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 original partial query, a unique request ID, the timestamp of the search, and an array of suggested full query strings that complete the input prefix.
Example use cases
Typeahead search box suggestions
“I'm building a search bar and the user just typed 'best python libr' — can you fetch autocomplete suggestions so I can show them a dropdown of likely full queries?”
Research query expansion
“I want to research 'machine learning for med' but I'm not sure of the best phrasing — can you autocomplete that and show me what full queries people typically search for?”
SEO keyword discovery
“I'm doing keyword research and I have the partial phrase 'how to start an e' — can you run autocomplete on that and tell me what complete search queries come back?”
Technical details
Endpoint
POSThttps://api.weblens.dev/search/autocomplete?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, AI-powered query completion for a partial search string — especially useful for building typeahead/autocomplete UI components, expanding research queries, or discovering how users phrase searches. Prefer this over a full web search endpoint when you only need suggestion strings, not full page results, and want a lightweight, low-cost call.
Side effects
- Empty or too-short query string returns no suggestions or an error
- Network timeout if the upstream search intelligence layer is slow
- Invalid or malformed POST body returns a 400 error
- x402 payment failure or insufficient USDC balance results in a 402 payment required response
- Rate limiting if too many requests are made in a short window
