Web & SEO data API — FAQ
Do I need a Web & SEO API key or developer account?+
No. Sourcelane runs the connectors for you. You top up a balance with a card, create an agent key, and your agent calls the connector — there is no Web & SEO app review, OAuth setup or rate-limit juggling on your side.
Which AI tools can use it?+
Anything that speaks MCP (Claude Desktop, Claude Code, Cursor, VS Code, Windsurf) can connect to the Sourcelane MCP server with one config block. ChatGPT can use it through a Custom GPT Action, and any agent framework can call the REST endpoint directly.
Can I stop an agent from overspending?+
Yes. Every agent key has its own per-call cap, daily and monthly limits, an optional lifetime budget, an allowlist of connectors, and a kill switch.
