Pay 0.01 USDC (Base Sepolia) to retrieve a specific IPFS CID via x402 paywall.
What it does
This x402-enabled endpoint serves content stored on IPFS (via Pinata) behind a micropayment wall. The resource is identified by a specific CID (bafkreifu5rll4aar7sa5vqvbtzycxdog5nivkhn5crf7ajkc6ga3gqcg4i) and costs 0.01 USDC on the Base Sepolia testnet. The endpoint uses the x402 "exact" payment scheme, accepting payment to address 0xbc03df2D9F44Cc552EbbFF39860f2CC4fC751d0E with a 60-second timeout. The USDC asset contract is 0x036CbD53842c5426634e7929541eC2318f3dCF7e.
The service appears to be hosted on a Pinata-based gateway (grapevine.dev-mypinata.cloud) that wraps IPFS content retrieval behind x402 payment challenges. A GET request without a valid x-payment header returns a 402 challenge describing the required payment. The response MIME type is application/octet-stream, indicating the content is served as raw binary data.
Documentation is absent — all crawled paths (root, /docs, /api, /pricing, /README) returned error pages. The service is on a testnet (Base Sepolia), so it is likely experimental or in development. No OpenAPI spec, agents.txt, or ai-plugin manifest was found.
Capabilities
Use cases
- —Paying to retrieve a specific IPFS-hosted file via x402 micropayment
- —Testing x402 payment flows on Base Sepolia testnet
- —Agent-driven content purchase from IPFS gateways
Fit
Best for
- —Developers testing x402 payment integrations on testnet
- —Agents that need to programmatically purchase IPFS-hosted content
- —Experimenting with micropayment-gated decentralized storage
Not for
- —Production use (this is on Base Sepolia testnet)
- —Browsing or discovering available content (only a single CID is exposed)
- —Free IPFS content retrieval

Quality
Minimal information available. No documentation, no OpenAPI spec, no examples, and the service is on a testnet. The only concrete data comes from the x402 challenge response. All crawled pages returned errors.
Warnings
- —Testnet only (Base Sepolia) — not suitable for production use
- —No documentation found at any crawled path
- —Single CID endpoint — unclear if other CIDs are supported via the same pattern
- —No OpenAPI spec or API documentation available
- —Response content type is application/octet-stream with unknown payload structure
- —Service may be experimental or in early development
