ツール（18）

🟢 読み取り専用🟡 書き込み🔴 削除⚪ 不明
🟡search(query, max_results, extract, include_content, content_results, ...)

Real-time web search and content retrieval - up to 10 results with title, URL, snippet and publish date, plus clean full-page Markdown for the top 3 results by default and an optional short summary. Also accepts up to 5 queries in one call, merged and de-duplicated - one call instead of five. No account, no API key, no quota. Try GET /search/sample. Part of the AgentIndex content kit (pdf, web-read, extract, summarize, detect-language) - see GET /capabilities.

🟢translate(text, target_lang, source_lang, preserve_format)

Translate up to 200 text segments in a single call - the same result that would otherwise take 200 separate calls to translate a whole file. Markdown, HTML and {x} placeholders preserved per segment, order and count kept intact, source language auto-detected, automatic fallback across multiple models for uptime, providers that train on submitted prompts excluded. A single string also works. No account, no API key. Try GET /translate/sample.

🟢jobs(subject)

Multi-query web research, read and synthesized into one sourced JSON brief in a single call - what would otherwise cost an agent twenty calls and its whole context window. Free status polling and result retrieval. Try GET /jobs/sample.

Text content itself is never generated or altered, only its structure is inferred. Try GET /pdf/sample.
