This is the shortest path from a new buyer account to a campaign you could launch. Each step can be done in the app with Semi, in an MCP host, or through the API.
1

Sign in and pick the buyer account

Sign in at app.semicola.com. If you belong to several accounts, use the account selector in the top bar. Semi’s home greets the active account, for example “Let’s drive revenue for Wrenfield Coffee Co.”
2

Accept terms and choose a plan

An organization admin accepts the terms and picks an IU plan under Settings → Plan & billing. Until then, launches are limited to sandbox. See How IU billing works.
3

Add an advertiser

Say “add an advertiser” or call open_add_advertiser. Enter the brand domain; Semicola looks up the brand card. Confirm the primary currency, markets and channels. Start with sandbox on while you learn. See Advertiser.
4

Choose your sellers

“Show me where I can advertise” opens the Sellers page. Include the sellers you want briefs to reach, and finish any account mapping a seller asks for. See Connections.
5

Brief a campaign

Describe the campaign in a sentence or two. Semi confirms the budget and currency, creates a draft and asks sellers for proposals. See Product discovery.
6

Add creatives and review

Build or upload creatives, attach them, then open Review & go live to see the plan, staged buys, format coverage and any blockers.

What get_status says along the way

get_status reports readiness for the active account, with a blocker for each unfinished step and a next action that usually names the tool to call. Agents should read it at the start of a session and after every setup change.
Invite teammates under Settings → Members. Admins manage billing and members; operators and members can plan and run campaigns.
