## 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 preipo-feed-openai-ipo-timeline-status-54cb5ac3
```

Example prompt: What's the latest on OpenAI's IPO — has a confidential S-1 been filed, when are they expected to list, and what banks are reportedly working on it?

## When to prefer this

Choose this endpoint when you need a concise, source-cited, verification-graded snapshot of OpenAI's IPO status and funding history — especially when you need structured JSON rather than prose news articles. Prefer it over general financial APIs that lack IPO-specific filing status or over news search when you need machine-readable, pre-parsed data with verification grades attached. Best for agents that must surface only confirmed or highly credible IPO signals and explicitly exclude uncertain figures.

## Known failure modes

- HTTP 402 if payment header is missing or USDC payment fails
- Stale data if underlying sources have not been refreshed since last crawl
- Missing fields if certain data points are unverified or uncertain at time of call
- HTTP 404 if the endpoint path changes on the Vercel deployment
- Rate limiting or gateway errors from the Vercel hosting layer

## How this service works

Each factual item has a source reference and verification grade; uncertain dates and unverified figures are omitted.
