The specific resource is identified by a CID (Content Identifier): bafkreie4ypoedvoijd4tvwbu6q22noku7stboykhkx5uwl742y36yjcg24. To access the content, a client must submit a valid x-payment header containing a payment proof for 0.1 USDC on the Base Sepolia testnet. The payment is made to address 0x9F137a6134B62437813E4eF88bac89f6Cb408511 using the USDC token contract at 0x036CbD53842c5426634e7929541eC2318f3dCF7e.\n\nThe gateway is operated by Grapevine (gateway.grapevine.fyi) and uses the x402 protocol version 1 with the \"exact\" payment scheme. The content is returned as application/octet-stream. The payment timeout is 60 seconds. No OpenAPI documentation, agents.txt, or additional docs were found on the gateway — all crawled paths returned error messages indicating invalid or missing CID parameters.\n\nBecause this runs on Base Sepolia (a testnet), the USDC involved is testnet USDC with no real monetary value. This makes the endpoint suitable for experimentation and development of x402-based payment flows rather than production content delivery.","tags":[],"capabilities":["x402-payment","ipfs-content-retrieval","base-sepolia-testnet","usdc-micropayment","content-gating","octet-stream-delivery"],"categories":["storage","crypto-payments"],"synonyms":["x402 paywall","IPFS gateway","pay-per-download","micropayment content","grapevine gateway","content-addressed storage","CID retrieval","crypto-gated content"],"warnings":["No documentation found at any crawled path — all return error messages","Content type is application/octet-stream with no description of what the content actually is","Runs on Base Sepolia testnet — USDC has no real value","No OpenAPI schema or response examples available","The specific CID content is unknown; cannot verify the endpoint delivers useful data"],"endpointUrl":"https://gateway.grapevine.fyi/x402/cid/bafkreie4ypoedvoijd4tvwbu6q22noku7stboykhkx5uwl742y36yjcg24","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x9F137a6134B62437813E4eF88bac89f6Cb408511","scheme":"exact","network":"base-sepolia","mimeType":"application/octet-stream","resource":"https://gateway.grapevine.fyi/x402/cid/bafkreie4ypoedvoijd4tvwbu6q22noku7stboykhkx5uwl742y36yjcg24","description":"0.1 USDC on base-sepolia","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"100000","maxTimeoutSeconds":60}]},"qualityScore":"0.250","qualityRationale":"Very sparse information available.
