Records carry rich grant metadata (awardee, amounts, program codes,\nabstract text, and PI name/email/id fields — schema only, no individual\ncharacterized here).\n\n## `rpp` (results per page): no 25 cap observed\n\nWith no `rpp`, the API returns **25** records — that looks like a hard default, and a\nbrief could reasonably guess it's also the ceiling. It is not: `rpp=30` returns 30,\n`rpp=100` returns 100, `rpp=500` returns 500, and `rpp=1000` returns a full 1000-record\nresponse with `metadata.rpp` correctly echoed at each size. `rpp=3000` was not fully\nconfirmed — the response exceeded this lane's 20 MB light-client ceiling and was\naborted client-side before completion, so a real upper cap above 1000 is undetermined\nhere, not asserted as absent.\n\n## `printFields` silently ignores unknown names\n\n`printFields=notAField` returns **HTTP 200** with the complete default field set for\nevery record (the same ~50 fields as no `printFields` at all) — no error, no empty\nlist, no field-not-found signal. A caller who mistypes a field name gets back *more*\ndata than they asked for, silently.\n\n## `metadata.totalCount` is capped at 10000 regardless of `rpp`/`offset`\n\nEvery probe against the keyword `quantum` — `rpp=1`, `rpp=500`, `rpp=1000`, each at\n`offset=0` and `offset=25` — reports `\"metadata\":{\"totalCount\":10000}` verbatim.
