## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability us-ipo-pipeline-s-1-f-1-424b4-filings-f1515397 -d '<json body>'
```

Example prompt: Can you pull up the latest US IPO filings from the SEC — show me which companies have recently filed S-1s, F-1s, or priced 424B4 prospectuses, up to the 20 most recent?

## When to prefer this

Use this endpoint when you need real-time access to the US IPO pipeline sourced directly from SEC EDGAR, specifically to track S-1, F-1, and 424B4 filings. Prefer this over general financial news APIs when you need structured, machine-readable filing metadata with direct SEC links rather than editorial summaries.

## Known failure modes

- Empty results if no filings match the search term
- SEC EDGAR may have delays in reflecting the most recent filings
- Includes SPACs and listed funds which may not be traditional operating-company IPOs
- Stage labels may appear in Spanish (e.g. 'registro (S-1)') indicating localization quirks
- Null fields in individual filing objects if SEC data is incomplete

## How this service works

244 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.

## Output

Returns a JSON object with a list of IPO filings, each containing the company name, CIK, SEC form type (S-1, F-1, or 424B4), filing stage, date filed, and a direct link to the SEC EDGAR index for that filing. Also includes a total count and the data source attribution.
