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 object containing Brazil's key interest rate metrics: the Selic policy target rate, CDI overnight rate annualized on the 252-business-day convention, TJLP long-term rate, 12-month IPCA inflation reading, the real interest rate computed via the Fisher relation (not naive subtraction), the CDI-versus-Selic spread as a data sanity indicator, and a carry-trade attractiveness reading for BRL.
Example use cases
EM carry trade screening
“Pull the latest Brazil interest rate curve for me — I need the CDI overnight, Selic target, real rate, and the carry-trade signal to evaluate whether BRL is worth including in my emerging market carry basket.”
Brazil macro briefing for investment report
“I'm writing a Brazil macro update — can you get me the current Selic policy rate, CDI rate, TJLP, 12-month IPCA, and the Fisher real rate so I have the full rate structure?”
CDI-Selic spread data quality check
“I want to verify Brazil's CDI-Selic spread right now as a data sanity check — fetch the br-curve data and tell me how wide the spread is and whether it looks normal.”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/br-curve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Brazil-specific interest rate data including Selic, CDI (252-day convention), TJLP, IPCA, and carry-trade signals without API key setup — particularly for EM macro analysis, carry-trade screening, or fixed-income research. Prefer over generic forex or macro providers when you need BCB/B3-sourced Brazilian rates with Fisher-relation real rate computation and no account registration, paying only per call in USDC.
Side effects
- Payment not received or invalid USDC payment — returns 402 Payment Required
- BCB or B3 source data unavailable — may return stale or error response
- Invalid format query parameter — may return 400 or default to JSON
- Network timeout from upstream data provider
