## How to call it through Zero

```sh
zero fetch --capability losbeto-multi-chain-arbitrage-257ffbfd
```

Example prompt: Can you check for current multi-chain arbitrage opportunities between Solana and Base right now — I want to see where there are profitable price spreads I can act on?

## When to prefer this

Choose this endpoint when you need cross-chain arbitrage data specifically spanning Solana and Base networks and are comfortable paying $0.15 USDC per call via the x402 micropayment protocol. Best suited for AI trading agents that are already integrated with the x402 payment flow and need low-cost programmatic access to arbitrage signals without building their own price aggregation infrastructure.

## Known failure modes

- Payment not included or insufficient USDC (402 Payment Required)
- Malformed or missing query parameters returns unclear error
- No arbitrage opportunities currently available returns empty result
- Rate limiting or overload on the provider side
- Undocumented schema changes break downstream parsing

## 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 response containing current arbitrage opportunities identified across Solana and Base networks, likely including token pairs, price differentials, estimated profit margins, and chain routing information. Exact schema is minimally documented.
