The Riksbank developer portal\nregisters apps with subscription keys for its APIs generally; this particular SWEA endpoint did not\nrequire one at the time of this observation.\n\nValid series:\n```\nGET https://api.riksbank.se/swea/v1/Observations/Latest/SECBREPOEFF\n```\n→ HTTP 200, `{\"date\":\"2026-10-05\",\"value\":1.75}` (today's policy rate).\n\nUnknown series — the gotcha:\n```\nGET https://api.riksbank.se/swea/v1/Observations/Latest/TOTALLYBOGUS123\n```\n→ HTTP **204 No Content**, zero-length body, `Content-Length: 0`. No error message, no JSON at all —\njust an empty success-shaped status. Reproduced on a second bogus id with the same result.
