Projections API

Authentication

Include your API key in the X-API-Key header with every request. Requests without a valid key are rejected.

curl -H "X-API-Key: dk_live_your_key_here" \
  https://bluecollardfs.com/api/nfl_draftkings

Endpoints

All endpoints accept GET requests and return application/json.

Response Shape

Every endpoint returns a list of slates. Each slate includes metadata (type, start time, last update) and a player array with projections, salaries, and value metrics.

{
  "slates": [
    {
      "slate": "Main",
      "slate_type": "classic",
      "date": "02_26_26",
      "updated": "15:18:01 ET",
      "info": [
        {
          "name": "Player Name",
          "team": "NYK",
          "position": "PG",
          "opponent": "BOS",
          "projection": "42.5",
          "salary": "8200",
          "value": "5.2"
        }
      ]
    }
  ]
}

Code Examples

import requests

resp = requests.get(
    "https://bluecollardfs.com/api/nfl_draftkings",
    headers={"X-API-Key": "dk_live_your_key_here"}
)
slates = resp.json()["slates"]

for slate in slates:
    print(f"{slate['slate']} ({len(slate['info'])} players)")
    for p in slate["info"][:3]:
        print(f"  {p['name']} {p['position']} - {p['projection']} pts")

const resp = await fetch("https://bluecollardfs.com/api/nba_fanduel", {
  headers: { "X-API-Key": "dk_live_your_key_here" }
});
const { slates } = await resp.json();
console.log(slates.map(s => s.slate));

function getProjections() {
  var resp = UrlFetchApp.fetch(
    "https://bluecollardfs.com/api/nfl_fanduel",
    { headers: { "X-API-Key": "dk_live_your_key_here" } }
  );
  var slates = JSON.parse(resp.getContentText()).slates;
  // Write to spreadsheet...
}

Rate Limits & Errors

API keys include 200 requests per day across all endpoints. That's enough to pull every sport/site combination once per hour for a full day. Daily limits reset at midnight UTC.

Best Practices

• Use the updated field to check freshness before re-fetching.
• Cache responses for at least 5 minutes — projections don't change more frequently than that.
• Projections are typically available starting 2-3 hours before slate lock and update as game time approaches.
• Attribution is appreciated when BluecollarDFS data powers published insights or tools.

About BluecollarDFS

BluecollarDFS is a daily fantasy sports (DFS) projection and lineup optimization platform. We produce proprietary player projections for NFL, NBA, MLB, and PGA Tour golf across DraftKings, FanDuel, and Yahoo contest platforms.

Our projections power an in-browser lineup optimizer that builds salary-cap-compliant lineups using linear programming. Users configure stacking rules, exposure limits, and position constraints — the optimizer handles the math.

The Projections API gives developers and tools the same data programmatically. Whether you're building a custom model, feeding a Google Sheet, or integrating projections into an AI agent — the API provides structured, up-to-date projection data with a single authenticated request.
