## Parameters

| Name | In | Required | Type | What it means | Example |
| --- | --- | --- | --- | --- | --- |
| `retailer` | query | no | string | Only this retailer (a key from /v1/data/retailers). Use blinkit for Blinkit. | `"blinkit"` |
| `pincode` | query | no | string | Only readings for this six-digit pin code, or national for readings that are not pin-scoped. | `"110092"` |
| `location` | query | no | string | A Core location id from the free lookup (GET /v1/data/locations, /cities or /stores): a pin, a city, an area or a dark store. It resolves to an explicit list of pin codes (see GET /v1/data/locations/filter). Never combine with pincode. More than one pin needs confirmPins. A store id (IN:store:<retailer>:<store id>) means the pin codes that dark store serves (its catchment as the sweeps saw it). Readings are kept per pin code, not per store, so it reads every kept reading at those pin codes, whichever store served them; no reading is attributed to the store itself. | `"IN:city:karnataka:bengaluru"` |
| `confirmPins` | query | no | string | Your consent to a multi-pin read: the number of pins the location resolves to, as GET /v1/data/locations/filter showed it. A different number is refused with the current count, so a place is never silently broadened. | `"112"` |
| `brand` | query | no | string | Only records with exactly this brand text, as the retailer wrote it (exact match, case-sensitive). | `"Aashirvaad"` |
| `productId` | query | no | string | Only records matched to this Rewalto product id. | `"0d6b4a52-4b6e-4c1a-9a7e-5b0d2f8f1a11"` |
| `retailerSku` | query | no | string | Only this retailer product id (use together with retailer). | `"prd-88213"` |
| `from` | query | no | string (date-time) | Only readings at or after this time. Default: 30 days before now. | `"2026-10-01T00:00:00Z"` |
| `to` | query | no | string (date-time) | Only readings before this time. Default: now. | `"2026-10-15T00:00:00Z"` |
| `limit` | query | no | string | How many records to return, 1 to 500. Default 100. | `"100"` |
| `cursor` | query | no | string | The nextCursor of the previous page, sent back with exactly the same filters. A cursor from other filters is refused. | `"eyJ0IjoiMjAyNi0xMC0xNFQwOToyNzowMC4wMDBaIiwiaSI6NDgyMTAzNzcsImYiOiJhYmMxMjMifQ"` |
