# DeepXiv · Filings (`filings`)

~1.32M corporate filings and regulatory documents across US and China; the vector layer and the Postgres layer are kept in sync (semantic plus lexical): ~395k EDGAR 8-K events, 154k 6-K, 188k 13D/13G ownership filings, 47k structured 10-K/20-F, 105k 10-Q quarterlies, 32k DEF 14A, 28k Form 425, 7k S-1, 89k SEC comment-letter documents (CORRESP and UPLOAD), 119k Chinese periodic reports, 142k Chinese interim announcements, 10k exchange inquiry letters and discipline decisions, 2.4k CSRC penalty decisions (measured 10-15; Synced daily; exact counts are in corpus (live) — per-source counts in corpus.sources). **Default search excludes 10-Q** (numerous and topically similar, they would crowd out everything else); filter on form or doc_family to include them (e.g. form=10-Q, doc_family=periodic). One-liners, counterparties, amounts, MD&A drivers, inquiry points and violation types are model-extracted; company name / tickers / SIC come from EDGAR submissions.

Corpus: 1,318,627 documents, updated 2026-10.

## Setup

```bash
pip install -U deepxiv-sdk      # deepxiv registers a token on first use
```

With a registered key (https://data.rag.ac.cn/register), `search` and `read` are fair use: 60/min, 5 at once, 5,000/day; on the auto-registered token they spend the deepxiv daily limit at the credits listed below. `ask` draws on the daily ask allowance (resets 00:00 UTC; a site-wide daily total can run out early at peak times), or 3 lifetime trial asks on the auto-registered token. On 429, back off for `Retry-After` seconds. Data goes to stdout; cost, quota and sources go to stderr. Exit 0 ok, 1 API error, 2 usage error. The general CLI guide is the `deepxiv-cli` skill.
