Lemon Squeezy API
SaaS billing and digital product payment platform acting as a Merchant of Record (MoR). Lemon Squeezy handles global tax compliance, VAT/GST collection, and payment processing — creators and indie SaaS developers don't need to set up Stripe Tax or handle international tax obligations. Simpler than Stripe for solo developers and small teams selling digital products or SaaS subscriptions.

⚡ Reliability
Best When
You're an indie developer or small SaaS team that wants simple, tax-compliant global billing without becoming a tax expert or managing Stripe Tax configuration.
Avoid When
You need complex pricing logic, high-volume transaction processing, or enterprise B2B billing features — Stripe or Chargebee provide more control.
Use Cases
- • Sell agent-powered SaaS products with automatic global tax handling without implementing Stripe Tax or VAT compliance
- • Create subscription billing for AI tools via Lemon Squeezy's checkout and subscription management API
- • Process digital product sales (templates, datasets, models) with automated license key generation and delivery
- • Build license validation for AI tools using Lemon Squeezy's license key API for agent-gated feature access
- • Implement usage-based billing metering via Lemon Squeezy's subscription management API for API-billed agent services
Not For
- • High-volume enterprise billing requiring complex pricing models — Stripe Billing or Chargebee have more flexibility
- • Physical product or marketplace selling — Lemon Squeezy is for digital products and SaaS
- • B2B enterprise sales with purchase orders and invoicing workflows — Paddle or Stripe are more enterprise-capable
Interface
Authentication
API key passed in Authorization Bearer header. Keys generated in Lemon Squeezy account settings. Single key with full API access — no scope granularity.
Pricing
Revenue share model (% per transaction) rather than flat monthly fee. Payment processing (Stripe) adds 2.9% + $0.30. Plus plan reduces Lemon Squeezy's cut. MoR model means Lemon Squeezy handles tax compliance.
Agent Metadata
Known Gotchas
- ⚠ As Merchant of Record, Lemon Squeezy's refund and dispute policies apply — agents building agent services must understand MoR implications
- ⚠ Webhook signature validation is required — use the provided HMAC signature to validate webhook authenticity before processing
- ⚠ License key validation API is separate from the main API — agents implementing license gating must use the specific license validation endpoint
- ⚠ Checkout URLs expire and are single-use — agents must create new checkout URLs for each purchase attempt
- ⚠ Currency handling: Lemon Squeezy converts to buyer's local currency automatically — pricing in USD is converted at checkout
