## 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 x402factory-ai-6d3ab76c -d '<json body>'
```

Example prompt: Bridge 50 USDC from my Solana wallet to my Base wallet address 0xAbC123...def — I know there's a 2.5% commission so I'll receive about 48.75 USDC on Base.

## When to prefer this

Use this endpoint when you need to move exactly 50 USDC from Solana to the Base network in a single atomic operation with built-in retry logic and automatic refund guarantees. Prefer this over manual bridging when you want an API-native, x402-payment-gated cross-chain transfer with predictable fees (2.5%) and failure handling.

## Known failure modes

- Base transfer fails after 2 attempts — full 50 USDC refund issued on Solana
- Solana refund fails after 3 attempts — bridge marked as failed, manual support required
- Invalid Base receiver address — transfer cannot be completed
- Insufficient liquidity on Base side — delivery attempt fails
- Payment not confirmed on Solana — bridge never initiated

## How this service works

Solana → Base USDC microbridge. This request will accept a payment of 50.000000 USDC on Solana to the bridge wallet and, after a 2.5% commission of approximately 1.250000 USDC, will attempt to deliver around 48.750000 USDC on Base to the specified receiver. If the Base transfer cannot be completed after 2 attempts, the bridge refunds the full original amount on Solana; if the refund also fails after 3 attempts, the bridge is marked as failed and manual support is required.

## Output

The bridge accepts 50 USDC on Solana, deducts a ~1.25 USDC (2.5%) commission, and delivers approximately 48.75 USDC to the specified Base receiver address. On success, returns confirmation of the Base transfer. On failure after 2 delivery attempts, initiates a full refund of 50 USDC on Solana. If refund also fails after 3 attempts, the bridge is marked as failed and requires manual support intervention.
