Pay-per-access IPFS content retrieval via x402 on Base Sepolia (0.07 USDC per request).
What it does
This x402 endpoint serves IPFS content gated behind a micropayment of 0.07 USDC on the Base Sepolia testnet. The URL structure indicates it is hosted on a Pinata-based gateway (dev-mypinata.cloud) under the "grapevine" subdomain, and the path includes a specific CID (bafybeiffjwkdfy5lemdom3jmt2cb3uixtrbptq46gkznyyoqvdgeswqebm) identifying the pinned content.
The endpoint is designed to return the IPFS-pinned file once a valid x402 payment header is supplied. The price is 0.07 USDC (70,000 base units at 6 decimals) settled on Base Sepolia. During probing, the endpoint returned HTTP 429 on GET (rate-limited) and 405 on POST, which suggests the endpoint is live but may require specific request conditions or headers to surface the standard 402 challenge. No OpenAPI schema, documentation, or additional metadata was found on the origin domain — all non-CID paths return an "Invalid URL" error, consistent with a purpose-built IPFS gateway rather than a general-purpose API.
Because the crawl yielded almost no documentation and the 402 challenge was not directly captured, the listing is based primarily on the Bazaar record and URL structure. Buyers should expect to supply a valid x402 payment proof in the request header to retrieve the gated content.
Capabilities
Use cases
- —Paying to retrieve a specific IPFS-pinned file behind a micropayment wall
- —Testing x402 payment flows on Base Sepolia testnet
- —Monetizing pinned IPFS content via per-request USDC micropayments
Fit
Best for
- —Developers experimenting with x402 payment-gated IPFS content
- —Testnet-based micropayment prototyping
- —Serving premium or gated decentralized content
Not for
- —Production mainnet content delivery (this is on Base Sepolia testnet)
- —Browsing or discovering arbitrary IPFS content — this serves a single CID

Quality
No 402 challenge was directly captured (429 on GET, 405 on POST), no documentation or schema exists on the origin, and the crawl returned only error pages. The listing is constructed almost entirely from the Bazaar record and URL inference.
Warnings
- —The 402 payment challenge was not captured during probing — GET returned 429 (rate limit) and POST returned 405. The endpoint may be intermittently available or require specific headers.
- —No documentation, OpenAPI schema, or descriptive content found on the origin domain.
- —This endpoint operates on Base Sepolia (testnet), not mainnet — USDC used here has no real monetary value.
- —The served content (CID bafybeiffjwkdfy5lemdom3jmt2cb3uixtrbptq46gkznyyoqvdgeswqebm) is opaque; its type and size are unknown.
