Send a Transaction

Outline for the full guide:

• Building the request — chain_id, to, data, value, optional gas_limit.

• The Agent-pays gas model and how to top up.

• Reading the response — tx_id, tx_hash, status semantics.

• Polling vs. webhook for confirmation.

• Common errors: LIMIT_EXCEEDED, ADDRESS_BLOCKED, INSUFFICIENT_GAS.

• Worked example: ERC-20 transfer.

• Worked example: arbitrary contract call (e.g. NFT mint).

For now see the Direct API quickstart for a runnable example.
