Sentinel Values

TheRundown API uses specific sentinel values to communicate special states within odds and line data. These values are intentional and must be handled explicitly in your application.

Off the Board: 0.0001

A price or line value of 0.0001 means the market is off the board — the sportsbook has temporarily removed this line from availability.

This is not an error. It is a valid and expected state in the API response.

Common Reasons

• Pending injury news — a key player’s status is uncertain and the book is waiting for confirmation.
• Line adjustment — the sportsbook is recalculating the line due to sharp action or new information.
• Approaching game time — some books pull lines close to tip-off, kickoff, or first pitch.
• Regulatory or operational holds — the book may temporarily suspend the market for internal reasons.

Best Practices

• Display the line as “Off Board”, “N/A”, or hide it from the UI entirely.
• Do not show 0.0001 to end users.
• Do not treat 0.0001 as an actual price or use it in calculations (e.g., implied probability, expected value).
• Continue polling the API — the line may return to a valid price once the sportsbook re-posts it.

Example

In a V2 market response, a sentinel value appears in the price field of a price object:

{
  "19": {
    "price": 0.0001,
    "is_main_line": true,
    "updated_at": "2026-02-12T18:30:00Z"
  }
}

In this example, DraftKings (affiliate ID 19) has taken the line off the board. Your application should display this as unavailable rather than showing the raw value.

In a V1 response, the sentinel appears in moneyline, spread, or total fields:

{
  "moneyline": {
    "moneyline_away": 0.0001,
    "moneyline_home": 0.0001
  }
}
