Gemini Trust Company

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`). This differs from the `camelCase` convention used by the rest of the Prediction Markets REST endpoints.
