[Services & Deliverables]

Agentic infrastructure services built for autonomous models.

Visual websites were built for human eyes. stacktxt builds the machine-readable data infrastructure required for autonomous AI assistants, shopping agents, and conversational search engines to crawl, index, and purchase from your digital storefront without hallucination.

[Stage 01 · Diagnostic & Reading Layer]

Starter Tier

Foundational machine legibility and crawl health.

We crawl your storefront exactly as AI models do, measuring crawler permissions, schema health, and token bloat. We deploy the baseline /llms.txt reading layer and ARD discovery manifest so conversational assistants understand your core catalog.

[Included Technical Deliverables]

Google Lighthouse & Core Web Vitals Audit

Headless crawl measuring LCP, CLS, INP, mobile rendering latency, and AI bot crawlability constraints.

Proprietary ARD Manifest Deployment

Configuration of the Agentic Resource Discovery manifest at /.well-known/ard.json (Schema v0.91) and insertion into robots.txt.

Machine Reading Layer (/llms.txt)

Root semantic Markdown manifest stripping bloated layout and scripts, reducing model token consumption by 90% to 95%.

AI Crawler Allow Directives

Custom robots.txt configuration explicitly permitting conversational discovery crawlers (OAI-SearchBot, PerplexityBot, Claude-SearchBot, Applebot-Extended).

WebMCP & UCP Declarative Readiness Check

Baseline probe of /.well-known/webmcp.json and form annotations for in-browser agent tool calling.

Monthly Crawler Policy & Drift Reporting

Automated 30-day monitoring digest auditing AI crawler access and catalog legibility.

[Stage 02 · Deep Catalog & Shopping Graph]

Growth Tier

Deep catalog synchronization, structured schemas, and shopping graphs.

Everything in Starter plus full catalog feed normalization, high-density /llms-full.txt compilation, verified Schema.org JSON-LD nodes, and weekly catalog synchronization so shopping agents recommend your products with 100% pricing accuracy.
