
| 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. | Not declared |
| 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. | Not declared |
| 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. | Not declared |
| seller_trust | Observational x402 seller trust score for a payTo and network. Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route. | Not declared |
