Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-h2-term?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, cheap literal keyword matching specifically within H2-level headings of a static HTML page — ideal for SEO audits, content structure checks, documentation discovery, or heading presence verification. Prefer this over full-page scrapers when you only care about H2 elements and want a bounded, structured result at minimal cost ($0.01 USDC). Not suitable when H2 content requires JavaScript rendering, login, or when fuzzy/semantic matching is needed.
