Returns a single SEC filing identified by its accession number.
The filing must be within your subscription tier's historical data limit.

The `documents` array contains slide/exhibit image filenames (JPG, PNG, GIF, PDF) extracted from the filing. To build a document URL, replace the filename at the end of the filing `url` with the document filename.

## Query parameters

- `accessionNumber` string, required

## Response `200`

The SEC filing

- FilingInfo: A single SEC filing. Fields that do not apply to a given filing type (e.g. `items` for non-8-K, `periodEndDate` for Form 4/144) are omitted from the response rather than returned as null.
  - `type` string, required: SEC form type
  - `accessionNumber` string, required: SEC accession number
  - `url` string, required: URL to the filing document
  - `dateFiled` string, required: Date the filing was submitted to the SEC (YYYY-MM-DD)
  - `acceptedAt` string, date-time: EDGAR acceptance timestamp of the filing whose date sits next to it (`dateFiled`, or `filingDate` on insider transactions). Always ISO 8601 in UTC with second precision, e.g. `2024-11-01T10:01:36Z`. Optional: omitted when that filing date is absent or the acceptance time is unknown (common for older filings and for the most recent ones, whose acceptance time is filled in after a short delay). Normally on the same calendar day as the filing date. Exceptions: a filing accepted after EDGAR's daily cutoff (5:30 p.m. ET for most forms, 10 p.m. ET for insider Forms 3, 4, 5 and 144) is dated the next business day, and an acceptance late in the Eastern evening is already the next day in UTC.
  - `xbrl` boolean, required: Whether the filing includes XBRL data
  - `amendment` boolean, required: Whether this filing is an amendment
  - `periodEndDate` string: Period end date for the report (YYYY-MM-DD). Omitted for filings without a reporting period (Form 144, 4, etc).
  - `documents` string[]: Ordered list of slide/exhibit filenames (images >= 50KB). To get the full URL, replace the filename in the filing `url` with the document filename. Omitted when no extractable documents are present.
  - `title` string: Descriptive title of the filing. Omitted when the filing has no meaningful title.
  - `items` string[]: Extracted item identifiers. For 10-K/10-Q: section numbers (e.g. "1A", "7"). For 8-K: SEC item codes (e.g. "2.02", "9.01"). For S-1: section keys (e.g. "risk-factors"). Omitted when no items are extracted. Use `/api/filings/item` to retrieve the full content of any listed item.
  - `events` string[]: Developer-friendly event type names for 8-K filings. Omitted for non-8-K filings. See the `event` parameter for the full enum.
