Resolves the ticker to its Ondo token, then runs the same group/proposal flow as `POST /api/v1/spot/proposals`. Leader/admin only. ## OpenAPI ````yaml /openapi.json post /api/v1/spot/stocks/proposals openapi: 3.1.0 info: title: Murmo API version: 1.0.0 description: >- REST API for the Murmo trading platform. Spot swaps, prediction markets, perpetual futures, social copy-trading groups, portfolio, and chat — everything a bot or AI agent needs to trade on Solana with a single API key. **The money contract:** every monetary value on the wire is a full-precision plain decimal **string** (e.g. `"12.50"`), never a number, never raw base units, never scientific notation, never rounded. Send money the same way. See the *Money & precision* guide. **Auth:** send `Authorization: Bearer murmo_...` on every request.
