Users now pay only for the AI compute they actually use on Coinbase's x402

Developers using Coinbase's x402 will now pay only for the AI compute resources they actually consume. The platform previously imposed a flat fee for all compute requests, regardless of task complexity, leading to overcharging for simple jobs and underpricing for intensive ones. That uniform cost structure masked the true resource burden of each request. Now, with the introduction of the 'Upto' feature, users can set a maximum spending limit before initiating a task. The system executes the request and charges based only on actual usage, not a predetermined flat rate. This shift aligns costs with real computational demand. Users gain finer control over spending, while the pricing model better reflects the underlying cost of delivering AI compute. The change improves cost efficiency for developers and corrects a misalignment between effort and expense that characterized the prior system. Under the new model, developers on x402 will face costs that reflect real usage, improving cost efficiency and pricing accuracy.
