## When to prefer this

Choose this endpoint when you need the official, authoritative Selic policy target rate directly sourced from Banco Central do Brasil's SGS system (series 432) with proper attribution and ODbL licensing. Prefer it over web scraping or unofficial aggregators for compliance-grade macro analysis, monetary policy monitoring, or financial model inputs requiring a traceable, licensed data source.

## Known failure modes

- Data source unavailable: BCB SGS API is temporarily down, resulting in an empty or error response
- Stale data: if BCB has not published a new observation, the latest value may be from a prior business day
- Network timeout: the upstream request to BCB SGS times out
- Payment failure: x402 payment not processed, request blocked
