How this service works
Four live marketplace failures that break machine-paid API delivery. A field report from publishing the same x402 API across four agent marketplaces. It documents a validator 500 after a correct 402, a lost HTTP method, dropped buyer query input, and a proxy with no trustworthy origin proof, plus the acceptance tests that catch each failure before a buyer pays.
Output
The full text content of the article documenting four live x402 marketplace failures: a validator 500 after a correct 402, a lost HTTP method, dropped buyer query input, and a proxy with no trustworthy origin proof — including the acceptance tests designed to catch each failure before a buyer pays.
