What ships today

The API, SDK, CLI and MCP pages describe the designed product, and each surface ships on its own. live works as the pages describe, beta runs with less or differently, and planned is documented and not shipped.

SurfacesCopy Anchor Link

What works on each surface now.

• API, beta. Sign in with npx startup-builder@0.3.0 login, then read records and preview Verbs through the CLI or the hosted MCP server.

  Copy Text

  curl https://api.sb/startups

• SDK, planned. The hosted MCP server’s do tool runs a different $, typed by https://api.sb/$.d.ts: only the Verbs it declares run there (see Verbs on api.sb), each call resolves to its Action (status Done, Pending, Refused, Failed or Canceled), not to the record this SDK returns, and a call without { mode: 'do' } runs in try and stores nothing.

  Copy Text

  claude mcp add --transport http sb https://api.sb/mcp

• CLI, beta. The do lines on these pages use 0.3.0’s own flags (--data, --do, --idempotency-key); the commands 0.3.0 lacks are marked on the CLI reference. Check a command’s flags with its --help.

  Copy Text

  npx startup-builder@0.3.0 login

• MCP, beta. Fetch https://api.sb/$.d.ts before a do program and call only what it declares. Preview in try, then pass { mode: 'do' }; run a write and a read of its result as two do calls.

  Copy Text

  claude mcp add --transport http sb https://api.sb/mcp

• Create, planned. Until it ships, describe the Startup on startups.new, or sign in with npx startup-builder@0.3.0 login and read it on api.sb. Open startups.new.

• Startup Interfaces, planned. A Startup’s records and Verbs are on api.sb, at its namespace, for the Verbs api.sb declares.

  Copy Text

  curl https://api.sb/startups

• SOC 2, planned. Share the Control and framework map pages; a buyer who needs an audited report asks the Startups.Studio team on startups.studio. Open startupbuilder.dev/systems/trust-and-governance/frameworks.

• Docs MCP, live.

  Copy Text

  claude mcp add --transport http startupbuilder-docs https://startupbuilder.dev/mcp

• startups.new, beta. Open startups.new.

Works todayCopy Anchor Link

Works today. These lines run against api.sb now. The outputs shown were captured from it; the CLI and MCP lines follow the startup-builder 0.3.0 README.

1. Read the Studio’s Startups, with no sign-in:

   Copy Text

   curl -s "https://api.sb/startups?limit=1" | jq '.startups[0] | {"$id", name, status}'

   Copy Text

   {
     "$id": "https://api.sb/adjusters.directory",
     "name": "adjusters.directory",
     "status": "Designed"
   }

2. Read what the hosted $ declares: curl -s 'https://api.sb/$.d.ts' returns the index of 73 Nouns and their Verbs. What ships today lists them.

3. Sign in: npx startup-builder@0.3.0 login opens id.org.ai in your browser (login --device in a terminal with none), and npx startup-builder@0.3.0 whoami prints who api.sb sees.

4. Read a Startup: npx startup-builder@0.3.0 show /headless.ly --json.

5. Preview a Verb: npx startup-builder@0.3.0 do <Noun.verb> <$id> --data '<json>' runs it in try and stores nothing; add --do to run it. npx startup-builder@0.3.0 help do lists every flag.

6. Connect an agent: claude mcp add --transport http sb https://api.sb/mcp, sign in from /mcp, then call do with return await $.search('headless.ly'). A call runs in try unless it passes { mode: 'do' }, and resolves to its Action.

Verbs on api.sbCopy Anchor Link

api.sb serves 164 of the 1109 Verbs these pages document. Each Noun below also reads with get, list, find. A Verb outside this table is planned on every surface: its page says so, /verbs.json gives it "apiSb": false, and a guide that calls it is planned.

Package entry pointsCopy Anchor Link

Each path a page imports or runs, and what resolves at it on npm.

The worked exampleCopy Anchor Link

Leaseline is the worked example. leaseline.app and api.leaseline.app do not resolve and api.sb/leaseline.app returns 404, so its ids show the shape of a record, and a copied call returns 404 today.

Every example keeps its Leaseline ids, labelled as the worked example, so pages agree with each other and with the types this site hosts.
