Pay 0.1 USDC (Base Sepolia) to retrieve a file by CID from Grapevine/Pinata gateway.
What it does
This x402-enabled endpoint serves content-addressed files (identified by IPFS CID) behind a micropayment wall. The specific resource at this URL returns the file with CID `bafkreiba5ig2rf7p6zwcngfrjwfehjnd447kwverku57ln5jixfbtlr6ry` in exchange for a payment of 0.1 USDC on the Base Sepolia testnet. The endpoint follows the x402 protocol (version 1) using the "exact" payment scheme, meaning the caller must supply a valid `x-payment` header to unlock the content.
The gateway is hosted on `grapevine.dev-mypinata.cloud`, which appears to be a development/testnet instance of a Pinata-based IPFS gateway augmented with x402 payment gating. The response MIME type is `application/octet-stream`, indicating raw binary content delivery. Payments are directed to address `0x70F9C8BeF5e9561D237FEF058424e792B9fA9b1d` using the USDC token contract at `0x036CbD53842c5426634e7929541eC2318f3dCF7e` on Base Sepolia, with a maximum timeout of 60 seconds.
Note: This endpoint operates on a testnet (Base Sepolia), so it uses test USDC rather than real funds. No documentation, OpenAPI spec, or additional pages were found on the host — all non-CID routes return errors. The service appears to be a minimal, single-purpose gateway for paid IPFS content retrieval.
Capabilities
Use cases
- —Paying to retrieve a specific IPFS-pinned file via x402 micropayment
- —Gating access to content-addressed data behind on-chain payments
- —Testing x402 payment flows on Base Sepolia testnet
Fit
Best for
- —Developers testing x402 payment-gated content delivery
- —Retrieving specific IPFS files behind a paywall
- —Experimenting with micropayment-based IPFS gateways on testnet
Not for
- —Production/mainnet paid content delivery (this is testnet only)
- —Browsing or searching IPFS content — only serves a single known CID per URL
- —Free or unauthenticated IPFS file retrieval

Quality
Only the x402 challenge metadata is available. No documentation, no OpenAPI spec, no example responses, and no additional pages were found. The host returns errors for all non-CID routes. This is effectively a stub listing inferred entirely from the payment challenge.
Warnings
- —Testnet only (Base Sepolia) — not suitable for production use with real funds
- —No documentation or OpenAPI spec found on the host
- —All non-CID routes return errors; the service appears to be a minimal dev deployment
- —Response content is opaque (application/octet-stream) with no description of what the file contains
- —No robots.txt or agents.txt present
