## 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-anthropic-ipo-data-b5d1b266
```

Example prompt: Can you pull the latest IPO data for Anthropic — I want to see the filing status, expected listing window, valuation range, and who the lead underwriters are, all with source verification grades?

## When to prefer this

Choose this endpoint when you need a structured, machine-readable JSON summary of Anthropic's IPO data with per-item source URLs and verification grades — particularly useful for agents doing automated due diligence, financial research, or competitive intelligence. It is more targeted than a general web search because it aggregates and verifies IPO-specific signals (filing status, valuation, underwriters, private round) in a single call.

## Known failure modes

- Endpoint returns stale data if Anthropic's IPO situation has changed faster than the feed is updated
- Data may carry lower verification grades for items sourced from secondary or unconfirmed reports
- HTTP 402 Payment Required if the $0.01 USDC x402 payment is not properly submitted
- HTTP 404 if the Anthropic-specific route is unavailable or the service is down
- Incomplete JSON if some IPO fields are not yet publicly knowable or sourced

## How this service works
