{"id":"72188f4e-c920-42cd-8617-9dcf095715b2","shortId":"y5q6Be","kind":"x402","title":"Pay-per-access video file (MP4) served via x402 on Pinata/IPFS for 0.01 USDC on Base Sepolia.","tagline":"Pay-per-access video file (MP4) served via x402 on Pinata/IPFS for 0.01 USDC on Base Sepolia.","description":"This x402-enabled endpoint serves a specific IPFS-pinned video file (MP4) gated behind a micropayment of 0.01 USDC on the Base Sepolia testnet. The content is identified by its IPFS CID (`bafkreifmx3xajsrbfpzsrq2bbmwznnbkcnicuzdydi6yixuubd3c325x2e`) and is hosted on a Pinata-based gateway (`grapevine.dev-mypinata.cloud`). To access the file, a caller must include a valid `x-payment` header conforming to the x402 protocol (version 1, \"exact\" scheme).\n\nThe payment is routed to address `0x9F137a6134B62437813E4eF88bac89f6Cb408511` using the USDC token contract at `0x036CbD53842c5426634e7929541eC2318f3dCF7e` on Base Sepolia. The maximum amount required is 10,000 units (0.01 USDC with 6 decimals), and the payment timeout is 60 seconds. Upon successful payment verification, the endpoint returns the video content directly as `video/mp4`.\n\nThis appears to be a demonstration or early-stage deployment of pay-per-content delivery over IPFS using the x402 protocol. Documentation, OpenAPI specs, and additional context about the provider (\"Grapevine\") are not available — the crawled pages all return error messages. The endpoint itself is live and responds with a well-formed 402 challenge.","tags":[],"capabilities":["x402-payment-gating","ipfs-content-delivery","video-mp4-serving","base-sepolia-testnet","usdc-micropayment","pinata-gateway"],"categories":["storage","media"],"synonyms":["IPFS paid content","pay-per-view video","x402 video gateway","Pinata paywall","micropayment video access","IPFS CID paywall","grapevine pinata"],"warnings":["No documentation or OpenAPI spec available — all crawled pages return errors","Uses Base Sepolia testnet, not mainnet — payments use testnet USDC with no real monetary value","Single-CID endpoint: serves exactly one file, not a general-purpose API","Provider identity ('Grapevine') is unclear with no discoverable information"],"endpointUrl":"https://grapevine.dev-mypinata.cloud/x402/cid/bafkreifmx3xajsrbfpzsrq2bbmwznnbkcnicuzdydi6yixuubd3c325x2e","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x9F137a6134B62437813E4eF88bac89f6Cb408511","scheme":"exact","network":"base-sepolia","mimeType":"video/mp4","resource":"https://grapevine.dev-mypinata.cloud/x402/cid/bafkreifmx3xajsrbfpzsrq2bbmwznnbkcnicuzdydi6yixuubd3c325x2e","description":"0.01 USDC on base-sepolia","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"10000","maxTimeoutSeconds":60}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live and returns a well-formed x402 challenge with clear payment parameters and MIME type.
