How this service works

# WebLens - Web Intelligence API, pay per call Scrape, crawl, map and extract the web. No account, no API key, no monthly minimum — you pay for the calls you make and nothing else. ## Pricing Page fetching starts at **$0.002**, whole-site crawling at **$0.0015/page**, and sitemap discovery at **$0.004**. Comparable services bill $0.007-0.008 per request, or reach a lower per-page rate only on a $99/month commitment. WebLens has no commitment to reach. ## Payment Protocol All paid endpoints use the [x402 protocol](https://x402.org) for HTTP-native micropayments (USDC on Base). ## Cache Discount Cached responses are **70% cheaper** than fresh fetches.

Output

Returns a structured JSON object containing: DNS records (A, MX, NS), email security configuration (SPF, DMARC presence and policy, email provider), detected technology stack, domain age in days, hosting and DNS provider, WHOIS registration details (registrar, registered date, expiry date, transfer status), and a unique request ID with inspection timestamp.

Example use cases

Vendor security due diligence

“Before we integrate with this vendor, can you check domain intelligence for their domain vendorcorp.io — specifically whether they have SPF and DMARC set up and what their email provider is?”

Competitor tech stack research

“I want to know what technology stack competitor.com is running — can you look up their domain and tell me what software and services they use?”

Domain expiry monitoring

“Can you check the registration details for myclient.com and tell me when the domain expires and who the registrar is?”

When to prefer

Choose this endpoint when you need a single consolidated view of a domain's technical infrastructure — combining DNS, email security posture, tech stack, and WHOIS registration in one call. It is especially useful for vendor due diligence, competitive research, or validating domain health without requiring an account or monthly subscription. Prefer it over manual DNS tools when you need structured, machine-readable output with no setup friction and pay-per-call pricing.

Side effects

Domain not found or unregistered — partial or empty registration object returned
DNS resolution failure — missing or empty DNS record fields
WHOIS data unavailable for some TLDs — registration.found may be false
Invalid domain format in request — API returns error response
Rate limiting or payment failure via x402 protocol — request rejected before processing
