78/100

APIstax (apistax.io) received an AI-readiness score of 78/100 in an automated technical audit. llms.txt was accessible, llms-full.txt was not found, and ai.txt was not found. The robots.txt analysis found 0 explicitly allowed and 0 blocked AI crawlers, with 0 declared sitemaps. Homepage markup completeness was 90%; Schema.org types included Product, SoftwareApplication, Review, FAQPage and 8 OpenGraph tags were detected. Results reflect the public site response observed on 2026-08-10T00:05:09.284Z.

Audit context

llms.txt is accessible and contains 1,176 tokens. No accessible llms-full.txt was detected, so deeper context still has to be assembled from regular pages. No separate ai.txt policy was detected; it is optional, but can clarify training, retrieval, and attribution preferences.

robots.txt is available. 11 of 11 tracked AI bots are not blocked. Declared sitemaps: 0. The homepage exposes Schema.org types Product, SoftwareApplication, Review, FAQPage; 8 OpenGraph tags were found and markup completeness is 90%.

The mobile Lighthouse profile adds Performance 94/100, Accessibility 97/100, Best Practices 100/100, SEO 100/100, and experimental Agentic Browsing 100/100. These signals have a limited weight: they complement rather than replace llms.txt, robots.txt, and structured-data checks.

What these results mean

The mobile page renders efficiently; its largest visible content block appeared in 2.5 s.

Accessibility scored 97/100, Best Practices 100/100, and technical SEO 100/100. The experimental Agentic Browsing category scored 100/100. It measures signals Google currently tests for software agents and is shown separately from the llmsmap AI-readiness score.

Free the main thread and accelerate the first view

Split long JavaScript tasks, defer non-critical scripts and styles, and shorten blocking request chains. This helps the primary content appear sooner and makes controls usable earlier.

Reduce code that loads without helping the page

Remove unused CSS and JavaScript, load heavy widgets on demand, and limit third-party scripts. Less code means less parsing and background work on the device.

Optimise images and their loading order

Serve correctly sized modern formats, prioritise the primary visual, and lazy-load content below the first viewport.

Reduce network delay

Improve server response time, remove unnecessary redirects and repeat downloads, and use compression, caching, and selective preconnect hints.
