{"ok":true,"host":"hello-world-x402.vercel.app","status":"ready","manifest":{"positioning":"This host serves developers and agents who need to validate x402 micropayment integration on Base mainnet using USDC. It provides three minimal endpoints: a plain-text hello-world response, a static JSON greeting with timestamp, and a payload echo that returns submitted JSON verbatim with a server timestamp. None of the endpoints perform computation or serve dynamic data; their sole purpose is payment-flow verification and round-trip testing.","host_overview":"hello-world-x402.vercel.app is a demonstration host that exposes three paywalled endpoints, each requiring an exact 1000-unit USDC payment on Base (eip155:8453) via the x402 protocol. All three endpoints return static or echoed content and are designed exclusively for testing and validating x402 payment flows, not for production data retrieval or computation.","routing_guidance":"Use this host exclusively for testing and demonstrating x402 micropayment flows on Base mainnet with USDC. It is the right choice when an agent or developer needs to confirm that payment authorization, settlement, and endpoint response work end-to-end in a low-stakes environment. Do not use this host for any production use case, data lookup, personalization, computation, or non-Base chain testing — all responses are static or echoed. For actual data APIs gated by x402, route to hosts that expose domain-specific skills (e.g., price feeds, analytics, or content endpoints). This host also does not support streaming, polling, or non-USDC payment methods.","capability_clusters":[{"skill_names":["fetch-hello-world","fetch-personalized-greeting"],"cluster_name":"Static Response Payment Testing","cluster_summary":"Endpoints that return fixed, non-personalized content after a USDC micropayment, useful for confirming that the x402 payment gate on Base accepts payment and returns a successful response."},{"skill_names":["echo-payload-verbatim"],"cluster_name":"Payload Echo and Integrity Verification","cluster_summary":"Accepts a caller-supplied JSON body and returns it verbatim alongside a server timestamp, enabling agents to verify round-trip payload integrity through a paywalled endpoint."}],"cross_skill_workflows":[{"steps":[{"skill_name":"fetch-hello-world","description":"Confirm the simplest possible x402 payment succeeds and returns a non-error response on Base."},{"skill_name":"fetch-personalized-greeting","description":"Confirm a JSON-structured paywalled response is returned correctly with timestamp and version fields after payment."},{"skill_name":"echo-payload-verbatim","description":"Submit a known JSON payload and verify it is returned byte-for-byte with a server timestamp, confirming full round-trip payload integrity through the payment gate."}],"when_to_use":"Use when an agent needs to validate the full x402 payment stack on Base in increasing complexity — from a bare response, to a structured JSON response, to a round-trip payload echo — before integrating with a production paywalled API.","workflow_name":"Progressive x402 Integration Smoke Test"}]},"model":"claude-sonnet-4-6","version_no":4,"generated_at":"2026-05-20T08:13:38.179Z","provenance":"ai_authored_unreviewed","ai_authored":true,"merchant_reviewed":false,"merchant_edited":false,"merchant_reviewed_at":null,"merchant_edited_at":null,"skill_md_url":"https://x402gle.com/servers/hello-world-x402.vercel.app/SKILL.md","skills_url":"https://x402gle.com/servers/hello-world-x402.vercel.app/skills.json"}
