What you get. Five products and four bonuses.

One API for plans, access and offers. Your app asks what an account can do and gets one answer.

• One call for access. The full plan merges the account's plan, offer extras and incentive into one list of features and limits.
• Usage metering. Count credits, seats and storage against each limit. At the limit, the API answers 402 with an upgrade and a checkout link.
• Signed webhooks. Plan changes, limit warnings and cancel saves, signed to the Standard Webhooks spec and retried when delivery fails.
• Keys for each side. A publishable key for the browser, a secret key for your server and short-lived account tokens for cancel flows.
• React SDK. Hooks and gates for access checks, plus headless checkout and cancel flow components you style like your app.
• OpenAPI spec. Browse every endpoint at /docs or generate a client from /openapi.json.

A dashboard for everything you sell. Change a plan or a limit and the next API call has it. No deploy.

• Catalog. Plans, entitlements, add-ons and incentives, each with its own record page.
• Accounts. Look up any customer's plan, usage and incentive, and change them by hand.
• Offers. Build an offer against a live checkout preview, then share its link with a ref for each partner.
• Analytics. Usage per feature, accounts by plan and your heaviest users over time.
• Agent. Ask about accounts and usage in plain English, or have it draft plans and incentives. Nothing changes until you approve.
• Workspaces. Invite your team, and keep each app's keys, webhooks and PayPal connection apart.

Your offers and entitlements in any agent. Connect any AI assistant or coding agent to your app.

• Every endpoint is a tool. Accounts, plans, entitlements, incentives, usage and webhooks, with the same parameters as the API.
• Access per connection. Read only, read and write, or full access. Clients ask before they run anything that deletes.
• OAuth or a key. Sign in with OAuth from chat apps, or use a secret key in coding agents.
• Prompts included. Review your catalog, investigate an account, launch an incentive or debug a webhook in one step.
• Resources. Your catalog, pricing cards and recent events, ready to read as context.
• Activity log. See which client called which tool, with its arguments and result.

Sell any offer through PayPal. Each link carries its own prices, bumps and extra entitlements.

• One page for every offer. Build your checkout once from SDK components, then pass a different offer for each ad, partner or promo.
• Monthly, yearly or once. Each plan in an offer gets its own price per interval, plus order bumps charged with the first payment.
• Prices checked on the server. Every selection is priced again before it reaches PayPal.
• Access on payment. PayPal's webhook moves the account to its plan and grants the offer's extra entitlements.
• Offers that change. Edit an offer's prices or extras and the live link follows. Set an end date and it stops selling.
• Partner credit. Add a ref to any link and each sale is credited to that partner.

A cancel flow that makes the save offer. An agent picks one for each customer, and PayPal takes the approval.

• Your questions. Set the reasons and steps in the dashboard. Your app code doesn't change.
• Agentic save offers. The agent reads the account's usage and reason, then picks a discount, pause, downgrade or incentive.
• Guardrails on the server. You cap what it can offer, and the API checks every pick against your caps.
• Approved in PayPal. Discounts and downgrades open PayPal for the customer to approve. Nothing changes without it.
• Pauses that end on time. A Render Workflow suspends the subscription and resumes it on the date you set.
• Save rate per reason. See why customers leave, which offers they take and how much monthly revenue you kept.
