GET
Referring Domains
Referring domains linking to a target, aggregated by domain. Billing is per returned data row (up to 20 rows). Current prices are on aisa.one/api. A broad seed returns more rows, so the input size decides the cost — start narrow. ⚠️ The response is semicolon-delimited text, not JSON — parse it as CSV-style rows. Related: get_semrush-backlinks, get_semrush-backlink-competitors.
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.
