When a GET request is made to the resource URL containing a specific CID (bafkreih55jnxbawbrgrkr4fmjducyp3ma27gcmhhdelhszatgcgdfxrpzm), the server returns an HTTP 402 challenge requiring payment of 0.5 USDC on the Base Sepolia testnet. Once a valid x-payment header is provided, the endpoint delivers the content as text/plain.\n\nThe x402 challenge specifies the \"exact\" payment scheme, accepting USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e) with a maximum timeout of 60 seconds. Payment is directed to address 0x99935f281d3ED1E804bF1413b76E0B03e1fed4F9. The gateway appears to be built on Pinata's IPFS infrastructure, acting as a pay-gated content delivery layer for pinned files.\n\nDocumentation is effectively absent — all non-CID paths return generic error messages. There is no OpenAPI spec, no robots.txt, and no agents.txt. The endpoint is live and responds correctly with a well-formed x402 challenge, but the lack of surrounding documentation limits confidence in the broader service capabilities beyond this single CID.","tags":[],"capabilities":["x402-paywall","ipfs-content-delivery","pinata-gateway","base-sepolia-usdc","text-plain-response","cid-based-routing"],"categories":["storage","crypto"],"synonyms":["IPFS gateway","paid IPFS access","Pinata paywall","x402 IPFS","content-addressed storage","pay-per-download","gated IPFS content","decentralized storage paywall"],"warnings":["No documentation found — all crawled paths return error messages","Runs on Base Sepolia testnet; not suitable for production payments","Only a single CID is referenced; unclear if the gateway supports arbitrary CIDs behind paywalls","No OpenAPI spec, agents.txt, or robots.txt available","Response content is unknown — mime type is text/plain but actual payload cannot be verified without payment"],"endpointUrl":"https://grapevine.dev-mypinata.cloud/x402/cid/bafkreih55jnxbawbrgrkr4fmjducyp3ma27gcmhhdelhszatgcgdfxrpzm","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x99935f281d3ED1E804bF1413b76E0B03e1fed4F9","scheme":"exact","network":"base-sepolia","mimeType":"text/plain","resource":"https://grapevine.dev-mypinata.cloud/x402/cid/bafkreih55jnxbawbrgrkr4fmjducyp3ma27gcmhhdelhszatgcgdfxrpzm","description":"0.5 USDC on base-sepolia","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"500000","maxTimeoutSeconds":60}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a well-formed x402 challenge, but there is zero documentation, no OpenAPI spec, no examples, and no information beyond what the 402 challenge itself provides.
