What you give it

Every field is optional unless marked; sensible defaults do the rest.

Field	Type	What it does	Default
`products`	array	REQUIRED. Your product list as JSON: one entry per retailer product page, each with url (the product page), mapPrice (your minimum advertised price), optional currency (ISO code, default USD) and optional label. Example: [{ "url": "https://shop.example.com/products/widget", "mapPrice": 129.95, "label": "Widget Pro" }]. Up to 500 products per run. Tip: the README has a copy-paste AI prompt that converts a pasted price list or spreadsheet into this JSON.	[{"url": "https://www.clarionsafety.com/products/safety-signs/hazardous-material-signs/chemical-hazard-signs/warning-corrosive-materials-sign-f1243", "mapPrice": 5, "currency": "USD", "label": "Demo \u2014 Warning sign F1243 (demo MAP $5)"}, {"url": "https://jococups.com/usa/product/12oz-joco-cup/", "mapPrice": 19, "currency": "USD", "label": "Demo \u2014 JOCO Cup 12oz (demo MAP $19)"}, {"url": "https://monin.com/us/vanilla-syrup", "mapPrice": 10, "currency": "USD", "label": "Demo \u2014 Monin Vanilla 750 ml (MAP $10)"}]
`alertOn`	string	What counts as an alert. 'violations' alerts when a product newly drops below its MAP or an existing violation cuts deeper. 'violations-and-recoveries' additionally alerts when a violating product returns to or above MAP.	`violations`
`emitBaseline`	boolean	On the first run for a product, push its current price as a baseline item (flagged isBaseline, charged at the low baseline price). Turn off to seed silently: the first run then records state without pushing items.	`True`
`resetState`	boolean	Discard everything this monitor remembers and start over: the next run is a fresh baseline for every product. Use after large catalog or MAP policy changes.	`False`
`maxItems`	integer	Upper bound on items pushed per run. Alerts are pushed before baseline snapshots, so a low cap never hides a violation. Transitions that do not fit alert on the next run.	`500`
`stateStoreName`	string	Named key-value store holding what the monitor has already seen. Use a different name per independent monitor (e.g. one per brand) so their memories never mix.	`map-monitor-state`

What you get back

One JSON object per result, with exactly these fields - no seller identities, no contact data, ever.

Field	Type	Meaning
`productUrl`	string	The monitored product page URL, exactly as provided in the input.
`label`	['string', 'null']	Your label for this product from the input, if provided.
`retailer`	string	Retailer domain the price was read from.
`productName`	['string', 'null']	Product name as published on the page's structured data, when available.
`status`	string	Check outcome. 'violation' = advertised below your MAP. 'unreadable' = the page exposes no trustworthy structured price (never guessed, never charged). 'unreachable' = the page could not be fetched. 'currency-mismatch' = page currency differs from the input currency.
`isViolation`	boolean	True when the advertised price is below your MAP.
`isBaseline`	boolean	True on the first check of a product: a price snapshot that seeds the monitor, not a transition alert.
`isUpdate`	boolean	True for every non-baseline item: the situation changed since the last run (new violation, deeper cut, recovery, or check-status change).
`advertisedPrice`	['number', 'null']	The price a shopper currently sees on the page. For multi-variant products this is the lowest advertised variant (see priceIsVariantLow).
`priceHigh`	['number', 'null']	Highest advertised variant price when the page advertises a range; null for single-price products.
`priceIsVariantLow`	boolean	True when advertisedPrice is the low end of a variant price range rather than a single price.
`currency`	string	ISO currency of mapPrice and advertisedPrice, from your input.
`currencyVerified`	boolean	True when the page itself confirmed the currency; false when the page exposes only an ambiguous symbol or none and your input currency was assumed.
`mapPrice`	number	Your minimum advertised price for this product, from the input.
`deltaAbs`	['number', 'null']	advertisedPrice minus mapPrice. Negative = advertised below MAP (the violation depth).
`deltaPct`	['number', 'null']	deltaAbs as a percentage of mapPrice, rounded to 2 decimals. Negative = below MAP.
`availability`	string	Stock status when the page's structured data exposes it.
`priceSource`	['string', 'null']	Which extraction path read the price: json-ld, shopify-json, price-meta, microdata or woo-markup. Structured sources (json-ld) are the most reliable.
`checkedAt`	string	ISO timestamp of this check.
`note`	['string', 'null']	Why a page was unreadable/unreachable or which currencies conflicted; null on clean reads.
