Mastercard Developer Hub for FDX APIs

The Financial Data Exchange (FDX) is a nonprofit industry standards body that created the FDX API, a technical standard for user-permissioned financial data sharing. The FDX API standard, like other data sharing methods used in open banking, gives consumers more control over who can access their financial data. The open banking industry is founded on the principles of interoperability, which are being advanced by forthcoming rulemaking from the The Consumer Financial Protection Bureau (CFPB).

Mastercard Developer Hub for FDX APIs publishes 10 APIs on the APIs.io network, including Application Check Controller API, Consent API, Data Resource APIs API, and 7 more. Tagged areas include Banking, FDX, and Open Banking.

Mastercard Developer Hub for FDX APIs’ developer surface includes authentication, developer portal, signup flow, FAQ, support, engineering blog, and 35 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance 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/mastercard-developer-hub-for-fdx-apis: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
