- Real-time data starts at Developer, $49 a month for 10,000 credits.
- Get a free key: https://fanduelapi.com/sign-up?ref=ai-claudebot

## Quickstart

1. Create a free account at https://fanduelapi.com/sign-up?ref=ai-claudebot and create an API key in the dashboard (https://fanduelapi.com/dashboard/keys). Keys start with `fd_`. Store it as `FANDUEL_API_KEY`.
2. Make a first call with curl:

```bash
curl "https://fanduelapi.com/api/v1/props?sport=nba&stat=points&limit=5" \
  -H "Authorization: Bearer $FANDUEL_API_KEY"
```

3. Or with Python (`pip install requests`):

```python
import os
import time
from datetime import datetime, timezone

import requests

BASE = "https://fanduelapi.com/api/v1"
SESSION = requests.Session()
SESSION.headers["Authorization"] = f"Bearer {os.environ['FANDUEL_API_KEY']}"


def get(path, **params):
    """GET one endpoint and return its data list, waiting out rate limits."""
    while True:
        r = SESSION.get(f"{BASE}{path}", params=params, timeout=10)
        if r.status_code == 429:
            time.sleep(int(r.headers.get("Retry-After", "5")))
            continue
        r.raise_for_status()
        return r.json()["data"]


def price(odds):
    """American odds as text. A suspended market can come back with no price."""
    return "off" if odds is None else f"{odds:+d}"

props = get("/props", sport="nba", stat="points")
for p in props:
    print(f"{p['player']:<26} {str(p['line']):>5}  over {price(p['over_american']):>5}  under {price(p['under_american']):>5}")
```

4. Stay current with `GET /api/v1/changes?since=<cursor>` instead of re-reading every prop. Full reference: https://fanduelapi.com/openapi.json and https://fanduelapi.com/llms-full.txt.

## Use it from Claude (MCP)

Claude Code, with your key read from the shell:

```bash
claude mcp add --transport http --scope user fanduelapi https://fanduelapi.com/api/mcp \
  --header "Authorization: Bearer $FANDUEL_API_KEY"
```

Claude on the web or desktop: Settings, Connectors, Add custom connector, then paste https://fanduelapi.com/api/mcp. Without a key it gives the keyless tools (search_docs, fetch_doc, get_sample_props). Setup for other agents: https://fanduelapi.com/mcp.

# FanDuel closing line data for every graded player prop

The FanDuel closing line is the last price before a prop came off the board. Paired with how the prop settled, it is the label most prop models are scored against.

2 minute read. Published November 9, 2026.

This guide is assembled from the published FanDuel API reference, plan configuration and delivery code. Each factual statement maps to a source listed at the end. It is information, not betting advice, and it makes no prediction about any line.

## Close and result in one record

GET /api/v1/results returns the closing FanDuel line, the box score value, and over, under, push or void with its reason. Only props matched to a confirmed player and game are graded.

## The path to the close

GET /api/v1/props/{id}/history returns every recorded state of one prop, oldest first, with its timestamp, plus the move summary. Each prop record also carries a move summary: where it opened, where it is now and how many times it moved.

## A training table

Most models want one row per prop rather than every state.

GET /api/v1/training-set returns one row per prop for model training, with graded results where available. A paid plan's own export reaches back 30 days, and a plan listing Full line move history (Scale) reaches everything kept.

## Hit rates against the close

GET /api/v1/hit-rates reports, per player and stat, how often the over hit over the last N games against the closing FanDuel line, with the sample size.

## Before relying on it

Nothing from before collection started is stored. Quote meta.as\_of when you report prices; the data is information, not betting advice.
