When accessed without payment, it returns a 402 Payment Required challenge requesting 0.5 USDC on the Base network. Once a valid x-payment header is provided, the gateway returns the requested content as plain text.\n\nThe specific resource behind this endpoint is identified by the IPFS CID `bafybeif5ck7iuvkdq5n2a2hxxvbwaoade3p43pbyp2jhb355bg6yl7y3fa`. The payment is made to address `0x5ba9355a10611Ed4339526472a59bEfed3549bAD` using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The x402 challenge uses the \"exact\" payment scheme with a maximum timeout of 60 seconds.\n\nDocumentation for this gateway is sparse. The root domain returns an error indicating a CID is required, and no docs, API reference, or pricing pages were found. The gateway appears to be a general-purpose paid IPFS content retrieval service, but details about what content is behind this particular CID, rate limits, or additional features are not available from the crawled material.","tags":[],"capabilities":["ipfs-content-retrieval","x402-payment","base-network","usdc-payment","cid-addressed-content","text-plain-response"],"categories":["storage","crypto-payments"],"synonyms":["IPFS gateway","paid IPFS","content-addressed storage","Grapevine gateway","x402 IPFS","decentralized content retrieval","CID gateway","Base USDC payment"],"warnings":["No documentation found — all crawled pages return errors","Content behind this CID is unknown; the response MIME type is text/plain but actual content is unverified","No OpenAPI or schema documentation available","Cost is 0.5 USDC per request which is relatively high for a single fetch — verify value before purchasing"],"endpointUrl":"https://gateway.grapevine.fyi/x402/cid/bafybeif5ck7iuvkdq5n2a2hxxvbwaoade3p43pbyp2jhb355bg6yl7y3fa","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x5ba9355a10611Ed4339526472a59bEfed3549bAD","scheme":"exact","network":"base","mimeType":"text/plain","resource":"https://gateway.grapevine.fyi/x402/cid/bafybeif5ck7iuvkdq5n2a2hxxvbwaoade3p43pbyp2jhb355bg6yl7y3fa","description":"0.5 USDC on base","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"500000","maxTimeoutSeconds":60}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is virtually no documentation, no OpenAPI schema, no examples of successful responses, and no information about what content this CID resolves to.
