From sign-up to first call in six steps.
No sales call, no approval queue on your side. You can be reading real marketplace data the same day.
Sign up and get a test key
Create a workspace and start on the Free plan. Your key arrives straight away, so you can look around before you connect anything.
Connect an account
Authorize a seller or vendor account through a hosted connect flow. History is already there once it is connected, up to 90 days on Free.
Call the API
Every call is a POST to /public/v1/tools/{tool_name} with a JSON body and your key in the X-API-Key header. Prefer an agent? The MCP server exposes the same tools.
curl -X POST https://api.sellermate.ai/public/v1/tools/get_campaign_performance \
-H "X-API-Key: sm_live_..." \
-d '{"start_date":"2026-10-01","end_date":"2026-10-25"}'Make changes safely
Create and change campaigns, ad groups, targets and bids. Production writes need a real connected account, with budget caps, preview before apply, idempotency keys and an audit log of every write.
Get notified
Subscribe a webhook and we tell you when something changes, so you do not have to poll.
Grow without a sales call
Connecting a second account moves you to Build. A fourth moves you to Scale. You always see the account count and the bill before it is charged.
