Pricing

Simple, usage-based pricing

Browse pricing before you create an account. Subscribe to activate the developer portal, then pay only for successful API, MCP, and tool calls — you set what to charge your own clients.

Platform access

$4.00/ month

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

Includes 133 API credits each billing period (on subscribe and every renewal).

  • Developer dashboard & company provisioning
  • REST APIs, MCP tools, and employee portal endpoints
  • US & Canadian payroll compliance engine
  • Public API docs — no account required

API usage

$0.03/ credit

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

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 $4.00/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. Resell payroll to your clients at whatever PEPM or per-run pricing you choose — we do not take a cut.
