Screaming Data

Custom datasets from any public source

Name the source and the fields. We scope the dataset with you, build it, and deliver clean JSON on your schedule — through the API or to your webhook. Quoted per project.

Sources we work with

Publicly available websites of every kind. A few examples:

  • Catalogues

    Products, specifications and prices from online shops and brand sites.

  • Listings

    Classifieds, property, jobs, events — any page that lists items.

  • Directories

    Companies, venues and locations, as structured records.

  • Marketplaces

    Offers, prices, ranks and ratings beyond the ready-made marketplace data.

How delivery works

The dataset is yours through the same REST API as everything else — no files to collect by hand, no format of its own.

  • Through the same API

    One login and key, the same response envelope as the marketplace endpoints, and the exact cost in every response.

  • Pushed to your webhook

    Every result posted to your endpoint as soon as it is ready, signed with HMAC-SHA256 and retried with back-off.

  • On your schedule

    Once, daily or hourly. Records keep the same shape on every run, so nothing downstream has to change.

The mechanics are the same as for the marketplace endpoints: response format and webhooks.
