About Meridian

Meridian aggregates and analyzes data from congressional trades, institutional filings, dark pool activity, on-chain whale movements, and 15+ other signal sources to give you the clearest picture of what's moving markets.

Open & Transparent

Every data source we use is publicly disclosed — SEC filings, FINRA data, on-chain records, government databases. We don't manufacture signals; we aggregate, normalize, and surface what's already out there, presented clearly. Our API is documented via OpenAPI, our agent capabilities are published via agents.json, and our payment model follows the open HTTP 402 / x402 standard. No black boxes. No hidden edge.
