- `stocktoken\_access\_checkout`: Build on-chain ETH payment plan for Pro/Team. After user pays, call stocktoken\_access\_activate.
- `stocktoken\_access\_activate`: After ETH payment to treasury is confirmed, verify and issue API key \(shown once\).
- `stocktoken\_access\_status`: Check paid access for current API key context or a wallet owner.
- `stocktoken\_list`: List canonical Stock Tokens, ETFs, USDG, and WETH on Robinhood Chain 4663. Use this before trusting any address. Do NOT use for US brokerage equities \(use Robinhood Trading MCP\). Only registry addresses are real tokenized stocks.
- `stocktoken\_get`: Get metadata for one canonical Stock Token or core asset by symbol \(e.g. NVDA\) or contract address on Robinhood Chain 4663. Use to verify a token is official before trading.
- `stocktoken\_price`: Read the Chainlink USD price and ERC-8056 uiMultiplier for one registry token on chain 4663. This is not a swap quote and not a brokerage quote. Use stocktoken\_quote when you need amountOut.

If none is executable, the result is oracle-indicative and is not a fill. Pro required. Does not sign or broadcast.

- `stocktoken\_execute\_plan`: Build an unsigned swap plan on chain 4663. Picks the executable venue with the higher amountOut \(v4, v3, 0x, or Uniswap API\). Steps are an ETH fee of about 10 bps, token approve, and the swap. v4 also adds a Permit2 approval. Does NOT sign or broadcast. Pro required. The user signs. A v4 plan expire

- `stocktoken\_liquidity\_matrix`: Liquidity matrix for major USDG pairs on chain 4663. each row reports hookless Uniswap v4 and on-chain v3. eitherExecutable true means at least one of those can fill the sample size.
