🟢list_stocks(chain, query)

Tokenized stocks listed on The River, with ticker, token symbol, issuer, chain and trade link. Filter by chain and/or a search query (ticker, symbol or name).

Input Schema

{
  "type": "object",
  "properties": {
    "chain": {
      "type": "string",
      "enum": [
        "base",
        "robinhood"

🟢trade_link(ticker, address, chain, side, usd, ...)

A pre-filled River trade link. A buy by ticker with usd (no address or chain) returns a best-price link that opens the cheapest issuer for the user. Give exactly one of usd (buy only, settlement stablecoin, up to 6 decimals) or qty (tokens, up to 18 decimals). The user reviews this on The River and signs in their own wallet; nothing happens until they do.
