Key Components an AI Trading API Must Provide

An AI trading API should include a normalized market data feed, granular permissioned keys, owner‑signed risk limits, clear status and error reporting, and an emergency stop mechanism. These components together enable an autonomous agent to act safely while preserving the ability to audit every action. Without them, developers face hidden risks and ambiguous failure modes.

What market data does an AI trading API need?

The API must expose price, volume, and order‑book snapshots together with the data source, timestamp, and freshness indicator. Any missing or unverified monetary value should be flagged rather than silently treated as zero. This transparency lets the AI model assess data quality and avoid decisions based on stale or incomplete information. In practice, the feed should also include a warning flag when a venue reports connectivity issues, allowing the agent to pause or switch to a backup source.

How are permissions and keys structured?

Funds are controlled by an owner key, while agent keys receive narrower scopes defined by the owner. Scopes can limit which venues, instruments, or order types the agent may use, and they can enforce daily notional or loss caps. A trade‑scoped agent key cannot withdraw funds; withdrawals require a separate owner‑signed intent, reducing the attack surface. The separation also means that if an agent key is compromised, the attacker can only place trades within the predefined limits and cannot move capital out of the account.

Which risk controls should be enforced by the API?

• ·Owner‑signed limits on maximum order size, daily notional, and daily loss.
• ·Expiry timestamps on orders to prevent lingering stale requests.
• ·Policy fields that can be updated without redeploying the agent.
• ·Explicit rejection codes when a limit is breached.

These controls are documented in the official API reference and can be adjusted via the owner’s signed policy updates. They do not guarantee profit and can still be overridden by a malicious owner, so developers must assume that loss is possible. Regular audits of the policy file help ensure that limits remain aligned with the overall risk appetite of the strategy.

How does the API report status and errors?

A durable mutation identity accompanies every order request, allowing the client to match responses with the original intent even if network timeouts occur. The API returns explicit error states rather than generic failures, enabling deterministic handling in the agent’s logic. Reconciliation processes must compare mutation IDs with on‑chain or venue confirmations to confirm execution. When an error indicates a temporary venue outage, the agent can implement a back‑off strategy instead of aborting the entire workflow.

What happens when an emergency stop is triggered?

Activating the emergency stop revokes the calling agent key, preventing further order submissions. It does not automatically close existing positions or cancel token allowances; those actions require separate owner review. This design limits unintended liquidations while still giving the owner a path to intervene. After the stop is lifted, the owner can re‑issue a fresh agent key with updated scopes if the underlying issue has been resolved.
