What you can sell
One platform for every kind of software sale
Repos, subscriptions, APIs, downloads, license keys, and community access — all sold in USDC with access delivered automatically.
SaaS plans
Create plans, sell subscriptions, manage seats, and check entitlements with the SDK — no billing to build.
Paid APIs
Wrap an endpoint with x402 middleware and charge humans and agents per call in USDC.
AI agent services
Make your service discoverable and payable by autonomous agents over Circle Gateway and x402.
Digital downloads
Sell ZIPs, datasets, and assets with signed, expiring download links delivered on payment.
License keys
Issue and verify license or API keys automatically at checkout, with revocation on refund or expiry.
Discord communities
Sell paid access to a community — buyers get a Discord role on payment and lose it on expiry.
How it works
Create product → Set price → Buyer pays → Access delivered
From an idea to delivered access in four steps. SettleKit verifies the USDC payment and grants every deliverable automatically.
- 1
Create product
Pick what you're selling — repo, plan, API, download, license, or Discord access.
- 2
Set price
Choose a one-time or recurring USDC price. Bundles can combine several deliverables.
- 3
Buyer pays
Share a checkout link. SettleKit verifies the USDC payment on settlement.
- 4
Access delivered
Repo access, license keys, downloads, and Discord roles are granted automatically.
Developer tools
Built for developers, not just checkout
SettleKit ships the primitives you'd otherwise build yourself: SDKs, webhooks, entitlement checks, and pay-per-call API middleware.
SDKs
Typed client and server SDKs to check entitlements, list products, and gate features in your app.
Webhooks
Signed events for payments, subscriptions, deliveries, and refunds — with replay for reliability.
Entitlements
Ask one question — does this customer have access? — and gate repos, features, and downloads.
x402 middleware
Drop-in middleware that turns any HTTP endpoint into a pay-per-call API for humans and agents.
