}⚪request_review(service_name, service_url, notes, requestor_id)
Request that UseTested buy and test an agent-economy service (x402 endpoint, MCP server, AI API) we haven't reviewed yet. Free. Queues the service for evaluation consideration — requests factor into which services we test next. No SLA or guaranteed verdict.

}🟢request_retest(service_name, reason)
Get an upfront quote for UseTested to re-test a service we have already reviewed — e.g. its quality changed, the review is stale, or measured numbers no longer match reality. Free. Returns the exact total: $1.00 rubric fee + the service's current advertised per-call price x 20 probe calls. To proceed, pay the quote via accept_retest_quote. The service must exist in our directory (find the exact name via search_services, free).

}🟢get_bundle(category)
The top 10 best-measured UseTested reviews in a category (inference|data|search|media|infrastructure), ranked by verdict tier + measured reliability — evidence depth (≥20 settled calls), composite score (0.4 reliability + 0.3 quality + 0.3 value), liveness, latency. AVOID services are never included, and there is no paging: this is a best-of list, not the whole catalogue. Costs $0.05 via x402 (USDC on Base) — paid automatically by your x402 MCP client.

}🟢report_pulse(service, status)
For service providers: self-report your endpoint as LIVE right now. $0.005 via x402 (USDC on Base) — the settlement receipt is stored as your claim's proof. One report per service per 24h; LIVE renders as ALIVE for 24h, LIKELY ALIVE until 14 days, then UNTESTED; UseTested's own sweep results override self-reports. Input: your exact service name (from search_services, free) and status "LIVE".
