Explore](https://rewalto.com/guides/brand-to-registered-company) ## How these guides are written Every guide is signed by Varun Mahajan, Founder, carries the date it was published and the date it last changed, and describes what Rewalto measures today rather than what it might measure later. A number in a guide comes from a Rewalto reading and is dated where it appears. Where we cannot measure something, the guide says so instead of estimating. Nothing in a guide promises a ranking or a citation from any app or assistant. To see how the readings themselves are taken and checked, read [how The 10-Minute Shelf is measured](https://rewalto.com/10-minute-shelf/method). ## Questions before you start Where should I start? For data access, start with the API guide at rewalto.com/guides/quick-commerce-api-india. For shelf questions, start with the guide to what changes from one pin code to the next. Are the figures current? Each guide states the date its figures were read. Check the date before you reuse a number. Is there a glossary? Yes: quick commerce terms at rewalto.com/glossary/quick-commerce and e-commerce terms at rewalto.com/glossary/ecommerce. ## Put the reading to work. Explore the data behind your question, or ask Finder to help define the next step. [Ask Finder](https://rewalto.com/finder) PUT THE EVIDENCE TO WORK ## Choose a guide by the evidence you need ### Choose and connect your data Start with the India data API guide if you are building an application. Read the MCP guide if an AI agent will use the data. Both explain what to check before connecting, including permissions, source dates and the difference between a catalogue description and a working integration. ### Compare products without losing the context For a price comparison, match the pack, location and check time. For stock analysis, keep not checked separate from out of stock. These small distinctions decide whether a result supports the conclusion you want to draw. ### Check the fit before expanding the request Review coverage and freshness against your actual question. A sample helps you test fields and missing values; it does not establish complete coverage. Use the marketplace guide to distinguish a listing record from evidence about sales or demand.
