POST
Search Web Content
Search the open web and get back a lean result list. ⚠️ Despite being a POST, parameters go in the query string — query (required), max_num_results (default 10, max 100), and as_ylo/as_yhi for a year range. A JSON body is not accepted. Returns a search id and results[] carrying only title, link and snippet. Measured at about 4 seconds for a roughly 600-byte response. Its virtue is how little it returns, which suits an agent that only needs to know what exists. It gives you no page text — if you need the content, post_tavily_search returns it in the same call. Keep the id: it is what post_scholar_search_explain needs.
Scholar search endpoints use POST with parameters in the query string. Do not send query or max_num_results as a JSON or form body.

Example

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. The commands per client, and what each call costs, are on aisa.one/mcp.

Cost and request rules

Published reference values are not an account-specific quote or a settled charge. For endpoints supporting X-AISA-Cost-Mode: quote, obtain a free quote for your exact request before execution; reconcile the settled cost with response metadata and Usage Logs. USD amounts use 1,000,000 integer micro-USD per dollar.
  • Default request reference estimate (USD): 0.01
  • Cost contract: fixed_success
  • Published reference multiplier: 1.0
  • Settlement evidence source: request_snapshot
