## Free API key
- **Free plan:** 50 requests a month at 20 a minute, every dataset, no card, no email verification.
- **Sign up:** https://draftkingsapi.com/auth/sign-up?ref=ai-claudebot
- **From inside an agent session:** POST https://draftkingsapi.com/api/v1/agent/signup with JSON `{"data_wanted": "...", "use_case": "...", "ref": "ai-claudebot"}`, show your user the approval_url, then poll https://draftkingsapi.com/api/v1/agent/token with device_code. The key is returned once.
- **No key yet:** `curl --fail-with-body "https://draftkingsapi.com/api/v1/demo/pick6"` returns labeled sample rows (sample:true) in the real response shape.

## Quickstart

1. Create a free key at https://draftkingsapi.com/auth/sign-up?ref=ai-claudebot (no card) and export it: `export DRAFTKINGS_API_KEY=...`

2. Call the API with curl:

```bash
curl --max-time 30 --fail-with-body 'https://draftkingsapi.com/api/v1/pick6/history?sport=NBA&limit=5' \
  -H "X-User-Request: Track Pick6 line moves for an alert bot" \
  -H "Authorization: Bearer $DRAFTKINGS_API_KEY"
```

3. Or call it from Python:

```python
import os, requests

response = requests.get(
    "https://draftkingsapi.com/api/v1/pick6/history?sport=NBA&limit=5",
    headers={
        "Authorization": "Bearer " + os.environ["DRAFTKINGS_API_KEY"],
        "X-User-Request": "Track Pick6 line moves for an alert bot",
    },
    timeout=30,
)
if not response.ok:
    raise RuntimeError(f"API {response.status_code}: {response.text}")
print(response.json())
```

## Use it from Claude (MCP)

MCP server: https://draftkingsapi.com/api/mcp (Streamable HTTP). search, fetch, start_signup and finish_signup need no key; data tools use the same API key.

```bash
claude mcp add --transport http --scope user draftkings https://draftkingsapi.com/api/mcp --header "Authorization: Bearer $DRAFTKINGS_API_KEY"
```

Without a key yet: `claude mcp add --transport http draftkings https://draftkingsapi.com/api/mcp`, then call start_signup. Setup for other clients: https://draftkingsapi.com/agents.md.

Nullable multipliers are easy to corrupt with one default value. A null is a missing observation, and your schema and your interface should both be able to show that.

## Model the field as optional

Use a nullable numeric column, leave the display label in a column of its own, and never let a default fill the gap.

The standings_multiplier field is a nullable number on each selection, and formatted_standings_multiplier is a separate nullable label. Missing side, period and promo labels remain unknown.

## Keep one-sided rows one-sided

Do not synthesize the missing side to make a row look symmetrical.

Every explicit source selection is retained, even when one-sided. Market rows include alternatives and paused or live entries, not unique athletes or a complete board.

## Do not convert to odds

A number that resembles a price is not one.

Standings multipliers are not decimal odds or probabilities. DFS salaries and FPPG are not sportsbook lines. Independent service operated by DD Inc., not affiliated with or endorsed by DraftKings. No wagering: this service does not place, recommend or settle entries or bets.

## Show availability separately

Whether a value is present and whether a row is usable are separate questions.

Paused entries are explicitly marked and must not be treated as selectable. Stored rows are not a guarantee of current selectability. A live-stat clock is not the offer clock; source market update time is unknown.
