An AI API integration wires a model from a provider such as OpenAI, Anthropic or Google into an existing product or system, adding one defined AI capability without building a new application.

E-commerce builds are shaped by the store platform. Most work connects to Shopify or a similar system, and has to handle catalogue data, orders and returns accurately during peak trading.

## What drives the cost

Work expected to take under a month has a median of $400, against $16,800 for over six months. Part of that gap is built in, because hourly estimates are calculated from expected length. Fixed-price posts state a median of $270, while hourly posts work out at $4,000 on our estimate: 15 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
