# Exchange API

All trading operations go through a single endpoint:

```
POST /api/v1/exchange
```

The `action.type` field determines which operation to execute. Every request requires an EIP-712 signature. See [Authentication](/api-reference/signing.md) for signing details.

JavaScript snippets in this section are illustrative pseudocode for action shape and flow. The official high-level SDK examples are currently provided by the Python SDK.

{% hint style="warning" %}
Vault operations can affect vault balances, ownership, withdrawal flow, or lifecycle depending on the action. Do not treat a vault-authorized Agent as trading-only. Review [Agent Safety](/api-reference/agent-safety.md) before automating vault workflows.
{% endhint %}

## Python SDK Examples

The official SDK repository includes runnable examples for common Exchange actions:

* Orders: [place\_order.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/place_order.py), [place\_tp\_sl\_orders.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/place_tp_sl_orders.py), [replace\_order.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/replace_order.py), [place\_bracket\_order.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/place_bracket_order.py), [cancel\_order.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/cancel_order.py), [cancel\_all.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/cancel_all.py)
* Authorization: [faucet\_claim.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/faucet_claim.py), [approve\_agent.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/approve_agent.py), [revoke\_agent.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/revoke_agent.py)
* Account settings: [set\_leverage.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/set_leverage.py), [set\_margin\_mode.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/set_margin_mode.py), [assign\_pos\_margin.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/assign_pos_margin.py)
* Funds and vaults: [withdraw.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/withdraw.py), [vault\_deposit.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/vault_deposit.py), [vault\_withdraw.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/vault_withdraw.py), [bind\_referral.py](https://github.com/afx-dex/afx-python-sdk/blob/main/examples/exchange/bind_referral.py)

## Agent Revocation

Use `revoke_agent.py` or `client.exchange.revoke_agent(...)` to revoke the currently approved Agent wallet. The SDK submits an `approveAgent` action with the zero address and `validitySeconds=0`.

Revocation is a **Master wallet** operation. Keep it available in operational runbooks so automated trading access can be disabled quickly.
