How this service works
We listed 18 articles on the Coinbase x402 Bazaar but every one showed $0.00 — because we emitted maxAmountRequired (v2) while the marketplace reads amount (v1). Fixed in four lines.
Output
A markdown-formatted technical article explaining the root cause of the x402 Bazaar amount field mismatch (v1 `amount` vs v2 `maxAmountRequired`), with a four-line code fix that corrects all 18 listed endpoints showing $0.00.
