# Utilities for working with data.

Rewalto’s free tools check one question each: whether a brand’s products are listed and in stock at a pin code, whether a price sits below MRP, and where Rewalto reads a brand by city. Each result comes from Rewalto’s own dated readings. Each tool says plainly when it has no reading.

## Questions before you start

Are the tools free?

Yes. The tools are free; any data request shows its cost separately before it runs.

Where do the results come from?

From Rewalto's own dated readings of public app pages, not from a live call to the app at the moment you ask.

What if my pin code is not covered?

The pin-code checker says so ("not collected here yet") instead of guessing. It is not evidence either way.

## Choose the data before choosing the tool

Start with your question, the fields you need and the period you want to compare. Check the current catalogue status before depending on a tool or delivery option.

PUT THE EVIDENCE TO WORK

## Choose a free check for the task in front of you

### Shelf checks start with a product and location

Use availability and price checks to inspect supported readings for a specific brand or product. Review the source, location and observation date before drawing a conclusion. No recent reading and a measured unavailable state mean different things; neither should be silently replaced with the other.

### Website tools help prepare your pages

Use the metadata, structured-data and llms.txt tools to draft a starting point for your own site. Review generated text and markup against the page’s actual content before publishing. A valid file or descriptive title does not guarantee indexing, search visibility or citation by an AI assistant.

### When a single check is not enough

Use a guide to plan a broader comparison, data for structured analysis, a report for a bounded interpretation, or a watch for a repeated change condition. Use these free checks for a focused question. Any later data delivery should have its own rate or quote review.
