## 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-b3-brazilian-equity-quote-17125f55
```

Example prompt: What's the current price of PETR4 on B3 right now — show me the BRL price, today's change, and what that works out to in USD at the official BCB rate?

## When to prefer this

Choose this endpoint when you need Brazilian equity (B3) or Ibovespa quotes denominated in BRL with an authoritative USD conversion using the official BCB PTAX rate — particularly valuable for cross-border portfolio analysis or any workflow requiring Brazil-specific macro accuracy. Prefer over generic global stock APIs that may not cover B3 tickers or use unofficial BRL/USD rates.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error response
- Market closed hours may return stale or last-close prices
- Payment failure via x402/USDC results in 402 response with no data
- Network timeout if upstream B3 or BCB data source is unavailable
- Algorand/Base/Solana payment processing delays may block the 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, Algorand and Polygon via x402.

## Output

A JSON object containing the B3 equity or Ibovespa quote with the current price in BRL, the daily price change, and the USD equivalent derived from the official BCB PTAX exchange rate.
