WebSocket Firehose

For systematic trading desks where sub-100ms latency separates alpha from noise. Our WebSocket firehose pushes structured JSON payloads the exact second a public tender clears or an insider filing publishes across 27 EU member states.

  • Event-driven publish-subscribe architecture.
  • Filter live streams by specific ISINs, LEIs, or jurisdictions.

REST API (Point-in-Time)

Query complete historical European regulatory records. Every record includes immutable published_at and revised_at timestamps to guarantee non-anticipatory backtesting with zero look-ahead bias.

Flat Files & Snowflake

Bypass API pagination entirely. We drop daily or weekly Parquet and CSV snapshots directly into your institutional AWS S3 or Google Cloud Storage buckets. Or query our datasets natively with zero data movement via the Snowflake Data Cloud.
