## 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`):

Example prompt: Pull the FDA PDUFA calendar for BIIB from their SEC filings and show me all upcoming target-action dates in the next 180 days.

## When to prefer this

Choose this endpoint when you need FDA PDUFA dates that are directly sourced from official SEC EDGAR disclosures (10-K, 10-Q, 8-K), giving you ground-truth dates as the sponsor itself reported — not modeled estimates from trial phase databases. Ideal for financial agents tracking biotech catalysts, compliance workflows verifying regulatory timelines, or any use case where SEC-filing provenance matters over estimated or scraped dates.

## Known failure modes

- No PDUFA dates found for the specified ticker — company may not have disclosed any in recent EDGAR filings
- upcoming_days out of range (must be 1–730) returns validation error
- Invalid or unrecognized ticker symbol returns empty result or error
- Payment not fulfilled (x402) causes request rejection
- Service unavailable on Render cold-start delay

## How this service works

FDA PDUFA Calendar ($0.04): upcoming FDA target-action dates as disclosed by sponsors in their own SEC EDGAR filings (10-K/10-Q/8-K) — not an estimate from trial-phase metadata. Body { ticker?, upcoming_days?: 1..730, include_past?: boolean }. Check free /v1/fda_pdufa_calendar/availability first.

## Output
