| Field | Type | Required | Description |
|---|---|---|---|
type | string | yes | Must be outcomeFills for /info. |
coin | string | no | Exact outcome coin, such as #30. Cannot be combined with outcomeId or side. |
outcomeId | number | no | Outcome ID. When supplied without side, returns both Yes and No side fills. |
side | string | no | yes, no, 0, or 1. Requires outcomeId. |

If you omit coin, outcomeId, and side, the method returns recent fills across all outcome coins.
Billing
Billed by returned fill objects
outcomeFills responses are billed by the number of fill objects returned, not as one response per HTTP request.
A response with 2,000 fills counts as 2,000 responses/API credits.
Requests that return an empty array are billed as 0 responses/API credits and do not count against usage. Error responses are not charged.

REST /info responses return an array directly. JSON-RPC responses return the same array under result. Empty matches return []; they are not errors.
