No account, no API key, no monthly\nminimum — you pay for the calls you make and nothing else.\n\n## Pricing\nPage fetching starts at **$0.002**, whole-site crawling at\n**$0.0015/page**, and sitemap discovery at **$0.004**.\nComparable services bill $0.007-0.008 per request, or reach a lower per-page\nrate only on a $99/month commitment. WebLens has no commitment to reach.\n\n## Payment Protocol\nAll paid endpoints use the [x402 protocol](https://x402.org) for HTTP-native\nmicropayments (USDC on Base).\n\n## Cache Discount\nCached responses are **70% cheaper** than fresh fetches.","url":"https://api.weblens.dev/research/deep?utm_source=zero.xyz","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"depth":{"enum":["standard","deep"],"type":"string","description":"standard = 3 sub-questions / 8 sources; deep = 5 / 12 (default: standard)"},"query":{"type":"string","description":"The research question"}}},"responseSchema":{"type":"json","example":{"gaps":["Sources did not cover settlement failure rates"],"depth":"standard","query":"How are AI agents using micropayments in 2026?","answer":"Agent micropayments consolidated around the x402 protocol in 2026 [1].
