What you can do with Lightspeed Retail (X-Series) in Claude and ChatGPT
For retailers who run stores and tills on Lightspeed Retail (X-Series).
Check sales totals and the till's payment totals
The AI reads sale count, net, tax and gross totals for a period, by outlet and payment type, and the payment totals of a register since it opened.
Find a sale by date, customer or invoice number
The AI searches sales by date range, state, outlet, register, user, customer, payment type, product or invoice number and opens one with its lines and payments.
Check stock on hand and reorder levels
The AI finds products by SKU, brand, supplier or tag and reads stock on hand per outlet with reorder threshold and amount, so you see what to reorder.
Track supplier stock orders and transfers
The AI lists stock orders, outlet transfers, stocktakes and returns by status and reads the product lines of one with ordered and received quantities.
Look up, add or update a customer
The AI searches customers by email, name, phone or code and reads balance and spend. It can create a new customer or change fields of an existing one.
Changes dataChange a product's price, stock count or reorder level
The AI reads a product and its stock first, then sets the selling price, or the stock on hand and the reorder point and amount of one product at one outlet.

Read only · 26
- Get retailer
lightspeedxseries_get_retailerThe connected store: id, name, domain prefix, store URL, country, currency, time zone, tax-exclusive setting, loyalty and gift-card settings. Good first call (use the time zone to turn a local day into UTC for sales searches). - List outlets
lightspeedxseries_list_outletsList the store's outlets (locations): id, name, address, currency, time zone, default tax. Use the outlet id to filter sales, stock and stock orders. Paginate with next_after. - Get outlet
lightspeedxseries_get_outletOne outlet by id. - List registers
lightspeedxseries_list_registersList registers (tills): id, name, outlet_id, is_open, open/close times and invoice numbering. Paginate with next_after. - Get register payments summary
lightspeedxseries_get_register_payments_summaryPayment totals by payment type for one register since it was opened (the end-of-day / cash-up view). - List taxes
lightspeedxseries_list_taxesList tax groups and their rates (id, name, is_default, rates). The vendor returns the whole list in one reply (no cursor). - List users
lightspeedxseries_list_usersList the store's users (staff): id, username, display name, email, account type (cashier, manager, admin), enabled flag, restricted outlets. Paginate with next_after. - Get user sale totals
lightspeedxseries_get_user_sale_totalsSales totals for one staff user, as the vendor computes them (no date filter; use sales_summary for a period). - List products
lightspeedxseries_list_productsList products (variants) in the catalog: id, family_id, sku, variant_name, prices (price_excluding_tax / price_including_tax), active flags, codes, suppliers, version. The product NAME lives on the product family: add includes=["families"] to get it. Paginate with next_after (stop when data is empty). With sku set, only that SKU is looked up and the other filters are ignored. For text/brand/supplier filters use search_products; for stock use get_inventory_levels. - Get product
lightspeedxseries_get_productOne product (variant) by id, with its prices, codes, suppliers and outlet taxes. - Search products
lightspeedxseries_search_productsFilter products by SKU, brand, supplier, tag, product type or variant parent. Uses offset paging: pass next_offset to continue (null = last page). - Get inventory levels
lightspeedxseries_get_inventory_levelsStock on hand per product per outlet: product_id, location_id (= outlet id), current_inventory_level, reorder threshold/amount, quantity_to_procure, average cost, total cost, supplier. Filter by outlet_ids, product_ids (or root_product_ids for variant families), supplier_ids; to_be_procured_only keeps products with a positive quantity_to_procure (the vendor's re-order suggestion, which accounts for open orders); for a plain below-reorder-point list, compare current_inventory_level with reorder_threshold yourself. Offset paging: pass next_offset to continue (null = last page). Read-only even though the vendor takes the filter as a POST body. - List brands
lightspeedxseries_list_brandsList product brands (id, name). Paginate with next_after. - List tags
lightspeedxseries_list_tagsList product tags (id, name). Paginate with next_after. - List suppliers
lightspeedxseries_list_suppliersList suppliers: id, name, default markup and contact details. Paginate with next_after. - List stock orders (consignments)
lightspeedxseries_list_consignmentsList consignments: supplier stock orders (type SUPPLIER), transfers between outlets (OUTLET), stocktakes (STOCKTAKE) and returns (RETURN), with status (OPEN, SENT, DISPATCHED, RECEIVED, STOCKTAKE_*, CLOSED, CANCELLED), outlet, supplier, due and received dates, totals. Paginate with next_after. - Get consignment
lightspeedxseries_get_consignmentOne consignment (stock order, transfer, stocktake or return) by id. - List consignment products
lightspeedxseries_list_consignment_productsThe product lines of one consignment: product_id, SKU, ordered count, received quantity, cost. Paginate with next_after (stop when data is empty). - List sales (change feed)
lightspeedxseries_list_salesSales in version order, oldest changes first: the way to sync everything that changed. It has NO date filter: for a period use search_sales or sales_summary. Each sale: id, date, invoice_number, state, customer_id, source (outlet, register, user), payments, line_items, totals. Paginate with next_after (stop when data is empty). - Get sale
lightspeedxseries_get_saleOne sale by id with its line items, payments, taxes and totals. - Search sales
lightspeedxseries_search_salesFind sales by date range (UTC), state, outlet, register, user, customer, payment type, product or invoice number. Uses offset paging: pass next_offset to continue (null = last page). Replies can be large: for totals over a period use sales_summary instead of paging through this. - Sales summary (totals for a period)
lightspeedxseries_sales_summaryTotals for a period computed here from up to max_pages x page_size sales, so a report needs ONE tool call instead of dozens: sale count and net / tax / gross (tax-inclusive) totals, plus breakdowns by state, UTC day, outlet and payment type name, and the top products by quantity. By default only closed sales are counted (states containing 'closed'); set counted_states to change that. Dates are UTC (convert local days with the retailer's time zone). If the reply says truncated, call again with offset = next_offset and add the figures up. Uses GET /search?type=sales. - List customers
lightspeedxseries_list_customersList customers in version order: id, customer_code, name, email, phone, balance, loyalty_balance, year_to_date, customer group. To find one by name or email use search_customers. Paginate with next_after (stop when data is empty). - Search customers
lightspeedxseries_search_customersFind customers by email, first name, last name, company name, phone, mobile or customer code. Uses offset paging: pass next_offset to continue (null = last page). - Get customer
lightspeedxseries_get_customerOne customer by id: contact details, addresses, customer group, balance, loyalty balance, year-to-date spend. - List customer groups
lightspeedxseries_list_customer_groupsList customer groups (id, name). Use the id as customer_group_id when creating or updating a customer. Paginate with next_after.
Changes data · 4
- Create customer
lightspeedxseries_create_customerWRITE: create a new customer. Give at least a first name, last name or company name. Check search_customers first so you do not create a duplicate. - Update customer
lightspeedxseries_update_customerWRITE: change fields of an existing customer. Only the fields you pass change: the tool first reads the customer and sends the vendor its full record with your changes applied (the vendor's update is a full PUT). Cannot delete a customer or change balances. Lightspeed offers no partial update for customers, so a change made by someone else in the moments between the tool's read and its write can be overwritten. - Update product prices
lightspeedxseries_update_product_pricesWRITE: set the selling price of one product (variant). Pass price_excluding_tax or price_including_tax as a decimal string such as "24.99" (set one; the store's tax setting decides which the till uses). Nothing else on the product changes. Read the product first and confirm the new price with the user. - Set product stock and reorder levels
lightspeedxseries_set_product_stockWRITE: set the stock on hand (current_amount) and/or the reorder point and reorder amount of ONE product at ONE outlet. current_amount is the NEW TOTAL on hand, not a change: it overwrites the count, so sales made since you last read it are lost from the count. Read get_inventory_levels first and confirm the number with the user. Other outlets and all other product fields stay as they are. PATCH /products/{product_id} (outlet_inventories).
Your usefulapi plan · 4
- Usage status (free-tier meter)
lightspeedxseries_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
lightspeedxseries_request_featureTell usefulapi that the user needs something the Lightspeed Retail (X-Series) tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. - Upgrade to Pro or Pro+
lightspeedxseries_upgradeGet a paid plan for Lightspeed Retail (X-Series) (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
lightspeedxseries_cancel_subscriptionCancel the caller's Lightspeed Retail (X-Series) Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run lightspeedxseries_upgrade later to undo the cancel before the period ends. Does not count against the meter.

Is this an official Lightspeed Retail (X-Series) product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Lightspeed Retail (X-Series). The server calls the Lightspeed Retail (X-Series) API with your own Lightspeed Retail (X-Series) access, so it sees only the data that your account can see.
Can I connect Lightspeed Retail (X-Series) to Claude or ChatGPT?
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
What do I need to connect?
A Lightspeed Retail (X-Series) account. You sign in to Lightspeed Retail (X-Series) and approve the access. You do not need an API key.
Do I add an Authorization header to the client config?
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: you sign in with your Lightspeed Retail (X-Series) account. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
How do you keep my Lightspeed Retail (X-Series) credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Lightspeed Retail (X-Series) API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. You can revoke the access in Lightspeed Retail (X-Series) at any time.
Can the AI change my Lightspeed Retail (X-Series) data?
Yes, if you approve it. 4 of the 30 Lightspeed Retail (X-Series) tools can create or change data. The other 26 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Lightspeed Retail (X-Series) server only. Cancel any time: your paid plan then runs to the end of the paid period. Run lightspeedxseries_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run lightspeedxseries_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run lightspeedxseries_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Lightspeed Retail (X-Series) tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with lightspeedxseries_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Which AI clients can I use?
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
