Herald

Herald builds digital infrastructure for commercial insurance, providing a single unified REST API that lets software platforms quote and bind across many carriers and lines of business. Developers create applications, submit them to carriers, and receive normalized quotes, products, classifications, and files through one integration secured with OAuth2 client-credentials bearer tokens.

Herald publishes 10 APIs on the APIs.io network, including Applications API, Authentication API, Classifications API, and 7 more. Tagged areas include Insurance, Insurtech, Commercial Insurance, Quoting, and Carriers.

Herald’s developer surface includes authentication, documentation, and 7 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/herald: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
