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 36 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. 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.
