## 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-arbitrage-x402-ai-trading-swarm-4cb8a2bc
```

Example prompt: Check Losbeto's arbitrage endpoint for any current price spread opportunities between Solana and Base that an AI trading bot could exploit right now.

## When to prefer this

Choose this endpoint when an AI trading agent needs low-cost ($0.15 USDC), on-demand arbitrage signal data specifically spanning Solana and Base networks, paid via x402 micropayment protocol. Prefer over generic market data APIs when you need cross-chain spread detection in a pay-per-call model without subscriptions.

## Known failure modes

- 402 Payment Required if USDC payment header is missing or insufficient (requires $0.15 USDC per call)
- Malformed or empty response if 'properties' query param is invalid or unsupported
- No opportunities returned if markets are currently balanced (empty result set)
- Timeout or 5xx if backend trading swarm is temporarily unavailable
- Schema ambiguity — input schema is poorly documented, unexpected param names may be silently ignored

## 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

A JSON object containing detected arbitrage opportunities across Solana and Base chains, including token pairs, price spreads, potential profit margins, and relevant chain metadata. Exact schema fields are minimally documented but response is JSON.
