One API for search, discovery, and structured output

Raw CH Accounts Data

  • Endless individual files, delivered daily

    You’re left stitching together thousands of documents just to build a dataset.

  • Strict rate limits on the live API

    Slows down automation and bulk queries, even for basic lookups.

  • No easy way to filter by financials

    You can’t just ask for “companies with assets over £1m” — you have to build that logic yourself.

  • Finding companies is hard without knowing exact names or numbers

    Discovery is guesswork unless you’ve already got a list.

What You Get With DataLedger

  • Structured accounts in a single API

    No need to download, parse, or manage data pipelines - we do it for you.

  • Higher call limits and simpler usage

    Use the API in workflows with realistic, integration ready endpoints

  • Search by financial thresholds instantly

    Filter by equity, liabilities, assets, employee count, industry, location and incorporation date with one query.

  • Autocomplete, SIC and postcode-based discovery

    Find companies even when you only know part of the name - or just the sector and location.
