Instead of requiring a Pinata account or API key, the endpoint uses Coinbase's x402 payment protocol: an unauthenticated GET request returns an HTTP 402 challenge, and once payment is made the private content is served back.\n\nThe endpoint is part of Pinata's account-free IPFS service suite, which also offers public and private file uploads. Private files pinned through the companion upload endpoint can later be retrieved through endpoints like this one by paying per-request. The x402 challenge mechanism handles payment negotiation automatically when used with an x402-compatible client (e.g., `fetchWithPayment` from the x402 SDK).\n\nNote that the specific CID in this endpoint URL (`bafkreifm6sroj5jdnkbjojh5ra5hiybj3rwq52focjvaup7dn5amqll4ne`) is baked into the path, meaning this particular listing retrieves one specific private file. The general pattern is `https://402.pinata.cloud/v1/retrieve/private/{cid}`. Documentation is available at docs.pinata.cloud/files/x402, though the on-server /docs path returns 404. The x402 challenge was captured live but returned an empty challenge body, so pricing details and accepted payment methods could not be confirmed 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 retrieval","Pinata private file","CID retrieval","x402 IPFS","pay-per-file IPFS","decentralized storage retrieval","Pinata x402","private IPFS gateway"],"warnings":["x402 challenge body was empty — pricing and accepted payment methods could not be determined from the probe","No OpenAPI or schema documentation available at the endpoint origin","The /docs path on the server returns 404; full docs are hosted externally at docs.pinata.cloud/files/x402","This endpoint URL is CID-specific; the listing represents retrieval of one particular private file, not a general-purpose API"],"endpointUrl":"https://402-server.pinata-marketing-enterprise.workers.dev/v1/retrieve/private/bafkreifm6sroj5jdnkbjojh5ra5hiybj3rwq52focjvaup7dn5amqll4ne","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/bafkreifm6sroj5jdnkbjojh5ra5hiybj3rwq52focjvaup7dn5amqll4ne","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":"0.450","qualityRationale":"The endpoint is live (402 challenge captured) but the challenge body is empty, so pricing, accepted tokens, and payment details are unknown.
