## 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 dbis-x402-base-cw-cdp-payment-surface-8c4e03a6
```

Example prompt: Fetch the paid content from the DBIS x402 Base cW* endpoint — it costs $0.01 USDC per call settled via Coinbase CDP on Base mainnet, so go ahead and authorize and complete that payment.

## When to prefer this

Choose this endpoint when you need to access x402-protocol-gated content specifically on the Base network (eip155:8453) using USDC or cWUSDC_V2, settled through the Coinbase CDP facilitator. Prefer this over the GRU hub routes (chain 138, Alltra) when Base mainnet settlement and Coinbase CDP integration are required.

## Known failure modes

- Payment header missing or malformed — returns HTTP 402 with payment requirements
- Insufficient USDC balance on Base — payment settlement fails
- Invalid or expired payment — 402 or 400 error returned
- Network mismatch (wrong chain) — payment rejected
- Facilitator (Coinbase CDP) unavailable — service timeout or 503

## How this service works

DBIS Base cWUSDC_V2 + USDC (Coinbase CDP)

## Output
