# One API for Agents

> One API for Agents is a connection broker and data layer for AI agents. A workspace holds connected accounts (Google Search Console and Google Analytics 4 today), and agents reach them through one REST API (https://api.oneapiforagents.com/v1) and one OAuth-enabled remote MCP server (https://mcp.oneapiforagents.com/mcp). Every call is logged with request, response, latency and cost.

Key facts:

- Dashboard: https://app.oneapiforagents.com (sign in with Google or an email magic link).
- REST: `POST https://api.oneapiforagents.com/v1/call` with `Authorization: Bearer oa_…` and a body such as `{"provider":"gsc","endpoint":"sites.list"}` or `{"provider":"gsc","tool":"gsc_top_queries","input":{"siteUrl":"sc-domain:example.com"}}`.
- MCP: `https://mcp.oneapiforagents.com/mcp`, streamable HTTP, OAuth 2.1 with PKCE and dynamic client registration.
- Agencies send connect links so clients connect their own Google accounts, read-only, with no password sharing.
- It is a wrapper: no background syncing and no website monitoring.
