GET/v1/serp-read$0.088Web search plus page reading in one call: answer with sources. Runs a web search, scrapes the top results, and returns the ranked search results together with each page's content as clean LLM-ready markdown, so an agent gets the SERP AND the underlying text without a second round of scrape calls. Per-page fetch errors are reported honestly per URL.

Solves the broad-term entry problem dense semantic search fails on. Keyless.
GET/v1/time$0.01Current time, date, and timezone data for AI agents: the clock an LLM does not have.
