Reference example
List a site’s URLs from a root url without fetching any page content. Steer it with natural-language instructions and regex select_paths / exclude_paths / select_domains filters. Returns base_url and results — a flat array of URL strings, not objects — with response_time and request_id. Fast and cheap: measured at about 1.5 seconds. Use it to size a site before committing to a crawl, then fetch only the parts that matter with post_tavily_extract. When you want the content rather than the shape, post_tavily_crawl does both in one call.
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 five tools: search, list_categories and get_details are free, use and batch_use are 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.

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): 0.064
  • Declared unit rate (USD): 0.008
  • Billing unit: tavily_credit
  • Cost contract: response_units
  • Published reference multiplier: 1.0
  • Settlement evidence source: response_body
