}Authorizations
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
Body
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.
"12.50"
Response
The prediction trade (or a pending settling receipt).
