It serves protected JSON content behind an HTTP 402 paywall using the x402 protocol (version 1). To access the resource, a client must include a valid X-PAYMENT header satisfying the payment challenge.\n\nThe endpoint accepts payment via the \"exact\" scheme on the Base network. The required asset is USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maxAmountRequired of 100 (in the token's smallest unit). Payments are directed to address 0x32d19F868559AC212555B41C0Eb35FB2EECD7877, and the payment timeout is 300 seconds. The response MIME type is application/json.\n\nBecause this is described as a \"fullstack demo,\" the actual protected content is unknown and likely minimal or illustrative. No documentation, OpenAPI spec, or detailed description of the response payload is available. The site returns 404 for /docs, /api, /pricing, and /README. Treat this as a reference implementation of x402 rather than a production data service.","tags":[],"capabilities":["x402-paywall","usdc-payment","base-network","json-response","next-js-demo"],"categories":["payments","demo"],"synonyms":["x402 demo","402 payment required","paid API","USDC gated content","Base network paywall","HTTP 402","x-payment header"],"warnings":["Self-described as a 'fullstack demo' — not a production service","No documentation available (all doc/api/pricing/readme paths return 404)","Protected content payload is completely unknown","No information on refund, dispute, or uptime guarantees","maxAmountRequired is '100' but the unit denomination (wei-level or dollar-level) is ambiguous without further context"],"endpointUrl":"https://x402-next.netlify.app/protected","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x32d19F868559AC212555B41C0Eb35FB2EECD7877","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://x402-next.netlify.app/protected","description":"Access to protected content","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"100","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a well-formed x402 challenge, but there is no documentation, no OpenAPI schema, no description of the actual protected payload, and the site self-identifies as a demo.
