## 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-research-brief-cross-asset-market-data-e3f1b351
```

Example prompt: Pull me a Losbeto research brief right now — I need multi-oracle price consensus and sentiment for BTC, current EUR/USD forex rate, and any Brazil macro signals from BCB.

## When to prefer this

Choose this endpoint when you need a single-call, pay-per-use cross-asset market data brief without API key registration — especially valuable for AI agents needing multi-oracle crypto price consensus, Brazil-specific macro data (BCB/B3), or a combined forex/equities/commodities snapshot. Prefer over traditional data providers when your agent uses x402 micropayment flows on Base or Solana and you want zero-setup, zero-subscription access to broad market coverage.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or unsupported asset symbol — returns error in JSON body
- Network or oracle data unavailability — may return partial data or 503
- Malformed request parameters — returns 400 Bad Request

## 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 research brief containing aggregated market data across multiple asset classes: multi-oracle price consensus (crypto), sentiment consensus, live forex rates, equity prices, commodity prices, Brazil-specific macro indicators from BCB and B3, all returned in a single structured response.
