GET
List of Google Languages for SERP API
Returns the full list of languages supported by the Google SERP API, so you can resolve the language_code used when posting SERP tasks. Each entry carries language_name and language_code (ISO 639-1). 💰 Upstream is free — DataForSEO does not charge for this dictionary; AIsa bills the flat $0.012 family rate. 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.
