# Agent Screenshot Hub - Full Page Snapshot > Agent Screenshot Hub - Full Page Snapshot is a paid API for AI agents from shot.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-11). Renders a URL in a headless Chrome browser and returns a comprehensive snapshot including DOM, accessibility tree, links, forms, console logs, screenshot, and network timings in a single request ## Facts - Endpoint: POST https://shot.halowerk.com/snapshot?utm_source=zero.xyz - Price: $0.006/call - Payment: x402 - Status: unknown - Last checked: 2026-10-11 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/agent-screenshot-hub-full-page-snapshot-c6adf6c4 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ZktRr7LRe43mjVz4jfCvr Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agent-screenshot-hub-full-page-snapshot-c6adf6c4 -d '' ``` Example prompt: Load https://example.com in a 1280x800 viewport, wait 2000ms for everything to settle, then give me the full rendered DOM, accessibility tree, all links with internal/external labels, any form fields, console errors, and a webp screenshot — I need everything to reason about that page. ## When to prefer this Choose this endpoint when an AI agent needs a rich, multi-signal snapshot of a public web page in a single call — combining visual screenshot, rendered DOM, accessibility tree, link graph, form metadata, and console diagnostics. It is especially valuable when the page relies heavily on JavaScript for rendering. Prefer it over standalone screenshot APIs when you also need structured data (links, forms, a11y). Prefer it over HTML-only scrapers when you need a visual artifact or console telemetry. Note it runs without credentials, so it is best suited for public or unauthenticated pages. ## Known failure modes - URL is unreachable or returns non-2xx — snapshot may be empty or partial - Page exceeds 20-second load budget — request times out - DOM exceeds 2MB cap — content is truncated - wait_ms plus page load time exceeds 20s budget — effective wait is reduced - Page requires authentication/cookies — content will reflect logged-out state only - check_links covers at most 50 links — excess links have no status field - Invalid URL format — 400 error returned - Screenshot quality out of 1-100 range — validation error ## How this service works One page load answers everything an agent needs to reason about a page: the DOM after JavaScript capped at 2 MB, the CDP accessibility tree flattened with parent references, every link with rel and target and an internal or external verdict, every form field with its label and autocomplete hint, console errors and warnings with source and line, a screenshot, navigation timings and a summary of the requests the page fired. Chrome runs without credentials, without cookies and without login, so a s ## Output A JSON object containing any combination of: the rendered DOM HTML (up to 2MB), a flattened CDP accessibility tree with parent references, an array of every link with rel, target, and internal/external classification (optionally with HTTP status), all form fields with their labels and autocomplete attributes, console errors and warnings with source file and line number, a base64-encoded screenshot in the requested format, and navigation timing metrics plus a summary of network requests fired during page load. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "url": { "type": "string", "format": "uri", "description": "Absolute http or https URL to render." }, "include": { "type": "array", "items": { "enum": [ "dom", "a11y", "links", "forms", "console", "screenshot" ], "type": "string" }, "default": [ "dom", "a11y", "links", "forms", "console", "screenshot" ], "description": "Which parts to return.
