Kard

Kard is an independent commerce media network and card-linked-offers (CLO) rewards platform. Its Rewards API lets fintechs, banks, and card issuers enroll cardholders, submit transactions for closed-loop offer matching, surface personalized offers and redemption locations, run attributions and placements, and receive earned-reward webhook notifications — powering embedded loyalty and cashback programs without building the matching infrastructure. Marketers use the same network to reach 47M+ cardholders with performance-based, transaction-driven offers.

Kard publishes 17 APIs on the APIs.io network, including attributions API, Files API, notifications > Notifications API, and 14 more. Tagged areas include Company, Rewards, Card-Linked Offers, Loyalty, and Fintech.

The Kard catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Kard’s developer surface includes documentation, API reference, getting-started guide, quickstart, authentication, engineering blog, support, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/kard: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
