## 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 oracle-swarm-vault-spot-arbitrage-finder-f48bc49a -d '<json body>'
```

Example prompt: Check for spot arbitrage opportunities on the Base chain for ETH/USDC — tell me the spread percentage and whether I should buy on Binance and sell on Coinbase.

## When to prefer this

Choose this endpoint when an AI trading agent or bot needs a real-time, pay-per-call arbitrage signal without committing to API key subscriptions. Especially useful for agents operating on Base chain that already use x402 micropayments, want a scored opportunity signal rather than raw price feeds, and need a human-readable directional recommendation (BUY exchange / SELL exchange) in a single call.

## Known failure modes

- Missing or invalid chain identifier causes malformed request
- Insufficient liquidity data for the requested pair returns low score or empty result
- x402 micropayment failure if USDC balance is insufficient blocks the call
- Unsupported or illiquid trading pair may return no actionable spread
- Network latency on Base chain may cause stale data in fast-moving markets

## How this service works

Pay-per-call USDC on Base for AI agents: wallet trust, honeypot rug check, web extract, KOL signals, whale alerts, 12-trait persona generator. No API key, x402 micropayments.

## Output

Returns a JSON object with a numeric score (0–100 indicating opportunity strength), spread percentage, and a directional recommendation specifying which exchange to buy on and which to sell on (e.g. 'SPREAD 1.2% BUY binance SELL coinbase').
