Access WNBA projected starting lineups and per-player DFS stat projections from RotoGrinders, including fantasy points, ownership %, salary, and game context.
What is the RotoGrinders API?
The RotoGrinders API provides WNBA daily fantasy data across 2 endpoints, covering projected starting lineups and per-player stat projections. The get_player_projections endpoint returns over a dozen fields per player — including projected minutes, fantasy points, floor/ceiling, ownership percentage, and combo stats — while get_projected_lineups maps each player to their game context, DFS salary, and lineup status for a given slate.

Returns projected starting lineups for upcoming WNBA games. Each entry includes the player name, team, position, lineup status, salary, and game context (opponent, schedule ID). Data is sourced from RotoGrinders' free preview of their WNBA projections page. Results vary by DFS site due to different salary structures. Returns players for today's scheduled games.

}About the RotoGrinders API
Projected Starting Lineups
The get_projected_lineups endpoint returns a list of players expected to start for upcoming WNBA games. Each entry in the lineups array includes the player's name, team, position, status, salary, and opponent. A parallel games array lists each scheduled game with its schedule_id and participating teams, letting you join lineup data to specific matchups. The optional site parameter controls which DFS platform's salary scale is used — useful when building slates for different contests.
Per-Player Stat Projections
The get_player_projections endpoint returns a detailed projection object for each player on a given WNBA slate. The projections array includes standard counting stats (points, rebounds, assists, steals, blocks, turnovers, three-pointers), projected minutes, fantasy points (FPTS), value expressed as FPTS-per-dollar, a floor and ceiling range, projected ownership percentage, and combo stats such as PRA (points-rebounds-assists) and PA (points-assists). Like the lineups endpoint, the site parameter determines which scoring system and salary scale the FPTS and value fields reflect.
Date Context and Slate Coverage
Both endpoints return a date_info field containing the page title with date context, so you can confirm which slate the data corresponds to. The player_count field gives a quick count of returned players without requiring you to iterate the full array. Data reflects the free-preview tier of RotoGrinders' WNBA projections page, meaning coverage is limited to what that preview exposes on a given day.
The RotoGrinders API is a managed, monitored endpoint for rotogrinders.com — not a raw scraper you maintain. Every endpoint is automatically health-checked on a schedule, and when rotogrinders.com changes and a check fails, the API is automatically queued for repair and re-verified. It is built to keep working as the site underneath it changes.
This isn't an official rotogrinders.com API — it's an independent, maintained REST wrapper over public data. Where the source has no official API (or only a limited one), Parse gives you a stable contract over a source that never promised one, and keeps it current. Need a new endpoint or field? You can revise it yourself in plain English and the agent rebuilds it against the live site in minutes — contributing the change back to the shared API is free.
Will this API break when the source site changes?+

Can I fix or extend this API myself if I need a new endpoint or field?+
What happens if I call an endpoint that has an issue?+
- Identify projected starters and their DFS salaries to build WNBA lineups on FanDuel or DraftKings
- Filter players by projected ownership percentage to find low-owned GPP tournament targets
- Compare floor and ceiling projections to differentiate cash-game from tournament roster construction
- Calculate value plays using the FPTS-per-dollar field against salary constraints
- Track lineup status changes for late-swap decisions before a WNBA slate locks
- Join lineup status from get_projected_lineups with stat projections from get_player_projections for a combined player view
- Aggregate combo stats (PRA, PA) to target players in favorable matchups for specific DFS scoring formats
| Tier | Price | Credits/month | Rate limit |
|---|---|---|---|
| Free | $0/mo | 200 | 5 req/min |
| Hobby | $30/mo | 1,000 | 20 req/min |
| Developer | $100/mo | 5,000 | 100 req/min |
| Team | $300/mo | 20,000 | 300 req/min |
| Company | $1,000/mo | 100,000 | 500 req/min |
Each endpoint has a fixed posted price per successful call — most fall between 1 and 10 credits — shown on this API's page before you run it. Exceeding the rate limit returns a 429 response. Authenticate with the X-API-Key header.
Does RotoGrinders have an official developer API?+
What does the `site` parameter do, and which DFS platforms are supported?+
site parameter on both endpoints controls which DFS platform's salary scale and scoring system is used to calculate the salary, FPTS, and value fields. Supported platforms correspond to the DFS sites RotoGrinders covers in their WNBA projections preview. Omitting the parameter returns a default platform's values.
