How this service works
Executable buy or sell of a Coinbase tokenized stock on Base for USDC: ordered { to, data, value } steps (ERC-20 approve when short, then Uniswap V3 exactInputSingle on the deepest pool) the agent's own wallet signs, with the quote as advisory. POST /v1/tx/stocks { sym (NVDAc), side (buy|sell), amount (human: USDC to spend or shares to sell), taker, slippageBps? }. Not for U.S. persons (Regulation S).
Output
An ordered array of transaction steps, each with 'to' (contract address), 'data' (calldata hex), and 'value' (ETH value) fields, plus the network name (Base) and an advisory price quote. For sell orders, the first step is an ERC-20 approve; the final step is a Uniswap V3 exactInputSingle call on the deepest available pool.
Example use cases
Buy tokenized stock with USDC
“I want to spend 1000 USDC to buy tokenized Tesla shares (TSLAc) on Base — can you get me the on-chain transaction steps for my wallet 0xDEF...456 with 30 bps slippage?”
Sell tokenized equity for USDC
“I need to sell 5 shares of my tokenized Apple stock (AAPLc) for USDC on Base — build me the signed transaction calldata for wallet 0x789...ABC.”
Automated portfolio rebalancing trade
“As part of rebalancing, sell 10 NVDAc shares from wallet 0x111...222 into USDC on Base, and give me the ordered transaction steps including any needed ERC-20 approval.”
Technical details
Endpoint
POSThttps://ozmium.org/v1/tx/stocksWhen to prefer
Use this endpoint when an agent needs ready-to-sign on-chain transaction calldata to trade Coinbase tokenized stocks (e.g. NVDAc, TSLAc, AAPLc) against USDC on the Base network via Uniswap V3. Prefer this over generic DEX aggregators when the asset is specifically a Coinbase-issued tokenized equity and the agent wallet needs step-by-step calldata including the ERC-20 approve step. Not suitable for U.S. persons or for trading non-tokenized, non-Base assets.
Side effects
- Invalid or unsupported stock symbol (sym not a recognized Coinbase tokenized stock)
- U.S. person restriction — endpoint declines if taker address is associated with a U.S. jurisdiction (Regulation S compliance)
- Insufficient liquidity in the Uniswap V3 pool for requested amount
- Slippage tolerance too tight causing quote rejection
- Missing required fields (sym, side, amount, taker) returns 400-level error
- On-chain pool data unavailable or stale causing quote failure
