Cian Endpoint Audit

cian-x402.netlify.app · 2 paid endpoints · listed 2026-10-27

DNS and email-authentication audit for one domain: A/AAAA presence, NS count and whether the nameservers share a /24, MX (including a null MX), SPF (missing, multiple, +all, ~all, ?all), DMARC (missing, p=none, no rua, partial pct), a DKIM selector probe, CAA, and whether the zone is DNSSEC-signed. Read entirely over DNS-over-HTTPS, so nothing is sent to the target host. Every finding carries a stable id, a severity and a fix.

Claim it for free with x402_provider_claim (sign with your payout address), and get an alert within minutes when it stops answering with x402_monitor_create ($5 for 30 days). Both work over MCP (https://logicnodes.io/mcp/v2) or POST https://logicnodes.io/v1/tools/<tool>.

Income is all USDC received by the provider's payout address on Base, whatever the source. Score: 0-100: 50 x share of checks in the last 72 h that returned valid x402 payment terms + 30 x min(1, log10(1 + USDC received in 7 days) / 4) + 20 x min(1, log10(1 + distinct payers in 7 days) / 3). A provider never checked scores on income only; income is all USDC received by its payout address on Base, whatever the source. JSON: /v1/observatory/providers/cian-x402.netlify.app
