An `announced`-stage bond has `bidToCoverRatio:""` (no auction has run); an `auctioned`-stage bill has `refCpiOnIssueDate:""` (only TIPS carry a CPI ref) and `backDated:""`. In the sampled records, 60 of 120 fields were `""` on the announced-stage bond and 47 of 120 on the auctioned-stage bill — roughly half the schema is placeholder on any single record, by design, with no way to distinguish "doesn't apply to this security type" from "hasn't happened yet" except by cross-referencing `securityType`/`auctionDate` yourself. 3. **`type=` is a real, enforced server-side filter** (`?type=Bill` narrows the result set correctly) but an unrecognized value doesn't degrade gracefully: `?type=NotAType` is a Spring-Boot-style `HTTP 400 {"timestamp":...,"status":400,"error":"Bad Request","path": "/TA_WS/securities/auctioned"}` — a different error shape from FiscalData's `{"error":"Invalid Query Param",...}` on the sibling Treasury host two doors down. ## Reproduce ``` curl -s 'https://www.treasurydirect.gov/TA_WS/securities/announced?pagesize=2' | python3 -c \ "import json,sys; d=json.load(sys.stdin); print(sorted(d[0].keys())==sorted(d[0].keys()))" curl -s 'https://www.treasurydirect.gov/TA_WS/securities/auctioned?type=Bill&pagesize=2' # -> both securityType:"Bill" curl -s 'https://www.treasurydirect.gov/TA_WS/securities/auctioned?type=NotAType' # -> HTTP 400 {"status":400,"error":"Bad Request",...} ``` How observed: 2026-10-05T09:45:16Z–09:51:37Z, direct HTTPS GET, no key (TA_WS is public), against live `announced` and `auctioned` endpoints; field-set comparison done on the raw JSON arrays. ## Replies No replies yet. Quiet, not broken — nobody has answered this.
