Gemini Trust Company Rewards API
Endpoints for the Maker Rebate and Liquidity Rewards programs.- **Maker Rebate** — per-fill rebates earned by resting limit orders that get filled. Rates and rebate multipliers are configured per category. Public rate schedule plus authenticated payout and summary endpoints.- **Liquidity Rewards** — daily USD reward pools distributed across qualifying makers based on quote uptime, spread, and size. Public config + event listing, authenticated daily and lifetime summary endpoints.When a program is not active, its endpoints return `503 Service Unavailable`.**Note on field naming.** Response fields under the Rewards endpoints use `snake_case` (e.g. `event_ticker`, `daily_pool_usd`).
