## 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 fda-regulatory-catalyst-calendar-91db1a4f
```

Example prompt: Pull the upcoming FDA regulatory catalyst calendar for SRRK from their SEC filings — I want PDUFA dates and any advisory committee meetings, forward-looking only.

## When to prefer this

Use this endpoint when you need FDA regulatory milestone dates for a specific biotech issuer grounded in primary source SEC filings rather than scraped press releases or third-party databases. Ideal for catalyst-driven investment research, event-driven trading signals, or compliance timelines where citation to an official filing is required.

## Known failure modes

- Ticker or CIK not found in SEC EDGAR — returns empty results or error
- No relevant 8-K/6-K filings found within the lookback window — empty event list
- All discovered dates are historical when forward_only=true — empty result
- Invalid ticker symbol — error or empty response
- EDGAR rate limit or upstream unavailability — service error
- Event type filter yields no matching events for this issuer

## How this service works

Forward-looking FDA regulatory catalyst calendar for one biotech issuer, extracted from primary SEC 8-K and 6-K filings. Give a ticker or CIK and get upcoming PDUFA target action dates, advisory committee meetings, Complete Response Letters, priority reviews and PDUFA extensions, each date grounded in a quote from the filing and cited to its accession and EDGAR URL.

## Output

A list of regulatory events for the queried issuer, each with: event type (pdufa, adcomm, crl, priority_review, pdufa_extension), the specific date, a verbatim quote from the SEC filing that grounds the date, the filing accession number, and the EDGAR URL for the source document.
