## 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 deposit-now-x402-agent-funding-rail-usdc-on-base-e0b2b0db
```

Example prompt: Send $50 USDC to my trading agent wallet at 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb0 — note it in the memo as 'weekly top-up'. I'll cover the 1% fee on top.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically fund an EVM wallet or spin up a new managed CDP child wallet with USDC on Base, particularly within x402-native agentic workflows where no API key is desired. Prefer it over manual wallet transfers or centralized fiat on-ramps when the caller already holds USDC on Base and needs a low-friction, receipt-generating funding rail with a stable 1% fee model. It is especially well-suited for multi-agent architectures where sub-agents need their own funded wallets provisioned on demand.

## Known failure modes

- Insufficient USDC balance in the calling agent's wallet to cover amount + 1% fee — payment rejected at x402 layer
- Missing or invalid target EVM address when provision is false — request rejected
- provision:true sent alongside a target address — conflicting parameters cause request failure
- label not provided when provision:true and no Idempotency-Key set — required field missing error
- Amount below $0.01 or above $100,000 — out-of-range validation error
- x402 payment handshake failure — network or facilitator unavailability
- memo exceeding 256 characters — validation error

## How this service works

Open x402 funding rail: POST target+amount or provision:true+label+amount; pay 0.25% (min $0.001, max $0.25) via x402 on Base or Solana; net forwarded on the same chain. Optional managed child wallets (CDP, Base only). Optional public receipt when storage is configured.

## Output

Returns a JSON object confirming the payment was received, including: the receipt ID and URL for auditing, the gross amount paid (net + 1% fee), the fee amount, the net deposit amount forwarded, the target wallet address, the forward settlement status, and a boolean indicating whether a new child wallet was provisioned.
