The article describes a four-line fix to resolve the issue.\n\nThe endpoint is associated with Ethereum address 0x1C1Ee78b938Af5333D3a99BF659e9aa771d8A8D5 and is designed to use the x402 payment protocol. However, during probing the endpoint returned HTTP 403 on POST and 401 on GET — it did not return the expected 402 Payment Required challenge. This means the x402 paywall may not be functioning correctly at the time of probing, or the endpoint may require additional authentication or routing not captured by the probe.\n\nThe hosting platform, Every Good Work, describes itself as a creator-focused content delivery service where 100% of each sale goes directly to the creator's wallet. Creators prepay credits for infrastructure, with hosting costs tiered by previous month's sales. No OpenAPI schema, pricing details, or API documentation were found at the origin. The article's actual price and payment token are unknown since no 402 challenge was captured.","tags":[],"capabilities":["x402-paywall","paid-article","content-delivery","ethereum-wallet-auth","creator-monetization"],"categories":["content","knowledge"],"synonyms":["x402 bazaar fix","coinbase x402 amount field","maxAmountRequired vs amount","x402 v1 v2 mismatch","paid article blockchain","every good work content"],"warnings":["Endpoint did not return HTTP 402 on GET or POST — x402 paywall may not be functioning or may require different routing","No OpenAPI schema or API documentation found at the origin","Price and payment token are unknown — no 402 challenge was captured","Docs, API, pricing, and README paths all return 404 at the origin"],"endpointUrl":"https://codex.everygoodwork.io/0x1C1Ee78b938Af5333D3a99BF659e9aa771d8A8D5/coinbase-x402-bazaar-amount-field-mismatch-eighteen-endpoints-free-four-line-fix","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1C1Ee78b938Af5333D3a99BF659e9aa771d8A8D5","amount":"10000","scheme":"exact","network":"eip155:8453","mimeType":"text/markdown; charset=utf-8","description":"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).
