With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability gateway-grapevine-fyi-70f9de2c -d '' ``` Example prompt: Fetch the Grapevine-gated content at CID bafkreie6t4rl5jij2vyxp4hp4gkpqexnklavf3p43zet23sj4b6eybuaca — it costs 1 USDC on Base via x402, go ahead and pay and return whatever is behind the paywall. ## When to prefer this Use this endpoint when you need to retrieve a specific piece of content identified by CID bafkreie6t4rl5jij2vyxp4hp4gkpqexnklavf3p43zet23sj4b6eybuaca that is gated behind a 1 USDC x402 micropayment on Base. Prefer this over cheaper sibling endpoints when this exact CID is the target resource. ## Known failure modes - Insufficient USDC balance — payment rejected, 402 response returned - Invalid or expired payment header — authorization fails - CID not found or content unavailable — 404 response - Network congestion on Base causes payment confirmation delay - Incorrect payment amount (not exactly 1 USDC) — rejected ## How this service works 1 USDC on base ## Output The raw paywall-protected content stored at the specified IPFS CID, returned after a successful 1 USDC micropayment on the Base network via the x402 protocol. ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/gateway-grapevine-fyi-70f9de2c/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from gateway.grapevine.fyi](https://www.zero.xyz/host/gateway.grapevine.fyi/llms.txt)
