{"id":"7826fb45-8f2d-4671-902b-2cfa10b0df45","shortId":"mmVRyK","kind":"mpp","title":"Upload files to IPFS via Pinata without an account — pay per request with Tempo stablecoins over MPP.","tagline":"Upload files to IPFS via Pinata without an account — pay per request with Tempo stablecoins over MPP.","description":"This MPP endpoint lets you upload public files to IPFS through Pinata's infrastructure without creating an account or using an API key. Payment is handled inline via the Machine Payments Protocol (MPP) using Tempo stablecoins on chain 4217. The endpoint returns a signed upload URL that you then use with the Pinata SDK to complete the file upload.\n\nThe payment challenge advertises an amount of 1000 base units in a stablecoin on the Tempo L2 (chain ID 4217). Assuming 6 decimals (typical for stablecoins), this translates to $0.001 per request as a base charge; the listing title suggests dynamic pricing based on file size ($0.10/GB/month, minimum $0.01). The caller passes a `fileSize` query parameter so the server can compute the appropriate charge. Once paid, the response provides a pre-signed URL for uploading the actual file content via the Pinata SDK's `upload.public.file().url()` method.\n\nUploaded content is publicly available on any IPFS gateway or through a Pinata Dedicated IPFS Gateway. The intent is \"charge\" (one-shot payment per call), and settlement occurs on Tempo L2. No API key or Pinata account is required — the MPP payment itself authorizes the request.","tags":["ipfs","pinata","storage","files","upload","download","cid"],"capabilities":["ipfs-upload","ipfs-pinning","public-file-hosting","account-free-access","tempo-settlement","mpp-payment","file-storage"],"categories":["storage","crypto"],"synonyms":["IPFS upload","IPFS pinning","decentralized file storage","Pinata upload","IPFS hosting","file pin","content-addressable storage","web3 storage"],"warnings":["No OpenAPI or formal API documentation available — /docs, /api, and /pricing all return 404.","The stablecoin currency at address 0x20C0…8b50 on chain 4217 is not independently identified; 6 decimals is assumed but unconfirmed.","Dynamic pricing model ($0.10/GB/month, min $0.01) is stated in the existing listing title but not corroborated by any crawled page.","Response JSON shape ({url}) is inferred from the landing page code example, not from a schema or documentation."],"endpointUrl":"https://mpp.pinata.cloud/v1/pin/public","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"mpp.pinata.cloud","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.500","qualityRationale":"The endpoint is live (402 challenge captured) and the landing page provides a working code example, but there is no OpenAPI schema, no formal docs (docs/api/pricing all 404), and the response shape is inferred from the code snippet rather than documented.
