## 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-founding-agent-cross-asset-market-data-1d49eff6
```

Example prompt: Pull the latest multi-oracle consensus price for Bitcoin plus the current USD/BRL forex rate and any available market sentiment score — I need all three in one shot from Losbeto.

## When to prefer this

Choose this endpoint when your agent needs cross-asset market data without managing API keys or subscriptions, especially when you need multi-oracle price consensus for crypto (reducing single-source manipulation risk), or when you need Brazilian market data (BCB/B3) alongside global assets. Ideal for pay-per-use agent workflows where you only pay when market data is actually needed. Prefer over subscription-based alternatives when call volume is sporadic or unpredictable.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402 requiring x402 payment on Base or Solana
- Invalid or unrecognized asset symbol — returns error with no market data
- Network or oracle unavailability — partial or empty data returned for affected asset classes
- Malformed request parameters — 400 error with description of missing or invalid fields

## 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 one or more of: multi-oracle aggregated crypto prices, sentiment consensus scores, forex exchange rates, equity prices, commodity prices, and Brazil-specific macro indicators from BCB and B3. The exact fields returned depend on which asset classes are queried, but all data is aggregated and consensus-based rather than from a single source.
