The US S-1/F-1 registration pipeline, straight from SEC EDGAR: every tracked registration statement, including issuer offerings, selling-stockholder resales, direct listings, and registrations that are not public-equity offerings. Each row labels that structure from verified filing evidence. Terms come only from the newest 424B4 when present, otherwise the newest amendment or registration statement; a superseded Approved extraction never substitutes for a pending, rejected, or empty effective filing. Financials come from the filer's own XBRL-tagged statements.

## /v1/ipos

Returns the tracked registrations, newest filing activity first. `offeringType` is `Primary` (including mixed issuer/resale), `Resale`, `DirectListing`, `NonOffering`, or `Unknown`. `NonOffering` and `Unknown` suppress unverified equity price/share fields. `termsAvailability` is `Available`, `NoneStated`, `Unavailable`, or `Pending`; pre-v3 rows stay Pending until replay instead of publishing stale terms. `effectiveProspectus*` identifies the exact source. `financialsAvailability` independently describes the annual companyfacts import. Percent fields are percentages, not fractions.

**Parameters:** `status` (optional: `Filed`, `Priced`, `Listed`, or `Withdrawn`); `filerType` (optional: `Operating` or `Spac` — SEC's SIC 6770 blank-check classification); `limit` (default 25, max 500) and `offset` for paging.

## /v1/ipos/{cik}

Returns one registration's full picture by SEC CIK: the verified offering-type quote, exact effective-prospectus accession and URL, offer terms and quotes, insights, annual financials, and filing chain. `underwritersAvailability` and `riskFactorsAvailability` distinguish pending/rejected extraction from a completed read that stated none. Unknown and NonOffering classifications suppress price/share quotes and underwriters; their underwriter state is `Unavailable` because those equity fields are not publishable. Unknown CIKs return `404`.

**Parameters:** `cik` (path — with or without leading zeros).

```bash
curl "https://api.equibles.com/v1/ipos/1898474" \
  -H "Authorization: Bearer eq_your_api_key"
```

```python
import requests
r = requests.get(
    "https://api.equibles.com/v1/ipos/1898474",
    headers={"Authorization": "Bearer eq_your_api_key"},
)
print(r.json())
```

```javascript
const res = await fetch("https://api.equibles.com/v1/ipos/1898474", {
  headers: { Authorization: "Bearer eq_your_api_key" },
});
console.log(await res.json());
```

Response (trimmed — one risk factor, one financial year, and one filing shown):
