## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability gateway-grapevine-fyi-7e844666 -d '<json body>'
```

Example prompt: Fetch the content stored at IPFS CID bafkreihdwc6aggyoqg2oa5mnwbppiohtc47epwsq7gwhmmln7cqoynxt6m through the Grapevine gateway on base-sepolia testnet.

## When to prefer this

Use this endpoint when you need to retrieve content addressable via a specific IPFS CID and are operating on the base-sepolia testnet environment. Prefer this over mainnet Grapevine endpoints when testing or developing, since the cost is in testnet USDC. Choose this over public IPFS gateways when the content is gated behind micropayment access control via the x402 protocol.

## Known failure modes

- Payment not accepted — insufficient USDC balance on base-sepolia
- CID not found or not pinned by this gateway — 404 response
- Network unavailable — base-sepolia testnet connectivity issues
- Invalid CID format — malformed content identifier
- Gateway timeout — IPFS retrieval takes too long

## How this service works

0.05 USDC on base-sepolia

## Output

Returns the raw content payload associated with the specified IPFS CID — could be a file, document, JSON blob, or other data originally pinned to IPFS and made accessible through this paid gateway endpoint.
