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
A JSON object containing the audited URL, a list of issues (each with a message, category such as SEO/performance/security/accessibility, and severity level), numeric scores (0–100) for SEO, security, performance, and accessibility, an ISO timestamp of when the audit ran, a request ID, and a list of prioritized plain-language recommendations.
Example use cases
Pre-launch site health check
“Before we go live, can you audit https://staging.mycompany.com and give me SEO, performance, security, and accessibility scores, plus a list of the most critical issues to fix?”
SEO investigation for underperforming page
“My landing page at https://acme.com/landing isn't ranking well — can you audit it and tell me what SEO issues are hurting it, with severity levels and specific recommendations?”
Competitor site benchmarking
“Can you run a site audit on https://competitor.com and pull back their SEO, performance, and security scores so I can see how our site compares?”
Technical details
Endpoint
POSThttps://api.weblens.dev/intel/site-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, scored breakdown of a website's SEO, performance, security, and accessibility health in a single call. It is particularly useful when you want actionable issue lists with severity ratings and recommendations rather than raw page content. Prefer this over a generic scrape endpoint when the goal is site quality assessment rather than data extraction. The caching discount makes it cost-effective for repeated monitoring of the same URL.
Side effects
- Invalid or unreachable URL returns an error response
- Payment failure via x402 protocol prevents the audit from running
- Timeout if the target site is extremely slow to respond
- Rate limiting if too many audits are requested in a short window
- Cached response returned if URL was recently audited (cheaper but potentially stale)
