Tools
| Tool | Description | Behaviour |
|---|---|---|
| accept_retest_quote | 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. | Changes data |
| get_bundle | Every receipts-verified UseTested review in a category (inference|data|search|media|infrastructure), sorted by reliability. Costs $0.05 via x402 (USDC on Base) — paid automatically by your x402 MCP client. | Read-only |
| get_review | 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. | Read-only |
| request_retest | 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 10 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). | Read-only |
| request_review | 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. | Changes data |
| search_services | 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. | Read-only |
