Answer · American odds

Pinnacle odds API — American format

Updated 9 November 2026 · PinnFeed · 1 min read

Answer: each outcome object carries american (integer, as published), decimal, fair and fairProb. You do not choose a format query param — all are present on REST and WebSocket frames. Conversion rules match the schema.

Example outcome#

{
  "name": "home",
  "american": -105,
  "decimal": 1.9524,
  "fair": 2.0,
  "fairProb": 0.5
}

Conversion (reference)#

american > 0:  decimal = 1 + american / 100
american < 0:  decimal = 1 + 100 / |american|

Prefer fair for model work (margin removed). Keep american when you display US lines or compare to US sportsbooks.

Questions people ask#

Can I request only American odds?#

No separate format flag — ignore fields you do not need. Payload size is dominated by market count, not the extra number.

Positive and negative moneylines?#

Positive american is underdog style; negative is favorite style. Both appear on the same schema.
