It runs a headless browser on the server side so callers need no browser infrastructure. Payment is $0.02 USDC per call on the Base network, settled via the x402 protocol.\n\nThe `/visual/screenshot` endpoint accepts a target URL and returns a JPEG or PNG image. Callers can customize viewport dimensions (320–3840 × 240–2160), enable full-page scroll capture (up to 32,768 px height), choose JPEG quality (1–100), toggle dark mode, block ads and cookie banners, target a specific CSS selector, or emulate device presets (iphone_15, pixel_7, ipad_pro). The sibling `/visual/pdf` endpoint converts a URL to PDF with optional ad blocking.\n\nThe service exposes a full OpenAPI 3.1 spec at `/openapi.json` and a health endpoint that reports browser status, semaphore slots, in-flight requests, cache stats, and uptime. Alternative access methods include an MCP gateway at `mcp.hugen.tokyo`, a free API-key flow (POST to `discovery.hugen.tokyo/keys/create`), and a Python SDK (`pip install x402-pay`). The x402 challenge was captured successfully, confirming the endpoint is live.","tags":[],"capabilities":["url-screenshot","full-page-capture","pdf-export","viewport-customization","device-emulation","dark-mode","ad-blocking","css-selector-capture","jpeg-output","png-output","x402-payment","base-network-usdc"],"categories":["vision","web-capture"],"synonyms":["webpage screenshot API","URL to image","website capture","page screenshot service","URL to PDF","headless browser API","web rendering API","screen capture endpoint"],"warnings":["Response schema for /visual/screenshot is empty in the OpenAPI spec; the example response structure is inferred from the x402 challenge payload.","No documentation on authentication-based page capture (cookies, sessions).","Root URL returns 404; documentation is only at /docs."],"endpointUrl":"https://visual.hugen.tokyo/visual/screenshot","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"10000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"Hc3sdEAsCGQcpgfivywog9uwtk8gUBUZgsxdME1EJy88"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"10000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.820","qualityRationale":"Full OpenAPI 3.1 schema with detailed parameter constraints, live x402 402 challenge confirming the endpoint works, clear pricing ($0.02 USDC on Base), and a sample response structure.
