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
A per-domain report containing: registrar name, creation date, expiry date, days until expiry, registry status flags and locks, nameservers, DNSSEC status, and a risk signal (active, expiring-soon, expiring-very-soon, expired, or at-risk). Failed lookups are not charged and are indicated in the response.
Example use cases
Portfolio expiry audit
“Check these three domains for me — acmecorp.com, acmecorp.net, and acmecorp.io — and tell me their expiry dates, how many days are left, and flag any that are expiring within 60 days as warnings or within 14 days as critical.”
Scheduled alerting for renewals
“I want to monitor mybusiness.com, mystore.org, and myapp.dev for expiry issues — only show me the ones that are expired, expiring soon, or at risk, with a 45-day warning threshold and a 10-day critical threshold.”
Domain due diligence before acquisition
“Before I buy this brand, can you look up the RDAP registration details for targetbrand.com — I need the registrar, creation date, expiry date, registry locks, nameservers, and whether DNSSEC is enabled?”
Technical details
Endpoint
POSThttps://agent-data.centorprat.workers.dev/tools/domain-expiry-registration-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, keyless RDAP-based domain registration and expiry data without setting up a WHOIS API key. It is ideal for monitoring up to 3 domains per call with configurable warn/critical thresholds and a built-in risk signal, making it well-suited for portfolio audits, pre-acquisition due diligence, or scheduled renewal alerting workflows. Prefer it over raw WHOIS tools when you want structured, normalized output including DNSSEC and registry lock status.
Side effects
- Domain not found in RDAP — returned as not-found, not charged
- RDAP registry unavailable or rate-limited — lookup fails gracefully
- Invalid domain format — may error or return no results
- Domain has no expiry date in RDAP (some TLDs omit it) — field absent
- Network timeout on RDAP query — lookup marked as failed
