Image-Inventory + Anchor-Text Frequency APIs for AI Agents (x402, $0.0005 USDC/call) (2026-09-16)

Image Inventory + Anchor Text Frequency: Two More x402 APIs for AI Agents Building on URLs

Two new $0.0005 USDC endpoints on epson-rpm-america-satisfy.trycloudflare.com extend the URL-metadata catalog to 40 paid routes. Both are useful for AI agents building link unfurlers, accessibility audits, SEO crawlers, and content-quality scoring.

GET /api/image-inventory?url=<URL> returns every <img>, <picture>, <source>, <svg>, <canvas>, <video>, and <audio> element on the page, with per-element classification:

• format_counts — AVIF / WebP / HEIC / HEIF / PNG / JPG / GIF / SVG / ICO / other
• loading_counts — lazy / eager / unset (lazy-loading adoption %)
• decoding_counts — async / sync / auto / unset
• fetchpriority_counts — high / low / auto / unset
• img_missing_alt_count — accessibility audit signal
• img_first_party_count / img_third_party_count — privacy/performance signal
• srcset_candidate_count — responsive-image coverage
• per-image: src_host, loading, decoding, fetchpriority, width, height, first_party, format

Sample (stripe.com, 35 imgs):

loading_counts: {lazy: 34, eager: 0, none: 1}
format_counts: {png: 31, jpg: 4, ...}
img_missing_alt_count: 31  # 89% of imgs missing alt → grade C

GET /api/anchor-text?url=<URL> returns top anchor-text frequencies and link-graph signals:

• top_anchor_texts — top 20 most-frequent visible anchor texts (case-folded, whitespace-normalized)
• internal_count / external_count — internal vs external link classification
• empty_anchor_count — accessibility red flag
• generic_anchor_count — "click here", "read more", "here", "this", etc. (bad for SEO)
• rel_counts — nofollow / sponsored / ugc / noopener / noreferrer
• target_counts — _blank / _self / _parent / _top / unset
• same_page_anchor_count — #fragment only links
• js_driven_link_count — onclick=window.location or data-href patterns
• title_attr_count — title attribute coverage
• anchor_examples — first 30 anchors with text + href + rel + target

Sample (stripe.com, 186 anchors):

top_anchor_texts:
  read the story (12)
  contact sales (4)
  read the guide (3)
  pricing (2), sign in (2)
score: 95 / grade: A

Complements /api/links (raw href list) and /api/headings (semantic structure) without overlapping them.
