Credits & Subscription - SMB Sales Boost API
Starter, Growth, and Scale plans use a credit-based system where each lead queried or exported costs 1 credit. Unused credits roll over each billing cycle and never expire while your subscription is active. Use these endpoints to purchase additional credits or manage your subscription.
Credit balance: Your current credit balance is always available via GET /api/v1/me - see the monthlyCredits, monthlyCreditsRemaining, permanentCredits, and totalCreditsRemaining fields.
Endpoints
POST /api/v1/purchase-credits- Purchase additional credits using your saved payment method (charged off-session via Stripe). Purchased credits roll over month to month and never expire while your subscription is active. Minimum 100 credits. Pricing: Starter 10¢/credit, Growth 7.5¢/credit, Scale 5¢/credit. Only available for Starter, Growth, and Scale plans.
POST /api/v1/subscription/cancel- Cancel your subscription at the end of the current billing period. Your access continues until the period ends. Any remaining credit balance is forfeited when the subscription ends.
