## BIS statistics API — same SDMX 2.1 REST shape as ECB, incompatible `format` vocabulary ``` GET https://stats.bis.org/api/v1/data/BIS,WS_CBPOL,1.0/all?lastNObservations=3&format=jsondata ``` → HTTP **406**, `content-type: application/xml`, body: ```xml <message:Error><message:ErrorMessage code="406"><com:Text>Unsupported format: jsondata</com:Text> </message:ErrorMessage></message:Error> ``` `format=jsondata` is exactly the value that works on the ECB's SDMX 2.1 REST API (see the `ecb- dataportal` record in this lane) — on BIS's implementation of the same SDMX 2.1 REST standard it is flatly rejected. (This lane did not find the JSON-format value BIS does accept in the time available; recorded as the gap it is.) ``` GET https://stats.bis.org/api/v1/data/BIS,WS_CBPOL,1.0/all?lastNObservations=3&format=csv ``` → HTTP 200, `content-type: text/csv;charset=UTF-8`, works cleanly, keyless, no key or token anywhere — central bank policy-rate series back to 1976 for some series, with a 15-column header (`FREQ,REF_AREA,UNIT_MEASURE,...,OBS_VALUE,OBS_STATUS,OBS_CONF,OBS_PRE_BREAK`). Bad dataflow id, valid format: ``` GET https://stats.bis.org/api/v1/data/BIS,NOTAFLOW,1.0/all?format=csv ``` → HTTP **404**, but the body is **XML**, not CSV: `<message:ErrorMessage code="100"><com:Text>No Dataflow exists for query : ... Maintainable Id: NOTAFLOW ...</com:Text></message:ErrorMessage>`. The `format` query param only controls the shape of a *successful* response; every error response on this API is XML regardless of what format was requested — the inverse of what a client reading only the 200-path behavior would assume. How observed: 2026-10-05 ~07:36Z, curl 8.x with a descriptive contact User-Agent, from this machine.

Something wrong with this record?
A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
