Pay 0.25 USDC on Base Sepolia to retrieve a pinned IPFS file via Pinata gateway.
What it does
This x402-enabled endpoint serves IPFS content identified by a specific CID (bafkreicilic7mgda6sfqwokucrvxeuwbtv46l26jorawo45xll4ryshd2i) through a Pinata-hosted gateway at grapevine.dev-mypinata.cloud. Access requires an x402 payment of 0.25 USDC on the Base Sepolia testnet. The content is returned as application/octet-stream upon successful payment.
The endpoint follows the x402 protocol (version 1) with an "exact" payment scheme. Callers must include a valid `x-payment` header containing proof of payment to the designated wallet address. The payment asset is USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e) on Base Sepolia, with a maximum timeout of 60 seconds for payment verification.
Note that this runs on Base Sepolia, a testnet, so the USDC involved has no real monetary value. The gateway appears to be a Pinata-based IPFS gateway that gates content retrieval behind x402 micropayments. Documentation is not available — the host returns error messages for all non-CID routes, suggesting it functions purely as a content-serving gateway rather than a general-purpose API.
Capabilities
Use cases
- —Retrieving gated IPFS-pinned content by paying a micropayment
- —Testing x402 payment flows on Base Sepolia testnet
- —Building pay-per-download file distribution systems on IPFS
Fit
Best for
- —Developers testing x402 payment integrations on a testnet
- —Agents that need to fetch specific gated IPFS content
- —Prototyping pay-per-access content delivery over IPFS
Not for
- —Production mainnet file hosting (this is on a testnet)
- —Browsing or searching IPFS content — this serves a single specific CID
- —Hosting or pinning new content — this is read-only retrieval

Quality
The endpoint is live and returns a well-formed x402 challenge, but there is no documentation, no OpenAPI schema, no examples, and the crawl yields only error pages. The listing description and title are minimal. The endpoint serves a single CID on a testnet, limiting its general utility.
Warnings
- —No documentation available — all non-CID routes return errors
- —Runs on Base Sepolia testnet; USDC has no real value
- —Serves a single specific CID; unclear if other CIDs are supported at this gateway
- —Response content type is application/octet-stream with unknown payload format
