How this service works
Aerodrome vAMM OZ/USDC addLiquidity calldata, with the ERC-20 approve steps for BOTH sides prepended when the live allowance is short. POST /v1/tx/lp/aero/add { owner, ozAmount, usdcAmount, slippagePct? }. UNITS: ozAmount and usdcAmount are HUMAN DECIMAL STRINGS (e.g. "1133780" OZ, "0.75" USDC), NOT atomic - the LP routes are the exception on this API, every other builder takes atomic. Full details: GET /v1.
Output
An ordered array of transaction steps (to, data, value) ready to sign and submit on Base — typically one or two ERC-20 approve calls (OZ and USDC) when allowances are insufficient, followed by the Aerodrome addLiquidity calldata — plus the network identifier confirming Base chain.
Example use cases
First-time LP deposit with approvals
“I want to add liquidity to the Aerodrome OZ/USDC pool for the first time — my wallet is 0xAbC123, I want to deposit 500000 OZ and 0.40 USDC, and I've never approved either token so I'll need the approve steps too. Use 1% slippage.”
Rebalancing LP position after price move
“Help me top up my Aerodrome OZ/USDC liquidity position — owner is 0xDef456, I want to add another 250000 OZ and 0.20 USDC with 0.3% slippage. My USDC allowance should already be set but OZ might need an approve.”
Bot automating recurring liquidity adds
“I'm running an automated strategy that adds OZ/USDC liquidity on Aerodrome every week — generate the calldata steps for owner 0xGhi789, depositing 2000000 OZ and 1.50 USDC with 0.5% slippage so my bot can sign and broadcast them.”
Technical details
Endpoint
POSThttps://ozmium.org/v1/tx/lp/aero/addWhen to prefer
Use this endpoint when an agent needs ready-to-sign Aerodrome vAMM OZ/USDC liquidity-add calldata on Base, especially when ERC-20 allowances may be missing — it handles both approve steps and the LP deposit in a single call. Prefer it over generic Aerodrome SDKs when working within the Ozmium ecosystem and using human-readable decimal amounts rather than atomic units.
Side effects
- Invalid or missing owner address returns a 4xx error
- ozAmount or usdcAmount provided as atomic integers instead of human decimal strings causes incorrect encoding
- Slippage too tight against live pool price results in likely on-chain revert
- Aerodrome pool contract unavailable or paused on Base causes calldata generation failure
- Allowance check fails if the RPC node is degraded, potentially returning incomplete steps
