OpenAI’s API-credit benefit announced on 28 October 2026 covers built-in tools as well as model usage for eligible subscribers. Before assigning that balance to web research, estimate the search line separately. Credits change how a bill is funded; they do not make each tool call free.
A short API answer can still involve several web searches. Estimating its cost from the final paragraph alone misses work performed by tools and any search content billed under the selected tool and model.
Make the estimate match the workflow
The current OpenAI pricing page lists model tokens and built-in tools separately. Search pricing can depend on the tool variant and model. Read the relevant section rather than copying a rate from another search endpoint or an old example.
For a fictional ten-question research job, record how many requests and tool calls each question is allowed. Keep input, output and tool-related charges as separate estimate lines. Label every numerical rate with its source date; if a component is unknown, keep it unknown rather than treating it as free.
Compare the actual usage
After a permitted small run, inspect the returned usage and the correct project’s usage view. A source citation is not a receipt for exactly one search call. Check any retries and repeated searches before multiplying the result by ten. Keep the estimate as a planning aid, not a promise that a budget alert will stop the job or that every short answer is cheap.
As checked on 4 November 2026, standard built-in web search is listed at $10 per 1,000 calls, plus search-content tokens at the applicable model rate. Ten questions with two calls each would therefore produce a $0.20 tool-call line, before model input, output and search-content charges. This example is not the total job price; preview variants have different rules. Recheck the current table before spending.
The credit benefit requires an eligible paid Pro or Business subscription and a linked API organization under the documented ownership rules; it does not raise ChatGPT or signed-in Codex limits. When free credits run out, purchased balance can continue funding usage. Check the linked organization and remaining balance. No paid request was run for this example.
