POST
Reference example
Word and phrase frequency across a crawl, with keyword_length choosing n-gram size. Returns total_items_count, items_count and items. Measured at 611 bytes. Reads a finished crawl, so it needs the id from post_dataforseo_on_page_submit and returns crawl_progress plus a crawl_status of max_crawl_pages, pages_in_queue and pages_crawled - check those before trusting a small result, because a crawl still running simply has less to report. This describes what a site says about itself; for what the web says about it use post_dataforseo_backlinks_anchors_live, and for what people search use post_dataforseo_keywords_gads_search_volume_live. ## 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): 0.012
  • Cost contract: response_usd
  • Published reference multiplier: 1.0
  • Settlement evidence source: response_body
