The endpoint uses the x402 payment protocol (version 1) with the \"exact\" payment scheme, meaning the caller must attach an X-PAYMENT header with a valid payment proof before the resource will return its JSON response.\n\nThe hosting application at x402-poc.vercel.app is a proof-of-concept platform that lets users create x402-based tip links. Each link is a paywall-gated GET endpoint tied to a specific Ethereum address. The payment is routed to the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base. The maximum timeout for payment settlement is 300 seconds.\n\nDocumentation is minimal — the site offers only a landing page with a \"Create Tip Link\" flow and no API docs, pricing page, or README. The endpoint itself is live and returns a well-formed 402 challenge, but there is no information about what the successful response body contains beyond the declared mimeType of application/json.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","tip-jar","exact-scheme","evm-wallet-payment"],"categories":["payments","crypto"],"synonyms":["x402 tip","buy a coffee crypto","USDC tip link","Base network payment","micropayment endpoint","crypto tip jar","x402 coffee"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all return 404.","This is a proof-of-concept (x402-poc) deployment, not a production service.","Successful response body structure is unknown; only mimeType application/json is declared.","The endpoint is tied to a single hardcoded wallet address."],"endpointUrl":"https://x402-poc.vercel.app/api/0x0806D3920dAFd50e8cEb189c82D2d3a217e2A045/coffee","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x0806D3920dAFd50e8cEb189c82D2d3a217e2A045","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://x402-poc.vercel.app/api/0x0806D3920dAFd50e8cEb189c82D2d3a217e2A045/coffee","description":"buy 0x0806D3920dAFd50e8cEb189c82D2d3a217e2A045 a coffee.
