What Lemon Squeezy Catalog (BYOK) is for

Lemon Squeezy Catalog (BYOK) lets an AI assistant read your own Lemon Squeezy Catalog data through the Lemon Squeezy Catalog API with a key you supply (API key). Read-only: 7 tools (list_variants, list_prices, list_discounts, list_discount_redemptions, list_order_items, list_subscription_items, list_files). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.lemonsqueezy.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Lemon Squeezy Catalog. Lemon Squeezy Catalog and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "What variants and prices does product 19 have on Lemon Squeezy?"
• "What are the pricing tiers of Lemon Squeezy variant 11?"
• "Which discount codes are live on my Lemon Squeezy store?"
• "How often has discount 1 been redeemed on Lemon Squeezy?"
• "Which Lemon Squeezy variants sold the most items?"
• "Which Lemon Squeezy subscription items are on price 1?"

What it does

• list_variants: List product variants with name, price in cents, subscription interval, trial settings, license key settings and status, optionally for one product or status.
• list_prices: List prices with category, scheme, unit price in cents, tiers, renewal interval, trial, setup fee and tax code, optionally for one variant.
• list_discounts: List discount codes with name, code, amount and type, redemption limits, start and expiry, duration and status, optionally for one store.
• list_discount_redemptions: List discount redemptions with discount name and code, discount amount and type, order id and the redeemed amount, optionally for one discount or order. No customer details are returned.
• list_order_items: List the line items sold in orders with product and variant names, price in cents and quantity, optionally for one order, product or variant. No customer details are returned.
• list_subscription_items: List subscription items with subscription id, price id, quantity and whether billing is usage based, optionally for one subscription or price.

BYOK key

You bring your own Lemon Squeezy Catalog API key (https://app.lemonsqueezy.com/settings/api). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.lemonsqueezy.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Lemon Squeezy Catalog (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Lemon Squeezy Catalog (BYOK) is. Lemon Squeezy Catalog (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Lemon Squeezy Catalog data: Read your Lemon Squeezy variants, prices, discounts and redemptions, order items, subscription items and file listings with your own API key. You bring your own Lemon Squeezy Catalog API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Lemon Squeezy Catalog call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.lemonsqueezy.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Lemon Squeezy Catalog rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Lemon Squeezy Catalog receives. The request we make on your behalf, including the key and the arguments, under Lemon Squeezy Catalog's own terms and privacy policy. Lemon Squeezy Catalog acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Lemon Squeezy Catalog gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Lemon Squeezy Catalog data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Lemon Squeezy Catalog (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Lemon Squeezy Catalog at any time to end all access.

Children. Lemon Squeezy Catalog (BYOK) is a general-audience service operated by the adult using the assistant, under Lemon Squeezy Catalog's own age rules.

Changes. We will post changes here with a new effective date.
