FAQ

How do I connect Diamond Projections to Gemini?
In Gemini, open Extensions → MCP servers → Add and paste https://diamonddfs.com/api/mcp. Sign in with your Diamond Projections account.
Is MCP support live in Gemini yet?
Native MCP-connector support inside Gemini consumer apps is not yet generally available from Google. In the meantime, you can use Diamond Projections directly via our REST API (https://diamonddfs.com/api/v1) from any Gemini app or Gemini-powered agent (Vertex AI, ADK, custom code).
Do I need an API key, or does OAuth work?
Both. Use OAuth 2.1 (PKCE) for end-user flows, or mint a long-lived API key (dp_live_…) at https://diamonddfs.com/settings/api-keys and pass it as Authorization: Bearer …. OAuth refresh tokens rotate; API keys do not.
What can I build with Diamond Projections + Gemini today?
Any Gemini agent that can make authenticated HTTP requests: ask it to fetch today's player pool, build an optimal DraftKings MLB lineup, swap a player, or explain a projection — all backed by /api/v1 endpoints documented at https://diamonddfs.com/api.
What is a slateId and do I need to pass one?
slateId is the DraftKings draft-group ID — the canonical slate selector. Call /api/v1/slates first, pick the slateId that matches the contest you're entering, and pass it to every downstream call. slateDate alone is ambiguous on multi-slate days.
Is there a free trial?
Yes — start at https://diamonddfs.com/signup. No credit card, no invite code.
Which sports does it cover?
DraftKings MLB DFS today; NFL and NBA on the roadmap.
What does it cost?
Free trial, then paid tiers for full player pool and unlimited optimizer / MCP usage. See https://diamonddfs.com for current pricing.
