# FDX (Financial Data Exchange) — no public API, confirmed live

## What FDX is
FDX is the US standards body that publishes the FDX API **specification**
(the schema banks and aggregators implement bilaterally); it does not
itself run a public directory or registry API the way UK Open Banking or
Australia's CDR do. `financialdataexchange.org` is an ordinary WordPress
marketing site (`HTTP 200`, `text/html; charset=UTF-8`, 168,409 bytes at
the root).

## The tell
Guessing the obvious `GET https://financialdataexchange.org/api` does
not 404 and does not reach any API — WordPress's own routing 301-redirects
it straight to a **PNG image**:
`Location: https://financialdataexchange.org/wp-content/uploads/2025/12/api.png`
(an uploaded media asset, not a document about an API). No `swagger`,
`openapi`, or `developer.` subdomain reference appears anywhere in the
homepage HTML.

## Gotcha
An agent pattern-matching "`/api` on a standards-body domain probably
returns something API-shaped" gets a **301 to an image file** here — a
completely silent, non-error redirect to binary content that looks
nothing like a refusal. Confirms the brief's framing: FDX is a spec
publisher, not a live service; "no public API" should be recorded rather
than assumed, and this is the live confirmation.

## Scope of what was checked
No `api.financialdataexchange.org`, `developer.financialdataexchange.org`,
`swagger`, or `openapi` string appears anywhere in the 168,409-byte
homepage HTML. The site is a standard WordPress install serving the
FDX API **specification documents** (PDF/HTML standards text, member
directory, certification program pages) rather than any runnable
service — consistent with FDX's actual role as a non-profit standards
body whose members (banks, aggregators, fintechs) each implement the
spec independently and bilaterally, the same structural pattern as the
Berlin Group's NextGenPSD2 (see the companion Berlin Group source in
this lane): the standards body itself exposes no API, only the document
describing one.

How observed: 2026-10-05T12:07:30Z–T12:09:03Z (redirect check), live `curl`
GET/HEAD against `financialdataexchange.org/` and `/api`.
