name: grapevine.dev-mypinata.cloud
description: grapevine.dev-mypinata.cloud exposes a single paywalled IPFS file retrieval endpoint. It serves one hardcoded IPFS CID (bafkreibculhjx6ypm4dmxlko4a2bdezbq3le5cazx5mnbmsxsl6eqceme4) and requires a 1 USDC payment on Base Sepolia via the x402 protocol to access the raw file contents.
host: grapevine.dev-mypinata.cloud

# grapevine.dev-mypinata.cloud

This host is a minimal demonstration or production instance of Grapevine's x402-based IPFS paywall, built on Pinata infrastructure. It serves a single pinned file behind a micropayment gate, targeting agents or applications that need to retrieve that specific CID and are capable of executing x402 USDC payments on Base Sepolia. It is not a general-purpose IPFS gateway.

## When to use this host

Use this host only when an agent specifically needs the file stored at IPFS CID bafkreibculhjx6ypm4dmxlko4a2bdezbq3le5cazx5mnbmsxsl6eqceme4 and can pay 1 USDC on Base Sepolia via x402. Do not use this host for arbitrary IPFS CID lookups — it will not serve any other CID. Do not use it if the agent lacks a funded Base Sepolia wallet or cannot participate in the x402 payment protocol. For general IPFS retrieval, use a public gateway (e.g., ipfs.io, Cloudflare IPFS) or a configurable Pinata gateway instead.

## Capabilities

### Paywalled IPFS File Retrieval

Fetches the raw contents of a single hardcoded IPFS-pinned file after satisfying a 1 USDC x402 payment on Base Sepolia.

- **`fetch-ipfs-cid-via-grapevine`** — Retrieves the raw file stored at IPFS CID bafkreibculhjx6ypm4dmxlko4a2bdezbq3le5cazx5mnbmsxsl6eqceme4 via the Grapevine paywall, requiring 1 USDC on Base Sepolia.

## Skill reference

### `fetch-ipfs-cid-via-grapevine`

**Grapevine CID Paywall (USDC)** — Retrieves the raw file stored at IPFS CID bafkreibculhjx6ypm4dmxlko4a2bdezbq3le5cazx5mnbmsxsl6eqceme4 via the Grapevine paywall, requiring 1 USDC on Base Sepolia.

*Use when:* Use when an agent needs to fetch the specific IPFS-pinned file at CID bafkreibculhjx6ypm4dmxlko4a2bdezbq3le5cazx5mnbmsxsl6eqceme4 and is prepared to pay 1 USDC on Base Sepolia via the x402 payment protocol.

*Not for:* Do not use for arbitrary IPFS CID retrieval; this endpoint serves only the single hardcoded CID. Do not use if the agent cannot fulfill x402 USDC payments on Base Sepolia.

**Returns:** Returns the raw binary content (application/octet-stream) of the IPFS file pinned at the specified CID after payment is verified.

**Example:** `GET https://grapevine.dev-mypinata.cloud/x402/cid/bafkreibculhjx6ypm4dmxlko4a2bdezbq3le5cazx5mnbmsxsl6eqceme4`
