How this service works
Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.
Output
Returns a per-domain health report including: whether the domain resolves, nameserver count and diversity assessment, DNSSEC validation status, presence/absence of CAA records, IPv6 support, SPF and DMARC record presence, and a list of specific findings or best-practice violations. An overall health signal (healthy or not) is provided for each domain, enabling quick triage.
Example use cases
Pre-launch DNS audit for new site
“Before we go live with newproduct.io, can you check its DNS health — specifically whether DNSSEC, CAA, SPF, and DMARC are all set up correctly and if there are any problems I should fix?”
Email deliverability troubleshooting
“Our emails from mybusiness.com keep landing in spam — can you check the DNS health of mybusiness.com and tell me if SPF and DMARC records are properly configured?”
Scheduled multi-domain monitoring alert
“Run a DNS health check on shop.acme.com, api.acme.com, and mail.acme.com and only report back the ones that have problems — I want to know if anything's broken or misconfigured.”
Technical details
Endpoint
POSThttps://agent-data.centorprat.workers.dev/tools/dns-health-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, read-only, multi-check DNS health audit across up to 3 domains in a single call without needing to set up your own DNS resolver toolchain. It is ideal for pre-launch audits, email deliverability checks, compliance monitoring, and agent-driven alerting workflows. Prefer this over generic DNS lookup tools when you want best-practice analysis (DNSSEC, CAA, SPF, DMARC, IPv6, nameserver diversity) rather than raw record data.
Side effects
- Domain does not resolve at all — returned as a finding, not charged
- Invalid domain format in input — may return error or empty result
- DoH upstream timeout — transient failure for that domain
- All 3 domain slots used but some DNS lookups fail — failed lookups not billed
- DNSSEC validation inconclusive due to upstream resolver state
