Authorizations

​
Authorization
string
header
required

Send your API key as Authorization: Bearer murmo_.... Keys are created in the Murmo app. Header-only — keys are never read from the query string. Valid for the REST API under /api/v1 only (not the GraphQL endpoint).

Path Parameters

​
id
string
required

Body

application/json

Send amountUsd (human USD string) OR max: true. When max is true, amountUsd is ignored.

​
amountUsd
string

A monetary amount as a full-precision plain decimal string in USD — never a number, never raw base units, never scientific notation, never rounded. Parse with a decimal library; round only for display.

Example:

"12.50"

​
max
boolean

Response

The executed buy trade.
