HTTP 402 Payment Required

The request cannot proceed because payment or quota requirements are not satisfied; the status is reserved for future use by HTTP semantics.

Use 402 only when your API documents a product-specific billing or quota contract; HTTP does not define one universal payment workflow.

Use 402 only when your API documents a product-specific billing or quota contract; HTTP does not define one universal payment workflow.

Common mistakes

Building a payment flow on 402 as if HTTP defined its semantics; it is reserved.
