Worked example — The Vorstand hit rate

German board buys hit 71% positive at 6-12 months

The role tag is the moat, not latency. Treat every PDMR row the same and you eat a 13% hit rate alongside 55%. By utilizing our normalized insider_role field to filter specifically for "Vorstand" (Board Members) buying their own stock, quants consistently isolate the true signal from the noise.

The Developer Experience

The API exposes two endpoints: /v1/filings for PDMR insider trades, and /v1/holdings for 5%+ shareholder crossings. Both support cursor + delta-since pagination.

1. Polling via REST

# All German insider trades from the last week
curl -H "Authorization: Bearer alt_live_..." \
  "https://api.altdataeu.com/v1/filings?country=DE&from=2026-04-29"

# Substantial holdings >= 5% in Swiss issuers
curl -H "Authorization: Bearer alt_live_..." \
  "https://api.altdataeu.com/v1/holdings?country=CH&min_pct=5"

2. Standardized JSON Response
