As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].
bulk_price_changeBulk Price Changeread-onlyApply one pricing rule across a list of prices and show the effect. PREMIUM (license). Percentage first, then the flat amount, then rounding — stated explicitly because the order changes the answer. Typical input {"prices": [19.99, 24.5], "change_pct": 10, "charm_ending": ".99"} returns {"rows": [{"was": 19.99, "now": 21.99}, {"was": 24.5, "now": 26.99}], "total_was": 44.49, "total_now": 48.98, "uplift_pct": 10.09}. Use when repricing a catalogue before export. Not for what a price nets you after Shopify's fees — that is payout_estimate. Errors: on invalid, missing, or malformed input this t…
metafield_key_checkMetafield Key Checkread-onlyValidate a metafield namespace and key before you define it. FREE. Shopify metafield namespaces and keys are lowercase alphanumerics and underscores; a capital letter or a dash is rejected at definition time, usually after the rest of the import has already run. Typical input {"namespace": "custom", "key": "Care-Instructions"} returns {"ok": false, "problems": ["key: dashes and capitals are not allowed"], "suggested_key": "care_instructions"}. Use when designing metafields. Not for the CSV column that carries them — that is product_csv_check. Errors: on invalid, missing, or malformed input t…
payout_estimatePayout Estimateread-onlyEstimate what actually lands in the bank after processing fees. PREMIUM (license). Typical input {"order_total": 84.5, "fee_pct": 2.9, "fee_fixed": 0.3, "orders": 120, "refund_rate_pct": 4} returns {"gross": 10140.0, "fees": 330.06, "refunds": 405.6, "net_payout": 9404.34, "effective_fee_pct": 3.26}. Use for cash-flow planning. Not as an authoritative fee schedule: rates depend on your plan, country and card mix, so pass your own. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"}. Every call is r…
product_csv_checkProduct Csv Checkread-onlyCheck a product CSV's header row against Shopify's current columns. FREE. Catches the failure that wastes the most time: a template copied from an out-of-date guide, using column names Shopify renamed. Typical input {"header_row": ["Handle", "Title", "Body (HTML)", "Variant Price"]} returns {"ok": false, "missing_required": [], "renamed": [{"found": "Handle", "use": "URL handle"}, ...], "unrecognised": [], "verdict": "..."}. Use before an import, on the header row alone. Not for whether the values in the rows are valid — check a handle with url_handle and a metafield key with metafield_key_c…
url_handleUrl Handleread-onlyTurn a product title into a valid, unique Shopify URL handle. FREE. Shopify handles are lowercase, may contain letters, numbers and dashes, and may not contain spaces. Typical input {"title": "Men's Merino Wool Socks (2-Pack)"} returns {"handle": "mens-merino-wool-socks-2-pack", "valid": true, "changed": true, "collisions": []}. Use when generating handles for an import, or checking one you already have. Not for validating a whole header row — that is product_csv_check. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wr…
variant_matrixVariant Matrixread-onlyCount the variants a set of options produces, and flag the ceilings. FREE. Option counts multiply, so three modest lists become a number nobody intended. Typical input {"options": {"Size": ["S", "M", "L"], "Colour": ["Black", "Navy"]}} returns {"option_count": 2, "variant_count": 6, "within_limits": true, "per_option": {"Size": 3, "Colour": 2}}. Use before building an import file, to find out whether the catalogue needs splitting into several products. Not for validating the resulting CSV's columns — that is product_csv_check. Errors: on invalid, missing, or malformed input this tool never r…
