What to compare
A price feed, chart integration and order-entry API serve different purposes. Ask which API is available to your account, whether it supports a demo, the authentication method, rate limits, supported orders and recovery after a lost connection.
Where headline claims fall short
An API can place unintended duplicate orders if a request times out. A useful evaluation includes idempotency, order-status reconciliation and a kill switch. API subscriptions, exchange data and server costs belong in the comparison alongside commission.
