Platform access

$49.00/ month

Keeps your developer account active and unlocks company provisioning, API keys, MCP connections, and the billing portal.

Includes 1633 API credits each billing period (on subscribe and every renewal).

  • Developer dashboard & company provisioning
  • REST APIs, MCP tools, and employee portal endpoints
  • White-label branding, domains, and multi-tenant companies
  • US & Canadian payroll compliance engine
  • Public API docs — no account required

API usage

Each successful REST request, MCP tool call, or agentic tool execution uses one credit. Failed calls, validation errors, and employee portal logins are not metered.

  • apay_ and dkey_ authenticated requests
  • MCP invocations from Claude, Cursor, and other clients
  • Agentic tools via POST /api/agentic/tools/execute
  • Top up anytime after subscribing

Browse API documentation without signing in.

How billing works

  1. Create a developer account — free to register; subscribe when you are ready to provision companies and call APIs.
  2. Subscribe at $49.00/month. Included monthly credits are added automatically.
  3. Use credits as you integrate. When your balance runs low, buy more from the billing page.
  4. White-label under your brand and resell payroll to your clients at whatever PEPM or per-run pricing you choose — we do not take a cut. For a branded launch, email [email protected].
