Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sec-edgar-s-1-ipo-filing-changes-b75c685a
```

Example prompt: Pull all new SEC EDGAR S-1 IPO registration filings detected since 2025-01-01T00:00:00Z, limit to 50 results, and only show me ones with a significance score of at least 5.

## When to prefer this

Use this endpoint when you need to programmatically monitor or retrieve new IPO (S-1) registration filings from SEC EDGAR since a specific point in time. Prefer this over manually scraping EDGAR when you want structured data with significance scoring, direct filing links, and change-detection semantics. Ideal for financial research agents, IPO trackers, or automated alerts about companies preparing to go public.

## Known failure modes

- Missing or malformed 'since' parameter returns validation error
- 'since' value in wrong format (not ISO-8601) causes 400 error
- limit out of range (outside 1-500) causes validation error
- min_significance out of range (outside 1-10) causes validation error
- No filings detected in the requested window returns empty changes array
- Service unavailable or Railway hosting downtime returns 5xx error
- Payment not completed (x402 protocol) blocks access

## How this service works

SEC EDGAR S-1 filings matching IPO registration statements since a timestamp — company name, CIK, form, filing date, and a direct link to the filing index.

## Output

A JSON object containing a count of matching filings and an array of change records, each with the company name, CIK, form type (S-1), filing date, a direct URL to the SEC EDGAR filing index, a significance score (1-10), a summary, and the timestamp when the filing was detected.
