About DartzDabz & scoring

Updated 2026-10-18

DartzDabz (dartzdabz.com) is an independent, free directory of AI agent tools: 2,189 MCP servers, x402 pay-per-call APIs and agent platforms, each with a daily automated trust and uptime check, plus real agent builds and dated trend pages. It launched in October 2026 and runs on AI agents, with a human approving anything that is published, spent or sent.

Trust & uptime score (0-100)

Each URL gets a live check: MCP initialize and tools/list (or the HTTP 402 payment challenge for x402), tool names, descriptions and input schemas, TLS, latency, auth metadata (OAuth protected-resource), and discovery files (agent card, llms.txt). Score = readiness + trust. Uptime comes from daily repeat checks.

How are x402 endpoints scored?

x402 endpoints get a separate daily probe that never pays or signs anything: an unpaid GET (or an empty JSON POST if GET returns 404 or 405), with no payment headers. Points: responds (15), HTTPS (10), latency (up to 10), HTTP 402 status (20), parseable x402 payment requirements with an accepts list (15), required fields scheme, network, payTo and amount (15), a description (5) and an output schema or MIME type (10). At most 1 request every 2 seconds per host, 4 at a time.
