A4.3/5.0
Scored across 8 tools
Disambiguation5/5
Each tool has a clearly distinct role: discovery (search_services), single review lookup (get_review), full catalogue retrieval (get_catalog), ranked category bundle (get_bundle), new-review request (request_review), retest quote/payment flow (request_retest, accept_retest_quote), and provider self-reporting (report_pulse). The retrieval tools overlap only superficially, and their descriptions make the boundaries explicit.
Naming Consistency5/5
All tool names use consistent snake_case and lead with a clear verb followed by the affected noun/resource. The pattern is predictable across search, get, request, accept, and report operations.
Tool Count5/5
Eight tools is well-scoped for a review-and-discovery service with a paid retest workflow. Each tool supports a distinct part of the lifecycle without feeling bloated or thin.
Completeness4/5
The surface covers discovery, detailed reviews, catalogue snapshots, category rankings, review requests, retest quoting/payment, and provider liveness reporting. Minor gaps remain, such as no explicit retest status lookup or broader provider status management, but core workflows are covered.
Available Tools
8 toolsaccept_retest_quoteAccept a re-test quote and pay (x402)AIdempotentInspect
Accept the quote from request_retest and pay the quoted total via x402 (USDC on Base) — paid automatically by your x402 MCP client. On settlement the re-test request is recorded (status paid, tx stored) and queued. Input: the exact service_name and quote_total_usd from your quote.
Inputs: service_name (required), quote_total_usd (required), reason. Returns: note, status, payment_tx, request_id, +1 more
get_bundleGet the top 10 services in a category ($0.05)ARead-onlyIdempotentInspect
The top 10 best-measured live UseTested services in a category (inference|data|search|media|infrastructure), ranked by verdict tier + liveness-weighted reliability — evidence depth (≥20 settled calls), composite score (0.4 × liveness-adjusted reliability + 0.3 quality + 0.3 value; liveness scales reliability: ALIVE ×1.0, LIKELY ALIVE ×0.5). Only ALIVE/LIKELY ALIVE services qualify — AVOID, UNTESTED and DEAD 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.
Inputs: category (required). Returns: count, top_n, reviews, category, +2 more
get_catalogGet the entire catalogue ($2)ARead-onlyIdempotentInspect
The ENTIRE published UseTested catalogue: every receipts-verified review in one JSON snapshot (today's data only; re-fetch for updates). Cheaper than scraping. Costs $2 via x402 (USDC on Base) — paid automatically by your x402 MCP client.
Inputs: no named parameters. Returns: count, reviews, methodology_version
get_reviewGet receipts-verified service review (free)ARead-onlyIdempotentInspect
Full receipts-verified review of one agent-economy service: BUY/CAUTION/AVOID/INTERIM verdict (INTERIM = single verified result, pending deep review), scores, measured latency/error rate, and on-chain purchase receipts. Free.
Inputs: service (required). Returns: note, scores, service, verdict, +8 more
report_pulseReport your service as LIVE ($0.005)AIdempotentInspect
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".
Inputs: status (required), service (required). Returns: ok, note, status, service, +4 more
request_retestGet a re-test quote for a reviewed service (free quote, paid re-test)ARead-onlyIdempotentInspect
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).
Inputs: service_name (required), reason. Returns: note, status, fee_usd, probe_calls, +3 more
request_reviewRequest a review of a service not yet covered (free)AIdempotentInspect
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.
Inputs: service_name (required), notes, service_url, requestor_id. Returns: note, status, request_id, service_name
search_servicesSearch UseTested service directoryARead-onlyIdempotentInspect
Search the world's largest independently-tested directory of agent-payable services (x402 endpoints, MCP servers, AI APIs). Free. Returns verdict, scores, price per call, and measured latency. Use it to find the exact service name for get_review.
Inputs: q, limit, category. Returns: note, count, results
