POST
Reference example
Search the web and get back ranked results. query is required; limit sets how many. Returns success, creditsUsed, a request id, and data.web[] with url, title, description and position — titles and snippets only, no page text. Measured at about 15 seconds for 2 results, the slowest of the search tools here. Billed per Firecrawl credit, roughly ceil(limit / 10) * 2. On the AIsa metered profile only the web source is supported; scrapeOptions, enterprise mode and non-web sources are rejected. Reach for something else when: you want the page text in the same call — post_tavily_search returns it and answers in a third of the time; you already know the URLs — post_firecrawl_scrape; you want relevance judged by meaning rather than keywords — post_exa_search.
First time? Point any MCP client at https://mcp.aisa.one/mcp — Claude Code, Codex, Cursor, VS Code and the rest. Authorization is OAuth: the client opens a browser, you click Allow once, and there is no key to paste. Your agent then reaches every endpoint through a few meta tools: search, list_categories, get_details and batch_quote are free, batch_use is billed per call. Setup per client is in Connect via MCP; the live tool list and what each call costs are on aisa.one/mcp.
