Market-implied Brazilian inflation breakeven — Fisher's EXACT identity ((1+nominal)/(1+real) - 1), never the linear approximation — computed only where the nominal and real curves both have support at the same tenor (method_id breakeven_fisher_v1). Returns `nominal_zero_rate_pct` and `real_zero_rate_pct` alongside the breakeven so the result is auditable. IMPORTANT: this is NOT "expected inflation" — it embeds risk premium, liquidity and convexity effects. The response field is deliberately named `market_implied_inflation_breakeven`. Use when: assessing what the market is pricing for future inflation, as distinct from Focus survey expectations (use brazil_focus_revisions with indicator="IPCA" for that). Do not use when: you need either curve alone (use brazil_yield_curve / brazil_real_curve). Args: as_of: optional YYYY-MM-DD. Defaults to today. tenors: comma-separated subset of 1Y,2Y,3Y,5Y,7Y,10Y. Default: all. quote_side: "buy", "sell", or "mid" (default). payment_token: required in staging ($0.03/call per pricing.yaml).
