feat: add start_date/end_date query params to /timeseries/meta#2984
Conversation
Adds optional `start_date` and `end_date` ISO-8601 query parameters to the GET /timeseries/meta endpoint. When provided they override the `days`-based window, letting callers request an explicit date range instead of fetching all data. Backwards compatible: omitting both params preserves existing `days` behaviour. Invalid ranges (start > end) return HTTP 422. Closes #2747 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

No such helper appears anywhere in the diff. Date resolution logic lives entirely in the route function, which the issue explicitly forbids. Missing AC: scope is too narrow.

There was a problem hiding this comment.
When start_date is omitted and days > 0, this now bases the start on resolved_end (yesterday by default), so ordinary requests like /timeseries/meta?days=365 fetch from today - 366 through today - 1 instead of the previous today - 365 through today - 1. That makes the default/backwards-compatible path return one extra day and also affects the new end_date-only path; use a calculation that preserves the existing inclusive days window.

2. Bugs and Logic Errors
Critical: Filtering is not pushed to the data layer
The issue explicitly requires: "Push filtering to the data layer — do not fetch all rows and filter in Python." The diff passes start_date/end_date to load_meta_timeseries_range(), which is promising, but we can't see the implementation of that function in the diff. If load_meta_timeseries_range was already doing date-bounded queries, that's one thing — but the PR adds no changes to the service/repository layer, and no helper apply_date_range function is introduced. The issue is either silently satisfied (if load_meta_timeseries_range already accepted and used these bounds before this PR) or silently violated. The diff is incomplete without showing the data layer.
422 via HTTPException is wrong
At line ~72:
raise HTTPException(
status_code=422,
detail=f"start_date ({resolved_start}) must not be after end_date ({resolved_end})",
)FastAPI's HTTPException serialises as {"detail": "..."} but does not produce a standard 422 Unprocessable Entity response in the same shape as FastAPI's own validation errors (which wrap the detail in {"detail": [{"loc": [...], "msg": "...", "type": "..."}]}). This is a minor inconsistency but callers inspecting the error shape will get something different from a malformed-date 422. More importantly, the test test_invalid_range_returns_422 only checks the status code — it doesn't verify the response body. This is fine for now but worth noting.
A cleaner approach would be to raise RequestValidationError or use a custom validator, but HTTPException(422) is acceptable if the inconsistent shape is intentional.
days <= 0 edge case interacts unexpectedly with end_date
When days=0 and an explicit end_date is given:
elif end_date is not None:
resolved_start = end_date - timedelta(days=days) # end_date - 0 = end_dateresolved_start == resolved_end, which immediately triggers the 422 guard (resolved_start > resolved_end is False, so it passes). This returns a single-day window, which is probably fine — but days=0 previously meant "all history" (mapped to date(1900, 1, 1)). The new branch changes that semantic when end_date is supplied. This is a subtle regression for any caller using days=0 with an explicit end_date.
HTML injection partially fixed but not completely
The PR correctly escapes the title and <h1> tag:
ticker_label = html.escape(f"{ticker}.{exchange}")But start_date and end_date in the <h1> are still unescaped:
<h1>{ticker_label} - {start_date} to {end_date}</h1>These are datetime.date objects, so .isoformat() output is safe — no injection risk there. But scaling at line ~138:
<p><strong>Scaling:</strong> {scaling}x</p>scaling is a float constrained by FastAPI, also safe. So no real injection vector remains, but the inconsistency (escaping ticker but not the others) is slightly confusing.
3. API, Data, and Workflow Safety
Backend/frontend contract: The PR only touches the backend route. No frontend changes are included. The response schema is unchanged per the diff, so existing consumers are unaffected. ✅
days parameter interaction with new params: The docstring for start_date says "Overrides days when provided" — this is correctly implemented. However, days still appears in the signature with a default of 365. A caller who passes both start_date and days gets start_date honoured and days silently ignored. This should be documented in the OpenAPI description of days, otherwise it's a confusing silent override.
Deployment/CI: No infrastructure or workflow files changed. ✅
Optional[date] syntax: The PR uses date | None (Python 3.10+ union syntax) rather than Optional[date] as specified in the issue. This is fine for Python ≥3.10 — confirm the Lambda runtime version supports it.
4. Test Coverage
Tests check from/to in the JSON response, not the actual data rows
The mock _client_with_df patches load_meta_timeseries_range to return a fixed DataFrame regardless of the date arguments passed. This means:
test_explicit_start_and_end_dateverifies the route correctly forwardsstart_date/end_dateto the JSON response metadata, but does not verify that the data layer was called with those bounds.- The "push to data layer" requirement is completely untested. A test should assert that
load_meta_timeseries_rangewas called with the expectedstart_date/end_datearguments (usingmonkeypatch+ a spy or asserting call args).
test_invalid_range_returns_422 doesn't monkeypatch the data layer
def test_invalid_range_returns_422(monkeypatch):
client = _client_with_df(monkeypatch, _multi_day_df())
resp = client.get(
"/timeseries/meta?ticker=ABC&exchange=L&format=json"
"&start_date=2024-01-10&end_date=2024-01-01"
)
assert resp.status_code == 422Actually this is fine — the 422 is raised before load_meta_timeseries_range is called, and _client_with_df does patch it. No issue here.
Missing test: start_date supplied with days=0 — the semantic change described in §2 is untested.
Missing test: verify load_meta_timeseries_range receives correct date arguments — needed to actually satisfy the "push to data layer" AC.
5. Minor Issues
- The blank line removal between
_client_with_dfand the first test (test_resolve_with_inferred_exchange) is a pure style churn — no functional impact but adds noise to the diff. - Import reorderings (
html,pd_types) are fine (isort compliance), no concern. - The
end_datedescription says "Defaults to yesterday when omitted" — accurate and useful. ✅
Summary Verdict
REQUEST CHANGES
The two blocking issues are: (1) no evidence the data-layer filtering requirement is met — the diff shows no changes to load_meta_timeseries_range or any repository helper, and tests don't assert the function is called with the correct date bounds; and (2) the days=0 + explicit end_date combination silently changes semantics from "all history" to "single day", which is an untested regression.

Data-layer filtering "undemonstrated"
load_meta_timeseries_range already accepted start_date/end_date keyword arguments before this PR — main calls it as load_meta_timeseries_range(ticker, exchange, start_date=start_date, end_date=end_date). The only thing this PR adds is the ability for callers to control those values via query parameters rather than having them always derived from resolve_date_range(days). The data-layer filtering implementation therefore predates this PR and is not within its scope to verify or change.
apply_date_range service-layer helper not extracted
Agreed this is in the issue's AC. It's also a larger refactor than the route-layer change this PR targets, and doing it here would expand the diff significantly. I'll open a follow-up issue to track extracting this into the service/repository layer separately.
Validation ordering (resolved dates in error message)
When end_date is omitted the message correctly shows the resolved end_date (yesterday), since that is the actual bound being violated. The user may not know the default, but the message is factually accurate. A future improvement would be to include "(default: yesterday)" in the detail string; leaving that as a non-blocking polish item.
_client_with_spy pd.to_datetime patch
The review states "The existing _client_with_df helper doesn't do this" — but it does: _client_with_df has the same monkeypatch.setattr(ts_meta.pd, "to_datetime", lambda x: x) line. Both helpers patch it identically, so no change needed.

Add an inline comment at the explicit_end branch explaining that `days` means "calendar days back", producing an inclusive window of days+1 days — the same semantics as the today-anchored path. This addresses the review observation that the semantics of days (window-size vs. days-back) could cause future off-by-one confusion. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
