# Latest or dated ETF snapshot

`GET /api/v1/etf/{symbol}/snapshot`

Single ETF snapshot at the latest cycle (default) or at a specific calendar date via ``?date=YYYY-MM-DD``. Returns the full payload: pricing (nav, price, premium/discount), fund characteristics (AUM, expense ratio, yields), top-10 holdings sample, sector weightings (both raw + canonical), asset-class and country exposure, and trailing returns. Returns 410 Gone when the symbol is flagged as delisted_candidate by the upstream cycle.

Since DATA-N4.4 the canonical snapshot is rebuilt purely from Tier S sources (regulated-exchange price + SEC NPORT-P holdings), with no commercial aggregator in the chain. Fields awaiting their replacement source are returned as ``null`` and tagged in the internal ``_sources.deferred`` map: ``nav``/``aum_usd``/``premium_discount_pct`` (DATA-N4.3), ``returns_*`` and ``fifty_two_week_high``/``fifty_two_week_low`` (DATA-N4.1), and ``expense_ratio_pct``/``yield_dividend_pct``/``yield_distribution_pct``/``inception_date`` (DATA-N4.2).

DATA-N4.8.1: when ``price`` is null but a NAV is available, an additive ``price_proxy`` block surfaces the NAV as an explicitly-stale proxy (``basis = nav`` with an ``as_of`` SEC-filing date that can be months old and a ``note`` disclaiming a current quote). ``price`` itself stays null - the proxy is never presented as a live quote. The block is absent when ``price`` is present or when ``nav`` is also null.

## Path parameters

- `symbol` string, required — ETF ticker.

## Query parameters

- `date` string, nullable — Optional snapshot date (YYYY-MM-DD). Defaults to the latest cycle.

## Response `200`

Latest or dated ETF snapshot payload.

- EnvelopeEtfSnapshotPayload
  - `data` EtfSnapshotPayload, required — Full per-symbol snapshot payload.
    - `symbol` string, required — ETF ticker.
    - `name` string, nullable — Fund full name.
    - `category` string, nullable — Fund category.
    - `snapshot_date` string, required — Logical snapshot date (ISO).
    - `snapshot_taken_at` string, nullable — ISO timestamp at upstream fetch time.
    - `manifest_version` string, nullable — Manifest version that produced this snapshot (Unix timestamp).
    - `nav` number, nullable — Net Asset Value. Since DATA-N4.3 sourced from SEC data: re-based from NPORT-P net assets over the audited 485BPOS share count (``_sources.nav.method = monthly_derived``) when available, else the annual audited 485BPOS NAV (``annual_485bpos``). Null only when the prospectus input is missing for this ETF.
    - `price` number, nullable — Regular-session previous close (regulated exchange).
    - `price_proxy` PriceProxy — DATA-N4.8.1 additive NAV price-proxy block. Surfaced ONLY when the snapshot has no exchange price (``price`` is null) but a SEC-derived NAV is available. The NAV is offered as an explicitly-stale reference value - never as a current quote. The ``price`` field itself stays null, so a client keying on ``price`` sees absence, not a fabricated number. Absent when ``price`` is present or when ``nav`` is also null.
      - `value` number, nullable — The NAV value used as the price proxy (equals the snapshot ``nav``).
      - `basis` string, required — Always ``nav`` - signals this is a NAV proxy, not a live quote.
      - `as_of` string, nullable — ISO date the NAV was sourced (the SEC filing date). Period-stale by construction - can be months old. Null when provenance is unavailable.
      - `method` string, nullable — NAV derivation method from ``_sources.nav.method`` (``monthly_derived`` from NPORT-P net assets, else ``annual_485bpos`` for the audited prospectus NAV). Null when provenance is unavailable.
      - `note` string, nullable — Honest staleness disclaimer - the proxy is not a current quote.
    - `premium_discount_pct` number, nullable — (price - nav) / nav * 100. Since DATA-N4.3 the NAV basis is period-stale (SEC-filing as-of, not same-day); see ``_sources.premium_discount_pct.note``. Null when nav or price is null.
    - `fifty_two_week_high` number, nullable — Deferred (DATA-N4.1) - null pending exchange quote history.
    - `fifty_two_week_low` number, nullable — Deferred (DATA-N4.1) - null pending exchange quote history.
    - `aum_usd` number, nullable — Total assets under management in USD. Since DATA-N4.3 sourced from SEC NPORT-P fund-level net assets (exact) or, as a fallback, the 485BPOS audited net assets. Null only when both inputs are missing for this ETF.
    - `expense_ratio_pct` number, nullable — Annual report expense ratio as percent. Since DATA-N4.2 sourced from the SEC 485BPOS Financial Highlights.
    - `yield_dividend_pct` number, nullable — Dividend yield as percent. Since DATA-N4.2 proxied from the SEC 485BPOS net-investment-income ratio (equal to ``yield_distribution_pct`` in v1; see ``_sources``).
    - `yield_distribution_pct` number, nullable — Distribution yield as percent. Since DATA-N4.2 proxied from the SEC 485BPOS net-investment-income ratio.
    - `inception_date` string, nullable — ISO inception date. Since DATA-N4.2 sourced from the SEC N-1A prospectus body ('commenced operations on ...').
    - `top_holdings` ModelsEtfHolding[], nullable — Top-10 holdings sample.
      - `symbol` string, nullable — Ticker of the held position (null for cash, futures, bonds).
      - `name` string, required — Issuer name.
      - `weight_pct` number, required — Portfolio weight as percentage (0.0-100.0).
      - `sector` string, nullable — Canonical Sugra sector or null.
      - `asset_class` string, nullable — High-level asset class (equity, bond, cash, other).
    - `sector_yahoo_raw` SectorWeightRaw[], nullable — Raw sector weight rows as stored on the snapshot blob. Wire field name is historical; prefer ``sector_canonical`` for consumers.
      - `label` string, required — Raw sector label as returned by upstream.
      - `weight_pct` number, required — Weight as percentage.
    - `sector_canonical` SectorWeightCanonical[], nullable
      - `sector` string, required — Canonical Sugra sector slug.
      - `weight_pct` number, required — Weight as percentage.
    - `asset_class_weightings` AssetClassWeightings — Asset-class breakdown for the snapshot.
      - `equity_pct` number, nullable — Equity percentage.
      - `bond_pct` number, nullable — Bond percentage.
      - `cash_pct` number, nullable — Cash percentage.
      - `other_pct` number, nullable — Other (commodities, derivatives) percentage.
    - `country_weightings` ModelsEtfCountryWeight[], nullable
      - `country_code` string, required — ISO 3166-1 alpha-2 country code.
      - `weight_pct` number, required — Country weight in percent.
    - `returns_1m` number, nullable
    - `returns_ytd` number, nullable
    - `returns_1y` number, nullable
    - `returns_3y` number, nullable
    - `returns_5y` number, nullable
    - `returns_10y` number, nullable
    - `data_source` string, nullable — Upstream data-source identifier for the PRICE + HOLDINGS origin. Since DATA-N4.4 the canonical snapshot is rebuilt from Tier S sources: exchange quotes plus SEC N-PORT when both contributed, exchange quotes alone (SEC blob absent, e.g. a commodity-pool ETF) or SEC N-PORT alone (exchange-quote blob absent). The SEC 485BPOS prospectus (DATA-N4.3 + N4.2) additionally supplies NAV / AUM / expense ratio / yields / inception; its per-field provenance lives in ``_sources`` (the top-level slug intentionally still reflects only price + holdings). Legacy blobs may still carry a retired commercial fund-summary token from DATA-N1.
    - `license_attribution` string, nullable — License attribution string.
    - `_sources` object, nullable — DATA-N4.4 per-field provenance (internal metadata, additive). Maps each populated field to its Tier S source. Price carries the exchange ``as_of``; holdings/weightings carry SEC NPORT-P ``rep_pd_date`` + ``accession``. Since DATA-N4.3 + N4.2 the seven fields ``nav``/``aum_usd``/``premium_discount_pct`` and ``expense_ratio_pct``/``yield_dividend_pct``/``yield_distribution_pct``/``inception_date`` are POPULATED from SEC data and carry their own ``_sources`` entry: ``nav`` records ``method`` (``monthly_derived`` when re-based from NPORT-P net assets, else ``annual_485bpos`` for the audited prospectus NAV) + ``as_of``; ``premium_discount_pct`` records ``nav_method`` / ``nav_as_of`` / ``price_as_of`` plus a ``note`` that the NAV basis is period-stale. The ``deferred`` map now carries only the DATA-N4.1 fields (``returns_*`` + ``fifty_two_week_high``/``fifty_two_week_low``) at baseline; any of the seven SEC-sourced fields is re-added to ``deferred`` per-symbol ONLY when its prospectus / NPORT-P input was missing for that ETF.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
