Choose this endpoint when you need Brazil-specific macroeconomic revision data from official sources (BCB/B3) without setting up API keys or accounts, and you want pay-per-call pricing via USDC micropayments on Base, Solana, or Algorand.

## Known failure modes

- Network timeout if Losbeto servers are temporarily unavailable
- Stale or no revisions available returns empty dataset
