About Manifest

Manifest by Omfang is a web-action API for AI agents: point it at any URL and it returns a clean JSON map of everything an agent can click, fill, and submit on that page, including the fields each action needs and what's required before it can proceed. Under the hood, Manifest visits the URL, reads the page's accessibility tree the way a screen reader would, and cross-references it against the live DOM for details accessibility trees miss — required flags, input types, placeholders, and disabled states. The result is a structured action manifest that survives redesigns and removes the need for hand-written selectors or screenshot-guessing. Developers call POST /manifest with a URL and get back the page state, an actions array (buttons, inputs, forms with descriptions), and navigation links — a stable action layer their agent can reason about and execute against.

Key Features

URL-to-Action Manifest: A single POST call turns any page into a JSON manifest of buttons, forms, and inputs with descriptions and required flags.
Accessibility-Tree Grounding: Reads the page the way a screen reader does, so labels and roles come from semantic signals instead of guessed CSS.
DOM Cross-Referencing: Augments the accessibility tree with input types, required fields, placeholders, and disabled states pulled from the live DOM.
Redesign-Resilient Selectors: No hand-maintained CSS paths — Manifest re-derives the action set per request so page redesigns don't break your agent.
Structured Navigation Extraction: Returns the page's navigation links alongside actions so agents can plan multi-step flows across a site.
Developer-First API: Simple REST endpoint, live playground, and docs designed for teams building browser-using AI agents.

Use Cases

Agent Web Task Execution: Give an autonomous agent a machine-readable list of what it can actually do on any given URL before it acts.
Automation Without Brittle Scrapers: Replace hand-written selectors with a resilient action layer that survives page redesigns.
Form-Filling and Sign-Up Automation: Let agents discover required fields, input types, and validation constraints before submitting a form.
Multi-Site Workflow Orchestration: Compose flows that span vendor portals, SaaS dashboards, and public sites using a consistent action schema.
QA and UI Auditing: Snapshot a page's interactive surface as structured data to compare across releases or audit accessibility gaps.

How does Manifest work?

Manifest works by creating a JSON manifest of actions from any webpage, utilizing techniques like Accessibility-Tree Grounding and DOM Cross-Referencing. This allows autonomous agents to effectively interact with web elements, automating tasks like form-filling and navigation without relying on fragile selectors.

Key Points

  • URL-to-Action Manifest: Transforms web pages into machine-readable action lists.
  • Accessibility-Tree Grounding: Ensures accurate interpretation of webpage elements for screen readers.
  • Redesign-Resilient Selectors: Adapts to page changes without breaking functionality.

Detailed Explanation

Manifest employs several innovative techniques to enhance web automation:

  1. URL-to-Action Manifest: By making a single POST call, Manifest generates a comprehensive JSON object that describes available buttons, forms, and inputs on a webpage. This object includes essential attributes like required flags, which inform the agent about which fields must be completed.

  2. Accessibility-Tree Grounding: This feature reads and interprets the webpage in a manner consistent with screen readers, ensuring that labels and roles are derived from semantic HTML elements rather than relying on potentially inaccurate CSS selectors. This approach enhances both accessibility and automation reliability.

  3. DOM Cross-Referencing: Manifest augments the accessibility tree by pulling live data from the DOM. This includes input types (such as text boxes and dropdowns), required fields, placeholders, and disabled states. This real-time data ensures that agents can accurately interact with the webpage.

  4. Redesign-Resilient Selectors: Unlike traditional methods that depend on fixed CSS paths, Manifest re-derives actions dynamically for each request. This adaptability means that even if a webpage undergoes significant redesigns, the automation will continue to function seamlessly.
