How this service works
Transfer a token (ERC-20) or native ETH to any recipient from the agent's own wallet- full parity with the app's Send. POST /v1/tx/send { to, amount (atomic: wei for ETH, token decimals otherwise), token? (omit / native sentinel = ETH) }. Returns { to, data, value } steps.
Output
Returns an array of transaction steps, each containing 'to' (target contract or recipient address), 'data' (calldata for the transaction), and 'value' (native ETH value in wei). For ERC-20 transfers there may be an approve step before the transfer step. These steps are ready to be signed and broadcast.
Example use cases
Example prompt
“Send 0.05 ETH to 0xAbC1234567890dEF1234567890abcdef12345678 from my agent wallet — give me the transaction steps to sign and submit.”
Technical details
Endpoint
POSThttps://ozmium.org/v1/tx/sendWhen to prefer
Use this endpoint when an AI agent needs to send native ETH or any ERC-20 token from its own self-custodied wallet to an arbitrary recipient on Base mainnet. Prefer this over swap endpoints when no asset conversion is needed — just a direct transfer. It provides full parity with Ozmium's app Send flow and handles both ETH and token transfers through a unified interface.
Side effects
- Invalid recipient address format — returns error or malformed calldata
- Amount exceeds wallet balance — transaction will revert on-chain
- Unknown or unsupported token contract address
- Missing required 'to' or 'amount' fields — request rejected
- Amount not in atomic units (e.g. human-readable decimals passed instead of wei) — incorrect transfer amount on-chain
- Payment for API call ($0.02 USDC x402) fails — request blocked
