Reference example
Returns datasets matching a query in Google Dataset Search on Google, synchronously. Returns keyword, type, se_domain, location_code, language_code, check_url, datetime, spell, refinement_chips, item_types, items_count and items. Measured at 57 KB for a ten-result Google query. ⚠️ Three result depths exist for the same query and differ by two orders of magnitude: regular measured 4.8 KB, advanced 57 KB, and html 2.4 MB. advanced is the default choice; take regular when only the ranked list matters and html only to check what the parser dropped. Wrapped in DataForSEO’s envelope: data in tasks[0].result, outcome in tasks[0].status_code - a rejected request still returns HTTP 200.

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): 0.02
  • Cost contract: response_usd
  • Published reference multiplier: 1.0
  • Settlement evidence source: response_body
