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.
A typical scope
- Server-side calls to the model provider
- Prompts and structured output handling
- Authentication and key management
- Rate limits, retries and fallbacks
- Usage tracking for cost control
Systems it usually connects to
- Shopify or WooCommerce

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.

|---|---|---|
| Under 1 month | $400 | 24 |
| 1 to 3 months | $3,100 | 72 |
| 3 to 6 months | $15,300 | 5 |
| Over 6 months | $16,800 | 11 |
