It uses the Coinbase x402 payment protocol, meaning callers pay per-request with cryptocurrency — no Pinata account or API key required. The endpoint returns an HTTP 402 challenge to unauthenticated callers, and upon successful payment the private file content is served.\n\nThe endpoint is part of Pinata's account-free IPFS access suite, which also includes public and private upload endpoints. Private files on Pinata are not accessible through public IPFS gateways, so this paid retrieval mechanism is the intended way to fetch them. The CID in the URL path (bafkreieoyh26ynfux2pldujpawobz6mqxkvlxcmyu2n6vhfqgcmmd5vh2u) identifies the specific file to retrieve.\n\nDocumentation is sparse: the landing page at the origin provides code examples for uploading but not for retrieval, and the full docs link points to docs.pinata.cloud/files/x402 which was not crawled. No OpenAPI schema, pricing details, or response format documentation were found in the probe or crawl material. The endpoint is confirmed live (402 challenge returned on GET), but the challenge object itself was empty, so payment parameters (price, accepted tokens, network) could not be determined from the probe alone.","tags":[],"capabilities":["ipfs-private-file-retrieval","x402-payment","cid-based-access","account-free-access","crypto-payment"],"categories":["storage","crypto"],"synonyms":["IPFS file download","Pinata private file","CID retrieval","paid IPFS gateway","x402 IPFS","decentralized storage retrieval","private IPFS content"],"warnings":["Empty x402 challenge object — payment parameters (price, token, network) unknown from probe","No OpenAPI or schema documentation available","Full docs at docs.pinata.cloud/files/x402 were not crawled; details may exist there","No pricing information found in crawl material","This endpoint URL is CID-specific; it retrieves one particular file, not a general retrieval API"],"endpointUrl":"https://402-server.pinata-marketing-enterprise.workers.dev/v1/retrieve/private/bafkreieoyh26ynfux2pldujpawobz6mqxkvlxcmyu2n6vhfqgcmmd5vh2u","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xc900f41481B4F7C612AF9Ce3B1d16A7A1B6bd96E","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://402-server.pinata-marketing-enterprise.workers.dev/v1/retrieve/private/bafkreieoyh26ynfux2pldujpawobz6mqxkvlxcmyu2n6vhfqgcmmd5vh2u","description":"Pay to retrieve a private file from Pinata by CID","outputSchema":{"input":{"type":"http","method":"GET","pathParams":{"cid":{"type":"string","required":true,"description":"Content Identifier (CID) of the file to retrieve"}}},"output":{"type":"object","properties":{"url":{"type":"string","description":"Temporary access URL for the private file"}}}},"maxAmountRequired":"100","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live with a 402 challenge on GET, but the challenge object is empty, no schema or OpenAPI spec exists, no pricing or response format documentation was found in the crawl, and the /docs path returns 404.
