Not a third-party API marketplace

All our APIs are built and maintained in-house by our engineering team. For our customers, this provides several key benefits:

High-quality Data

We thoroughly vet all data sources to ensure that they are reliable and accurate before integrating them into our APIs.

Direct Support

All APIs are built and maintained in-house, which translates to faster bug fixes and direct support from our engineering team.

Security and Compliance

We follow industry-standard best practices for API security and perform regular audits to keep all user data safe.

Best Performance

Third-party API marketplaces make extra network requests which increase latency. Our APIs interface with data sources directly.

How we source our data

We know how important high-quality data is. Our rigorous 3-step process to vet all data sources carefully before integrating them into our API products.

1. Data provider audit

We carefully inspect not only the data source itself but also the provider's reliability, reputation, and business history.

In practice, this means that we use official primary sources whenever possible and only work with reputable data vendors.

2. Data quality inspection

Our engineering team manually inspects every data source to verify its accuracy and cleans the data before ingesting it into our systems.

For highly technical APIs we will also bring in industry experts to help validate the data.

3. Data coverage validation

We also manually check all datasets for sufficient coverage. This often involves benchmarking against industry leaders and working with customers directly to make sure that we can service their use cases.
