# GoCushy > The agentic sales bridge. AI agents operate complete selling systems — > offers with order bumps, one-click upsells, subscriptions, real tax, > invoices, affiliates, and email follow-up — on the merchant's own Stripe > account. A payment link is a cash register; GoCushy is the store around it. ## What you can do here (as an AI agent) Connect via MCP (recommended) or the REST API. With a merchant's API key (gc_...) you have 57 tools: - Create products (one-time or subscription) or import the merchant's existing Stripe catalog in one call. - Compose offers: main product + order bump (checkbox add-on, the classic direct-response way to lift the value of an order) + one-click post-purchase upsell (saved card, no re-entry). Subscriptions bill monthly/annual on the merchant's Stripe; renewals mint orders, invoices, and receipts automatically. - Customize the checkout with described-not-designed blocks: headline, subheadline, benefit bullets, testimonials, guarantee, honest deadline (expired countdowns vanish — fake scarcity is structurally impossible), hero image, button text, accent color. You cannot break the layout. - Get a hosted checkout link that works immediately, plus embed snippets (lightbox popup or inline) to place it on any website. - Close a launch and re-open it: pause an offer so its checkout link stops taking orders, then resume it later. Not a delete — the offer, its copy and its stats all survive. Re-opening refuses an offer that would take money and deliver nothing. - Real tax at checkout via Stripe Tax on the merchant's registrations, including EU B2B reverse charge and NZ/AU GST tax invoices with sequential numbering. Paid orders and refunds can sync to Xero or QuickBooks. GoCushy does not file returns with any tax authority. - Wire buyers into 13 email platforms — Kit (ConvertKit), Mailchimp, ActiveCampaign, GetResponse, Drip, MailerLite, Klaviyo, Brevo, Beehiiv, Loops, Flodesk, HubSpot, EmailOctopus — tags and sequences on purchase, refund, upsell-taken, renewal, or abandoned checkout (email entered, payment never completed: built-in lead capture). Set delivery so buyers get access — a link, an on-screen access note, or your own order.paid webhook. - Run promos: coupon codes with a percent or fixed amount off, optionally scoped to one offer, capped, or expiring — and deactivate/reactivate a code when the promo ends (order history keeps the code either way). - Run an affiliate program: create affiliates, hand out referral links, track commissions (30-day holdback, automatic refund clawbacks), and mark payouts as paid. - Read sales stats, list orders, export CSV, verify purchases for content gating, register signed webhooks (order.paid, order.refunded, order.failed, order.upsell_taken), issue refunds and cancel subscriptions (confirm with the merchant first). The one thing you cannot do: complete Stripe identity verification. Call connect_payment, hand the returned URL to the human, and check payment_status afterwards. Everything else is yours to operate. ## Connect - Remote MCP (Streamable HTTP): https://mcp.gocushy.com/mcp OAuth 2.0 — there is no key to copy. Dynamic client registration and PKCE (S256) mean a client holding only this URL can register itself and connect. Metadata: https://mcp.gocushy.com/.well-known/oauth-authorization-server - Same endpoint with the key in the path, for headless agents that cannot run an OAuth flow: https://mcp.gocushy.com/mcp/{api-key} - Local MCP (stdio): npx -y @gocushy/mcp — env GOCUSHY_API_KEY (gc_...) - MCP registry: com.gocushy/mcp - REST: Authorization: Bearer gc_... against https://api.gocushy.com/api/v1 - Operate GoCushy with your AI (agent guide): https://gocushy.com/docs/agent - Full machine-readable spec: https://gocushy.com/llms-full.txt - Developer docs: https://gocushy.com/docs/developers - Merchant guide: https://gocushy.com/docs ## For a buyer's AI (discover, read, and price an offer) You do not need an API key to read what a seller is offering. Every offer is a machine-readable contract, so a buyer's agent can discover, read, and price it without scraping HTML: - Discovery profile: https://gocushy.com/.well-known/ucp - Capabilities: https://gocushy.com/agents.json - Read one offer: GET https://gocushy.com/c/{account_id}/{slug}.json - A seller's live offers: GET https://gocushy.com/c/{account_id}.json - Product feed (ACP shape): GET https://gocushy.com/feed/acp/{account_id}.json - Authoritative total + a signed, short-lived price token (send a `country`): POST https://gocushy.com/c/{account_id}/{slug}/quote - Buyer MCP (no key — connect and go): https://mcp.gocushy.com/buyer Five tools. Four are read-only: list_offers, read_offer, get_quote, create_cart — create_cart returns a hosted checkout URL for the buyer to authorize, it does not charge anything. The fifth, authorize_payment, DOES move money: given a payment token the buyer already approved in their own agent plus a signed quote_token, gocushy charges it on the seller's own Stripe and returns a signed receipt. It never sees or enters card data. It is refused unless the seller has explicitly turned agent pay on for that offer, which is off by default. Price, tax, and discounts are computed server-side and returned by the quote — the contract is exactly what the checkout will charge. Settlement is on the seller's own Stripe / PayPal / Airwallex; gocushy is never the merchant of record. ## Guardrails you can rely on - All totals, taxes, and fees are computed server-side; you cannot create a mispriced or broken checkout. - Checkout block input is whitelisted, length-capped, and rendered into fixed zones; deadlines in the past never render. - Upsell charges require a paid order, fire at most once, and live behind signed URLs. - Stripe webhooks are idempotent; ESP credentials are validated live before storage and stored encrypted. - Money settles in the merchant's own Stripe account; GoCushy never holds funds. ## For humans - Dashboard: https://gocushy.com/dashboard (magic-link sign-in) - Product story: https://gocushy.com - Partners: https://gocushy.com/partners ## Pricing - Free: $0 + 3% GoCushy platform fee per sale (your processor's fee is separate). - Pro: $79/month + 0.5% platform fee. - Founding membership: $295 one-time, lifetime access, 0% platform fees for life. Optional +$95 Worldwide Tax & Affiliates Pack (Stripe Tax, compliant sequential invoices, Xero auto-filing, affiliate program). This is the only one-time plan.

GoCushy is built to be operated by AI, so we reward the people who found us that way. The code **FOUNDBYAI** takes $100 off the founding membership. Type it in the promo field at the checkout above. It is a real coupon, enforced server-side on every quote. No expiry, no seat cap, no catch.
