## 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 amanchain-arbitrage-spread-scanner-e89dd606 -d '<json body>'
```

Example prompt: Scan the live on-chain pools right now for any profitable arbitrage spreads — I want to see current price differentials and spread opportunities across DEX pairs using the AmanChain arb scan service.

## When to prefer this

Choose this endpoint when you need real-time, deterministic on-chain arbitrage spread data computed directly against live block state rather than off-chain price feeds or aggregated market data. It is ideal for DeFi trading agents, arbitrage bots, and on-chain analytics workflows that require trustless, node-executed computation paid per call with no account or API key setup.

## Known failure modes

- Node unavailable or consensus state out of sync — returns error with node status
- Malformed request body or missing serviceId — returns 400-level validation error
- x402 payment failure or insufficient USDC balance — returns 402 Payment Required
- No arbitrage spreads detected in current block state — returns empty or zero-result response
- Rate limiting or node congestion during high block activity — returns timeout or 503

## How this service works

Arbitrage Spread Scan: node-operated on-chain service Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-arb-scan","request":"<input>"}. No account, no API key.

## Output

Returns detected arbitrage spread opportunities across on-chain DEX pools, including token pairs, spread percentages, pool balances, and potential profit margins, computed deterministically against live consensus state at the time of the call.
