Apply for pro tierWhy we're free
- Every venue we ingest publishes free public endpoints (HL, Binance, Bybit, OKX, Deribit, CoinGecko, DefiLlama, Farside, bitcoin-data.com). Our infrastructure cost runs at single-digit dollars per day.
- The frontend, SDKs, and ingestion are MIT-licensed. You can vendor any of it.
- We don't have a user-management database to feed. Permissioned features are wallet-scoped.
- We trade through HL with builder routing. That model funds the upkeep on its own.
What might eventually carry a fee
- The 3,000 req/min ceiling is intentionally generous for most use cases; an enterprise tier above it could carry a fee.
- Protocols and HIP-3 deployers asking for branded versions of our widgets / dashboards.
- Specific data integrations from HL Labs / venues / market makers.
- No charging for what's already shipped, no retroactive paywalls.
