It is fully keyless — no API key, no registration, no `Authorization` header checked anywhere in these probes. ## Shape - Base: `https://stats.bis.org/api/v1/` - Dataflow catalog: `GET /dataflow/{agency}/{resource}/{version}?format=sdmx-json` (e.g. `/dataflow/BIS/all/latest`) returns every dataflow (`BIS_REL_CAL`, `WS_CBPOL`, …) as SDMX-JSON structure messages (20+ KB for `all`). - Data: `GET /data/{dataflowId}/{seriesKey}?format=sdmx-json|csv&lastNObservations=N`. `seriesKey` is dimension-dot-joined (`D.US` = Frequency=Daily, Reference area=US) — the dimension order and allowed codes are discoverable only from the dataflow's own structure, not from the URL. - `format=sdmx-json` (default) returns the full SDMX-JSON data message: `data.dataSets[].series` keyed `"seriesIndex:0"`, observations keyed by index position into `structure.dimensions.observation[0].values[]` (so `"0":["3.875",0,0,null]` means `TIME_PERIOD` index 0). `format=csv` returns a flat, fully denormalized CSV with every dimension/attribute as its own column (`UNIT_MEASURE`, `DECIMALS`, `SOURCE_REF`, `TITLE`, …) and the human-readable `TITLE` attribute repeated on every row. - Every response carries `content-disposition: inline; filename=".json"` (or `.csv`) even though it is served inline, not downloaded, plus a session `JSESSIONID` cookie and a second opaque session cookie — neither is needed on the next call (cookie not sent, still 200). - No rate-limit header of any kind was observed (`x-ratelimit-*`, `retry-after` absent on 7 calls in ~15s). ## Error shape — HTTP 404 for everything, body tells you which - Unknown dataflow id (`/data/NOPE_FLOW/D.US`) → **404**, `{"errors":[{"code":404,"message":"No Dataflow exists for query : ... Maintainable Id: NOPE_FLOW ..."}]}`. - Known dataflow, series key with a reference-area code that dataflow doesn't carry (`/data/WS_CBPOL/D.ZZZ`) → also **404**, but a different message: `{"errors":[{"code":404,"message":"No data for data query against the dataflow: urn:sdmx:...Dataflow=BIS:WS_CBPOL(1.0)"}]}` — same status code, same envelope shape (`errors[].code/message`), but "dataflow doesn't exist" and "dataflow exists, key doesn't match any series" are only distinguishable by reading the message text, not the status. ## How observed 2026-10-28T23:47:02Z–23:47:37Z, `curl` 8.x with the default UA, light-client flags (`--max-filesize 20000000 -m 20`), 6 GET calls ~a few seconds apart, no key sent, no account held. Probes: `/api/v2/data/...` (404, old path), `/api/v1/dataflow/BIS/all/latest`, `/api/v1/data/WS_CBPOL/D.US?lastNObservations=2&format=sdmx-json`, the same with `format=csv`, and the two 404 cases above.
