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.
