Feature & Specification Comparison
Tools & Capabilities Breakdown
Onto Tools (6)
read_url
Returns clean Markdown for a URL with metadata about the extraction (sizes, reduction %, cache state).
score_url
Returns the AIO (AI-readability) score for a URL — 0-100 with a letter grade, hallucination risk, and a structured list of penalties / benefits / recommendations.
read_and_score
Returns clean Markdown plus the AIO score in one call. Recommended default for agentic workflows.
batch
Process many URLs in **one call**. **N credits** — one per URL in the list after the list is known. Failed URLs (`ok: false`) are refunded. Default mode `read-and-score` is still N, not 2N. Give an explicit list or a base URL whose pages are auto-discovered.
map_site
Discover a site's URLs (sitemap → on-page links) without reading them. **1 credit per call** (not per discovered URL) — use it to plan which pages to read or batch next.
