## 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 losbeto-cross-chain-usdc-payment-endpoint-43e8a684
```

Example prompt: Send a cross-chain USDC micropayment from my Solana wallet to a Base wallet address — I need to settle a $0.15 USDC payment for an AI agent API call using the Losbeto x402 cross-chain endpoint.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically settle USDC micropayments across Solana and Base blockchains using the x402 payment protocol, especially for per-call API billing in multi-chain agent workflows where payment amounts start at $0.003 USDC.

## Known failure modes

- Insufficient USDC balance on source chain leading to payment failure
- Invalid or missing wallet address properties causing bad request error
- Chain network congestion or RPC failure resulting in timeout
- Unsupported chain combination returning error response
- Malformed input schema causing 400 bad request
- x402 payment protocol handshake failure

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

Returns a JSON response containing the cross-chain payment result, including transaction status, confirmation details, source and destination chain identifiers, and USDC transfer amount settled.
