## 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 catalyst-upcoming-a1bc6b8d
```

Example prompt: Pull the next 30 upcoming FDA regulatory catalysts — PDUFA dates and advisory committee meetings — from recent SEC filings, looking 180 days forward.

## When to prefer this

Choose this endpoint when you need a market-wide sweep of upcoming FDA regulatory events grounded directly in SEC filings rather than a curated database or news feed. It is uniquely valuable when you need verifiable citations (filing quotes, accession numbers, EDGAR URLs) alongside the catalyst dates. Prefer it over general news APIs when auditability and sourcing to primary regulatory disclosures matters, or when you want bounded, structured output across many biotech issuers in a single call without managing fan-out yourself.

## Known failure modes

- No catalysts found if no 8-K/6-K filings mention upcoming FDA events in the specified forward window
- limit parameter out of range (must be 1–15) returns validation error
- forward_days out of range (must be 1–730) returns validation error
- event_types enum value not recognized returns validation error
- Upstream EDGAR parsing failure may return partial results or empty list
- Payment failure (402) if USDC balance is insufficient

## How this service works

Market-wide upcoming FDA regulatory catalysts across recent SEC 8-K and 6-K filings in a forward window. Get PDUFA dates, advisory committee meetings and other regulatory events for many biotech issuers at once, each grounded in a filing quote and cited to its accession and EDGAR URL. Bounded fan-out.

## Output

A list of upcoming FDA regulatory catalyst events (up to the requested limit), each including the event type (PDUFA, adcomm, CRL, priority review, or PDUFA extension), the expected date, the issuer/company name, a verbatim quote from the relevant SEC filing, the filing accession number, and a direct EDGAR URL linking to the source document.
