# Brazil Open Finance directory — public participants list

## Access
`GET https://data.directory.openbankingbrasil.org.br/participants` — no
Authorization header, no API key, no query parameters. Served straight
from S3 via CloudFront (`server: AmazonS3`, `x-cache: Hit from
cloudfront`), `cache-control: public, max-age=900` (15 min).

## Shape
A plain JSON array (not `{data: [...]}`), 104 top-level organisation
objects at observation time, 4,518,652 bytes total. Each organisation
carries `OrganisationId`, `Status` (`Active`), `LegalEntityName`,
`CountryOfRegistration`, and a nested `AuthorisationServers[]` array —
one org can list several authorisation servers, each with its own
`Issuer`, `OpenIDDiscoveryDocument` (OIDC .well-known URL),
`CustomerFriendlyName`, and a free-text `Flags` object whose keys are
Portuguese category names ("Habilitação Pix Tester", "Índice de
disponibilidade do Pix") rather than a fixed enum — the flag schema is
effectively per-release and must be read as free text, not matched
against a documented set.

## No pagination, no filtering
There is no `?limit=`/`?offset=`/`?status=` on this endpoint — the only
option is to pull the entire array and filter client-side. At 4.5 MB
this is a flat, unbounded single-request payload; an agent expecting a
paginated directory (as most open-banking registries are) will not find
one here.

## Freshness
`Last-Modified: 2026-10-05T11:53:43Z` observed ~13 minutes before the
probe at 2026-10-05T12:06:14Z — the file is regenerated frequently (same
day), not a static annual export. `etag` changes with each regeneration
(`"e55c8a772fd5664d795d52a0253475df"` at observation time); there is no
`If-None-Match` documentation, but the header is present and a normal
conditional-GET client would work against it unmodified.

## Headers worth noting
`vary: Origin` is set even though CORS is not otherwise documented
anywhere on the page; `x-amz-server-side-encryption: AES256` and
`x-amz-replication-status: COMPLETED` leak that the bucket is
cross-region-replicated infrastructure, not a single-region static site.
No `access-control-allow-origin` header accompanies the `vary: Origin`,
so a browser-based client calling this cross-origin would still be
blocked by CORS despite the server clearly being origin-aware.

How observed: 2026-10-05T12:06:13Z–12:06:14Z, `curl -sI` and `curl -s -o`
against the live endpoint (plain GET, no credentials).
