for (const record of data) console.log(record.name, record.city);BigBasket dark stores by city or pin code
Add city, state or pincode to narrow the stores. Each record lists the pin codes the store was seen serving, so a pin code with no store record is one Rewalto has not seen BigBasket serve.
Fields in each record
From API contract 0.157.0.
| Field | Type | What it means | Example |
|---|---|---|---|
day | string (date) | The IST day the store was last seen. The order and the from and to filters use this day. | "2026-10-15" |
source | string | Where its status comes from: old_sweep (the weekly sweeps up to 17 Oct 2026) or core_sweep (Core’s weekly serviceability sweeps), the one that saw it most recently; for a store no sweep has seen, app_reading (Rewalto’s other readings of the app: its locator, product readings at a pin) or store_list (a store list Rewalto holds). Every source that holds the store is in sources. | "old_sweep" |
platform | string | The quick-commerce app: blinkit, zepto, instamart, bigbasket, flipkart_minutes or jiomart. | "blinkit" |
storeId | string | The app’s own id for the store; for a store known only from a store list, Rewalto’s own id for it (ds-<id>). | "1234" |
name | null or string | The store name the app states; null when it states none. | "HSR" |
city | null or string | The city the sweep found it in, else the city of its first catchment pin; null when neither is known. | "Bengaluru" |
cityTier | null or string | The city’s tier from the Government of India’s house rent allowance classes (DoE O.M. No. 2/5/2017-E.II(B), 7 Jul 2017): tier_1_metro (X), tier_2 (Y), tier_3 (every other city, Z); null where the city is not known. | "tier_2" |
status | string | open (seen in the sweeps since the first one), opened (first seen after the first sweep of its city: a new store) or closed (no longer seen). | "open" |
sweepStatus | string | The sweep’s own status word. old_sweep: active, opened, flicker (missed in one sweep and seen again) or closed. core_sweep: seen (in the app’s newest sweep week) or missed. | "active" |
catchmentPins | array of string | The pin codes the store was seen serving, ascending. | ["560034","560102"] |
catchmentPoints | array of string | Sweep grid points (latitude,longitude) the store was seen serving that the sweep did not place on a pin code; empty for most stores. | ["22.48303,88.35303"] |
firstSeen | string (date-time) | When a sweep first saw the store (UTC). | "2026-10-13T14:30:26.000Z" |
lastSeen | string (date-time) | When a sweep last saw the store (UTC). | "2026-10-15T16:27:27.000Z" |
closedAt | null or string | When the store was marked closed; null while open. | "2026-10-20T00:00:00.000Z" |
seenSweeps | null or integer | How many sweeps saw the store; null for core_sweep stores. | 2 |
missedSweeps | integer | How many sweeps since it was last seen missed it. | 0 |

lon | null or number | Longitude when located; null otherwise. | 77.6389 |
id | string | Rewalto’s own id for the store, stable across refreshes. | "1042" |
sources | array of string | Every kind of source that holds the store (old_sweep, core_sweep, app_reading, store_list). | ["old_sweep","app_reading"] |
homePincode | null or string | The pin code the store is in; null when unknown. pincodeSource says how it is known: an estimate (catchment, catchment_point) is the pin it serves most, not its address. | "560034" |
pincodeSource | null or string | app_reading or store_list (stated), nearest_pin_centre (the pin whose centre is nearest the store’s own point), catchment (its most-seen catchment pin) or catchment_point (the pin nearest a grid point it served); null with no pin. | "catchment" |
area | null or string | The locality the store is in: as a source stated it, else the main locality of its pin code (India Post); null when unknown. | "Koramangala" |
address | null or string | The store’s address as the app or a store list states it; null when none does. | "Sector 110, Gurugram, Haryana, 122017" |
