## 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-agent-call-x402-ai-trading-swarm-4d6a8e66
```

Example prompt: Call the Losbeto AI trading swarm agent with my trading parameters and pay for it using USDC on Base via x402 — I want to execute a multi-chain trade action.

## When to prefer this

Choose this endpoint when you need to invoke a pay-per-call AI trading agent that supports x402 USDC micropayments on Solana or Base. Prefer it over traditional REST APIs when your agent workflow requires on-chain payment settlement and multi-chain trading automation without pre-negotiated API keys.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted
- Invalid properties input: malformed or missing agent call parameters
- Network error: Solana or Base chain unavailable
- 402 Payment Required: x402 handshake fails
- Endpoint unavailable: one of the 67 swarm endpoints is offline
- Timeout: agent computation exceeds response time limit
