Web search through your Google Programmable Search Engine (Custom Search JSON API). Returns query, total_results (Google's estimate — it can shrink while paging), search_time_seconds, corrected_query (spelling suggestion; results are still for the original query), next_start/previous_start page cursors, and items[] with title, url, display_link, snippet, mime/file_format and (with include_pagemap) pagemap metadata. Coverage is the engine's configuration: an engine listing specific sites searches only those; open-web search needs "Search the entire web" enabled in its control panel — results still differ from google.com. Max 10 results per call and 100 per query: paginate by passing next_start as start. Each call costs one unit of the daily quota (free tier 100/day), so prefer one precise query over many broad ones. Note: this is Programmable Search, NOT Google Search Console — it cannot report how your own site is indexed or ranked.

Image search through your Google Programmable Search Engine (searchType=image). Works only when the engine has "Image search" enabled in its control panel — otherwise the API answers 400. Each item's url is the image file itself; image.context_url is the page hosting it, with width/height/byte_size and a thumbnail_url (plus its dimensions) for previews. Everything else matches the search tool: same filters (language/country, safe search, site include/exclude, date_restrict, file_type, rights — use rights for reusable images), same pagination (max 10 per call, 100 per query, paginate via next_start), same quota (one unit per call). Image-only filters: size (icon..huge), type (clipart/face/lineart/stock/photo/animated), color_type (mono/gray/color/trans) and dominant_color.

Escape hatch: performs a GET against any Custom Search JSON API path and returns the raw, unnormalized response envelope (queries.request/nextPage, searchInformation, promotions, context, items[] with htmlSnippet/htmlTitle/formattedUrl and the full pagemap). Use it for parameters the typed tools don't expose (lowRange/highRange, c2coff, hq, fields) — e.g. path "customsearch/v1?q=test&num=3&fields=items(title,link)". The API key is added automatically (in a header, never the URL) and the configured engine id is filled in when the path has no cx parameter. The API has GET endpoints only, so nothing here can modify data.
