# filing-firehose

Python client for the [FilingFirehose](https://filingfirehose.com) SEC EDGAR
API — body-text-parsed 8-Ks (with buried-event detection), activist-tagged
Schedule 13D/G filings, and ATM offerings extracted from S-3 / 424B5 prospectus
supplements.

## Install

```
pip install filing-firehose
```

## Quick start

The free public tier returns the last 72 hours of filings — no API key required:

```python
from filing_firehose import FilingFirehose

ff = FilingFirehose()

# Recent 8-Ks where the body language flags items the filer didn't report
buried = ff.recent_8k(suspected_buried_only=True, limit=10)
for f in buried:
    print(f"{f.company_name}: filer reported {f.filer_reported_items}, "
          f"body suggests {f.suspected_buried_events}")

# Recent activist 13D / 13G filings
for f in ff.recent_13d(activist="Saba"):
    print(f"{f.company_name} — {f.percent_of_class}% by {f.activist_filers}")

# Recent ATM offerings with shelf size > $50M
for f in ff.recent_atm(min_shelf_million_usd=50):
    print(f"{f.company_name}: ${f.shelf_size_million_usd:.1f}M via {f.sales_agents}")
```

For the full historical archive, get an API key at
[filingfirehose.com](https://filingfirehose.com):

```python
ff = FilingFirehose(api_key="ff_live_...")

# Search the entire archive for cyber events
for f in ff.search_8k(items="1.05", since="2026-01-01"):
    print(f.company_name, f.filed_at)
```

## Async

```python
import asyncio
from filing_firehose import AsyncFilingFirehose

async def main():
    async with AsyncFilingFirehose() as ff:
        filings = await ff.recent_8k(items="1.05,5.02")
        for f in filings:
            print(f.company_name, f.detected_items)

asyncio.run(main())
```

## Why this client

The wedge: most SEC filings APIs trust the filer-reported item codes on
8-K filings. We body-text-classify every filing and surface a
`suspected_buried_events` field flagging when the body language doesn't match
the filer's claimed item codes. From a [21-day analysis of 4,251 8-Ks](https://filingfirehose.com/research/buried-events),
**7.3% of Item 8.01 filings contain language suggesting a more specific item
should have been used** — including buried cyber incidents (1.05), officer
departures (5.02), and material agreements (1.01).
